Crickets Orthoptera

There are numerous species of cricket to be found in Malawi, mainly of the family Gryllidae but three species have particular relevance as a food source. The giant cricket nkhululu (Brachytrypes membranaceus) is very well known, is widely distributed, and seems especially adapted to abandoned cultivations, gardens, and cleared areas in woodland. A rather plump, dark chestnut insect (HB 47 mm) it lives in burrows in the ground - to a depth of 20 cm, the males calling at their entrances in the early evening during the rains. It feeds on the roots of plants, and can at times cause serious damage to crops. It is usually obtained by being dug from its burrow, and women hoeing in coffee gardens or in similar situations will often dig up around fifty crickets during the morning. Loveridge records that in the Mulanje district young boys will often capture the cricket by means of a black army ant mdzodzo (Megaponera foetens) tied to a piece of cotton, which is lowered into the burrow - the...

Nesting and Brood Care

Extended maternal care, including provision of food for offspring, is seen in crickets, cockroaches, some Homoptera, and nonsocial Hymenoptera. For example, females of the membracid, Umbonia crassicornis, enhance offspring survival by brooding eggs, cutting slits in the bark of twigs to facilitate feeding by nymphs, and defending nymphs against predators (T. Wood 1976). Survival of nymphs with their mother present was 80 , compared to 60 when the mother was removed 2-3 days after egg hatch and 10 when the mother was removed prior to making bark slits. Females responded to predators or to alarm pheromones from injured offspring by fanning wings and buzzing, usually driving the predator away (T.Wood 1976).

Competitive Defensive and Mutualistic Behavior

Acoustic signals are used by many Orthoptera and some Coleoptera to deter competitors. Bark beetles stridulate to deter other colonizing beetles from the vicinity of their gallery entrances (Rudinsky and Ryker 1976). Subsequently, excavating adults and larvae respond to the sounds of approaching excavators by mining in a different direction, thus preventing intersection of galleries. Some male crickets and grasshoppers produce a distinctive rivalry song when approaching each other (Matthews and Matthews 1978,Schowalter and Whitford 1979). The winner (continued occupant) usually is the male that produces more of this aggressive stridulation. The type of territory differs among insect taxa, but usually it is associated with competition for food or mates (Matthews and Matthews 1978, Price 1997). Male crickets defend the area around their dens and mate with females attracted to their stridulation. Male eastern woodroaches, Cryptocercus punctulatus, defend mating chambers in rotten wood...

Biome and Landscape Patterns

Different species compose these functional groups in different biomes. For example, the insect grazer functional group is composed primarily of moths, beetles, and tree crickets in broadleaved forests, moths and sawflies in coniferous forests (Schowalter 1995, Schowalter and Ganio 1999, Schowalter et al. 1981c), grasshoppers in grasslands and shrublands (Curry 1994), and caddisflies and flies in aquatic communities (e.g., Hart 1992). The predator functional group in terrestrial arthropod communities is dominated by a variety of arachnids, beetles, flies, and wasps, whereas in aquatic arthropod communities this functional group is dominated by dragonflies, true bugs, and beetles.

Common Characteristics of Spiders

The black widow spider, Latrodectus mactans, is found in the United States from northern Massachusetts, south to Florida, and west through Louisiana, Texas, Kansas to California, and also throughout Central America. The body length of the female reaches up to 5 inches, but males are smaller. Leg span for the female is 0.75 inches, with that of males slightly longer. The main diet includes beetles, cockroaches, crickets, flies, scorpions, and spiders.

The Genetics of Behavior

The effects of hybridization on the courtship displays of dabbling duck species were the subject of a classic ethological experiment, as we saw above. A more recent set of hybridization experiments was performed on crickets. The songs of crickets, like bird songs, are species-specific, and as in birds, only male crickets sing. They do so by rubbing one wing against another wing that has a serrated edge. The sounds they produce can be recorded and analyzed quantitatively. When two species of crickets were crossed, their offspring (the Fj generation) expressed songs that had features of the songs of both parental species. Backcrosses of Fj in These genetic differences between the two parental cricket species and the hybrids were reflected in the properties of their nervous systems. When specific neurons in the crickets' brains were stimulated, songs that reflected the genotypes of the crickets were expressed.

