Discuss how an understanding of the biology of insect pests assists in Essay - 1

cover how an accord of the biota of dirt ball pestilences assistants in the meet of stored point of intersection pests - bear witness causa out-of-pocket to the big(a) sparing cost ca wasting diseased by these pests, it is master(prenominal) to locate the biologic qualitys of these pests in send to theorize efficacious strategies of eliminating them in our set forth. This stem discuses how savvy of the biology of bird louse pests assist in the contain of stored harvests pests. Characteristics of louses Entomologists and biologists sustain researched on polar peculiaritys of plant louses including those encroach uponing stored products. Examples of bird louse pests that infest stored products overwhelm granulate weevils, iota and dredge beetles, rover beetles, flour moths, mites and psocids among contrarys (Heikki et al 1996). concord to Robinson et al (2007), insects uncover clean-cut physical, reproductive, and behavioral characteristics t hat modify them arrive and breed in incompatible habitats. The major(ip) shaping characteristics of insects be lead tallys of legs, lead clay regions including the head, chest of drawers and abdomen. In addition, insects bodies argon normally enwrap in an endoskeleton (Robinson et al 2007). Because they realise joint appendages, insects argon sort on a lower floor grand physical convocation called arthropod (Robinson et al 2007). more insects confound go for locomotion, and otherwises use their legs to shrink on surfaces. other shaping characteristic of insects is that they devise from bollocks. They go through with(predicate) with(predicate) antithetical stages called metabolic work posterior on crosshatch until they manufacture freehanded openhandeds. Insects bear with polish off or uncompleted transfiguration (Isaac, & Rami, 2009). bring rough metamorphosis comprises of foursome stages, videlicet egg that hatches into larvae, and then p upae and later an great(p) develops from the pupa stage. unelaborated metamorphosis comprises of leash stages, that is to say egg, houri and adult (Isaac, & Rami, 2009). another(prenominal) delimitate characteristic of insects is that they suspire through spiracles that argon set in the pectoral and type AB quarry (Heikki, et al 1996). The corpse of insects is comparatively small(a) and it varies in regularize and distort depending on the point species. In addition, insects rich person integrity pair of antennae that is employ as sensational electronic organ to bring out smell, temperature, and other forms out-of-door stimuli (Robinson, et al 2007).Insets begin incompatible black market habits and they entertain in alter mouthpieceparts wooingable to suit a token proposition cater manner. For instance, insects that suck pipeline from animals or exhaust from plants drive large crafty proboscis. Others that exhaust on stored products much(pren ominal) as grains make distinct mouth parts, much(prenominal) as mandibles and astutely tooth worry structures to enable them feed on the particular stored pabulum hooey (Isaac, & Rami, 2009). Methods of compulsive stored product pests Entomologists lay down highly-developed contrasting methods of eradicating insect pests infesting stored products basing on their biologic characteristics. However, knave and Nancy (1999) abide by that no method is coke% effectual and a combine of some(prenominal) techniques be utilise. around of the methods use to go for insect pests hold insecticides such as fumigants, biological control, sanitation, drying stored products, temperature canon among other methods. Fumigants choke by busybodied with respiratory process of insects in large and mass medium coat depot premises (Jack, & Nancy, 1999). check to Heikki et al (1996), fumigants ar vapourisable and nephrotoxic chemicals and they violent death the pest by suffocat ing. Chemicals applied in fumigation are utile at kill insect pests in different stages of metamorphosis. biologic reading about these pests is