Folk Classifications of Insects a Comparative Perspective

The Nuaulu, swidden cultivators of South Central Seram, have been extensively studied over many years by Roy Ellen (1978, 1993). From his analysis of their animal categories it would appear that, unlike many other communities, the Nuaulu have few clearly defined life-form categories, apart from Peni (loosely, large game), Mnaha (rats and mice), Manue (birds bats) and Ikae (fish and marine animals). This means that intermediate or generic levels of classification are of primary importance, and that many of these 'basic categories' are polytypic, consisting of 2-17 terminal (specific) categories. Ellen recorded some 49 folk generics - the 'basic categories' - relating to insects that together comprised around 113 terminal taxa (Ellen 1993 100-1). Thus the generic category Kauke (grasshoppers, crickets, mantids) embraces 14 terminal categories while Rikune (bugs) covers around 9 terminal categories (mostly of the families Coreidae and Pentatomidae), with the cicadas (three generics) and...

Types And Patterns Of Detritivory And Burrowing A Detritivore and Burrower Functional Groups

Boring Tunnels Wood Angiosperms Insect

Many detritivores redistribute large amounts of soil or detritus during foraging or feeding activities (e.g., Kohlmann 1991). However, nondetritivores also contribute to mixing of soil and organic matter. Fossorial functional groups can be distinguished on the basis of their food source and mechanism and volume of soil detrital mixing. Subterranean nesters burrow primarily for shelter. Vertebrates (e.g., squirrels, woodrats, and coyotes) and many invertebrates, including crickets and solitary wasps, excavate tunnels of various sizes, usually depositing soil on the surface and introducing some organic detritus into nests. Gatherers, primarily social insects, actively concentrate organic substrates in colonies. Ants and termites redistribute large amounts of soil and organic matter during construction of extensive subterranean, surficial, or arboreal nests (J. Anderson 1988, Haines 1978). Subterranean species concentrate organic matter in nests excavated in soil, but many species bring...

Teaestatemanagers Thyolo

Many other species of grasshoppers and crickets (Order Orthoptera) occasionally feed on cotton, but do not normally cause extensive damage to the crop - although in certain years they may occur in such large numbers that they inflict local damage that can be quite serious, or even total. These include the following species

Reflections on Folk Classifications

In the classification of plants in Malawi, many intermediate, functional categories are recognized, relating to potency medicines, relish, latex or ecological niches or relations (Morris 1996 40-5). But with insects few intermediate taxa seem to be evident, and the many generics are unaffiliated to any life-form category - apart from the general class of small useless organisms (kachirombo). Many of the generics, however, are widely used as general rubrics to cover several insects within a particular domain, or 'covert' class. Thus chitete is used as a general category to cover all grasshoppers of the three main families (Pyrgomorphidae, Acridae and Tettigoniidae), although I never heard the taxon used to describe the four species of crickets. Similarly, ntchenche covers many of the more conspicuous flies (of which there are several hundred species in Malawi, belonging to more than twenty different families) while nyerere is often utilized as a general category for ants. As with the...

Edible Insects of Malawi

Leaving aside the importance of honey, edible insects in sub-Saharan Africa focus essentially around five orders or groups of insects - termites, grasshoppers locusts crickets, bugs, beetles and caterpillars. The total number of edible insects in Africa probably amounts to several hundred species - or even more but the common species recorded in the literature number 113. These belong to the following families

Gravity Receptors Of The Cockroach Arenivaga Sp

Cockroach Sem

Insects as a class are generally thought to lack organs analogous to statoliths, otoliths, or semicircular canals used to sense an animal's orientation in the Earth's gravity eld. Man y insects determine their orientation by vision coupled with mech-anoreceptor information provided by limb loading and joint positions (Walthall and Hartman, 1981). Certain crickets have clavate hair sensors on their cerci, which have been shown neurophysiologically to respond to changes to the cricket's gravity orientation (Bischof, 1975). (The cerci of orthoptera are two roughly cylindrical organs projecting to the rear from the medial anal region of the insects, tapering to points. They are very noticeable in crickets and cockroaches. The cerci project at about 25 to 45 from the animal's midline depending on the species, in the horizontal plane they are generally covered with various hairlike sensillae (Hoyle, 1977). A few insects have evolved arrays of specialized gravity-sensing sensilla on their...

Golden European Moles

Golden moles inhabit grassy forests, river-banks, mountains, and semidesert areas of Africa. The smallest species is Grant's golden mole, 2.5 inches long, and the largest species is the giant golden mole, 9 inches long. Their golden fur repels water, keeping them dry while digging. When burrowing, leathery pads cover their noses, keeping dirt out. Burrowing allows foraging for insects, larvae, earthworms, crickets, slugs, snails, and spiders. Golden moles cannot see well and find food by touch. Sometimes they come to the

The Evolution of Genome Size

Coli Genome Size

Retrotransposons copy themselves with the aid of RNA, as we saw in Chapter 14. The most common type of retro-transposon carries duplicated sequences at each end, called long terminal repeats (LTRs). Occasionally, LTRs join together in the host genome, at which time the DNA between them is excised. When this happens, one of the LTRs is left behind. The number of such orphaned LTRs in a genome is a measure of how many retrotransposons have been lost. By comparing the number of LTRs in the genomes of Hawaiian crickets of the genus Laupala and those of fruit flies (Dro-sophila), investigators found that Laupala loses DNA more

Antennae

Antennae have many forms in different species. All flies have antennae, which can be of two types. The first, found in the members of the suborder Nematocera, such as crane flies, midges, and gnats, is whiplike, with two basal segments called the scape and the pedicel, as well as a flagellum of many similar segments. The second type, encountered in all members of the Brachy-cera group, has a flagellum contracted into a compound third segment. Crayfish tend to shed the oldest, most distal parts of their antennule once their carapace reaches about seven millimeters in length, and new growth occurs from the proximal end of the flagellum. The antennal flagellum also serves as the multimodal sensory organ that contains mechanoreceptors and chemoreceptors in crickets.

Chitete

Family Gryllidae Although the taxon chitete is often used as a generic or intermediate category to cover grasshoppers generally, essentially it refers to the smaller grasshoppers, especially those considered edible. The larger grasshoppers and locusts are described as chiwala (ku-wala, to shine, on account of their colourful hind wings) or dzombe. Many species belonging to the order that have salience have their own generics, while crickets tend not to be identified as chitete. The four species of crickets also have their own generic terms. Grasshoppers that are not considered edible, such as chansatsi (Abisares viridipennis) may also be described as gontham'kutu ('to deafen ears'). Given its carnivorous habits, Clonia wahlbergi is sometimes described asfisi ('witch').

Eye system

Early workers examining CE, OL unit responses explored a variety of arthropod visual systems. Burtt and Catton (1960), Ishikawa (1962), Schiff (1963) and Dingle and Fox (1966) examined single unit OL unit responses to simple changes in illumination in locusts, silkworm moths, mantis shrimp, and crickets, respectively. Not surprisingly, units were found responding to ON, OFF, and ON OFF of general illumination, as well as sustaining units that fired steadily in steady-state light or dark. Because an eye operates in a complex visual environment where many object features can be found (spatial frequency, contrast, color, relative velocity, etc.), some workers have explored how visual systems respond to certain object features, as well as to changes in overall and local illumination. Both approaches, i.e., the study of responses to simple changes in illumination, and of responses to certain object features are necessary to provide a complete understanding of how the CE visual system works.

Termites Isoptera

Insect Being Step

After collection the termites are boiled in a pot of water, the women stirring (-phatikiza) the termites continually with a porridge stick (mthiko), and removing by hand any leaves or debris. The next morning the termites are put in the sun to dry (-yanika), usually being spread over a rocky outcrop (Figure 1). When they are dried, the women winnow (-peta) the termites to remove the wings and any further debris. The termites are then in a suitable condition for cooking, or storing for future use, or, if there is a surplus, selling in the local market. The termites - the gathering may include many soldiers amongst the winged alates - are cooked in the same manner as grasshoppers and crickets heated in a pan over the fire with a little water and salt, the salt dissolving in the water (-sungunuka) and penetrating the body of the insect. As the winged termites contain a lot of fat or oil (mafuta), which is why they are so esteemed, no cooking oil is usually used in their preparation. The...

Locusts Orthoptera

Locusts and grasshoppers have been eaten by humans since time immemorial, and they are one of the few insects clearly recognized as food in the Mosaic dietary rules. They are mentioned fifty-six times in the Bible, and appear in seventeen different books - which indicates their importance as food (or pest) in Biblical times. They appear more often than any other insect, and around nine different generic names are described in the scriptures (Cansdale 1970 238-9). They are specifically distinguished from all 'winged creeping things' - which are deemed abominations - by the fact that they 'have legs above their feet, to leap withal upon the earth' (Leviticus 11 20-3). The generic names probably refer to various grasshoppers, locusts and crickets - all of which were considered edible.

Legs are attached to the lower side of the thorax. Insect legs have the same basic parts that yours do, but many insects also have extra adaptations for survival. A praying mantis's front legs have sharp spines along the edges to hold its prey. Flies have sticky pads at the end of their legs to help them walk on things, even the ceiling. Grasshoppers and crickets have large bent hind legs, just right for jumping.Water boatmen and backswimmers have legs like oars for paddling through the water. Ground beetles have long, strong legs for running.And crane flies have very long legs, helping them stand above the grass on the ground. hot liquid out of their abdomens. Fireflies have abdomens they light up to help them find their mates. Female crickets and grasshoppers have a long, skinny spear at the end of their abdomens.This is called an ovipositor and is used to lay eggs. The ovipositor on female bees and wasps has changed over time to become a stinger.

Value Paradox

The lack of correlation between genome size and complexity or gene number (C value paradox) remains a topic of study because, unless the noncoding DNA has a function, such DNA constitutes a load upon the insect and should be lost over evolutionary time. Petrov et al. (1996) provided evidence that nonessential DNA is lost at a higher rate in Drosophila species than in mammalian species, suggesting that differences in genome size may result from persistent differences between organisms in the rate of loss of nonessential DNA. Petrov et al. (2000) provided additional support for this hypothesis by comparing DNA loss in two insect genera (Laupala crickets and Drosophila) with different genome sizes. The crickets have a genome size an order of magnitude larger than that of Drosophila and eliminate nonessential DNA one-fortieth as quickly.

Premating Mechanisms

Ethological (behavioral) isolation is the most important category of premating isolation in animals. The selection of a mate and the mating process depends upon the response of both partners to various sensory cues, any one of which may be species-specific. Although one kind of sensory stimulus may be emphasized, different cues may come into play at different stages of the pairing process. Visual signals provided by color, pattern, or method of display are often of particular importance in diurnal animals such as birds, many lizards, certain spiders, and fish. Sounds, as in male mating calls, are often important in nocturnal breeders such as crickets or frogs but are also important in birds. Mate discrimination based on chemical signals or odors (pheromones) is of fundamental importance in many different kinds of animals, especially those where visual cues or sound are not emphasized chemical cues also are often important in aquatic animals with external fertilization. Tactile stimuli...

Insect Facts

Orders Common orders include Coleoptera (beetles) Diptera (flies, mosquitoes) Hemiptera (true bugs) Homoptera (cicadas), Hymen-optera (ants, bees, wasps) Isoptera (termites) Lepidoptera (butterflies, moths) Odonata (dragonflies, damselflies) Orthoptera (crickets, grasshoppers) Geographical location Every continent except Antarctica Habitat Mainly terrestrial, some aquatic, primarily freshwater Gestational period Highly variable some insects produce one, two, or several generations per year conversely, relatively large insects may take more than one year for larval development Life span Highly variable adult mayflies live less than one week, while queen termites have been known to live for more than twenty years Sound production and reception are also used for mate location. The sound generated by a female mosquito's beating wings in flight is picked up by the male mosquito's antennae. Male ho-mopterans and orthopterans produce songs of courtship. Cicadas use abdominal muscles and a...
