“…The desert locust, Schistocerca gregaria (Forsk.) and several species of grasshoppers such as; Euprepocnemis plorans plorans, Hetracerus annulosa, Acrotylus insubricus, Chrotogonus homalodemis, Acrididella nasuta, catantops axillaris and Aiolopus strepens were found to attack agricultural crops in Egypt and many parts of the world (Maya et al, 2005;Capinera et al, 2004;Avanesyan and Culley, 2015). The desert locust and grasshoppers have a very high reproductive rate and able to respond to unfavorable climatic conditions with a rapid population increase (Bateman et al, 1993).…”

Grasshoppers are major pests of agriculture throughout much of the world. Chemical control of grasshoppers played a major role in suppression the damage of these pests. Efficacy of some chemical insecticide formulations was studied against 3rd, 4th and 5th nymphal instars and adults of different species of grasshoppers at the region of Gharb El-Mawhoop, New-Valley governorate, Egypt by using micron ULVA sprayer (ULVA+), Knapsack mist blower fifed with micron air rotary cage (AU8000) and Knapsack mist blower (ordinary back motor). Mortality percentages were calculated after 24, 48 and 72 hrs post-treatment for chemical insecticide treatments.The results indicated that Knapsack mist blower fitted with micron air rotary cage (AU8000) was more effective against 3rd, 4th and 5th nymphal instars and adults of grasshoppers than micron ULVA sprayer (ULVA+) for all treatments. Cypermethrin, fipronil, and fenitrothion recorded more toxicity after 24, 48 and 72 hrs by using full doses more than half doses or quarter doses against nymphal instars and adult stages of grasshoppers, despite of that, the application with half dose give mortality percentages approximately as the full dose, which resulted in reduction of the amount of pesticides and declined pollution of environmental ecosystems, so it is preferable to use the half dose for saving money and low pollution.Conclusively, from this results it could be concluded that the pesticides used have been descendingly arranged according to the efficiency as cypermethrin> fipronil > fenitrothion at all the treatments REFERNCES Abdel-Fatah, T.A.

“…Mayya et al (2005) have stated that anthropogenic activities and pollution affected the grasshopper diversity in Dakshina Kannada District, Karnataka. Hence, the low species richness in Nungambakkam might be due to the anthropogenic activities and pollution since it is located inside the city where automobile pollution is more.…”

“…Some grasshoppers cause significant damage to tree seedlings (Joshi et al 1999) and agricultural crops. They are also important components of the food chain for many birds and mammals (Capinera et al 1997;Mayya et al 2005), and hence resource management practices that alter grasshopper population dynamics will affect several trophic levels in the food chain (Capinera et al 1997). Most grasshoppers are oligophagous and exhibit definite host preferences (Mulkern 1967), according to which grasshoppers are classified as grassfeeders (graminivorous), forb-feeders (forbivorous) or a mix of the two (ambivorous or mixed feeders) (Isely 1944).…”

“…The changing scenario in agriculture is affecting primary consumers like grasshoppers and thereby creating impacts for entire food webs, thus it is necessary to study the distribution of grasshoppers in relation to their habitats and host plants. Previous studies conducted by , Muralirangan et al (1992), Sanjayan et al (1995), Joshi et al (1999), Kandibane et al (2004) and Mayya et al (2005) have added information on grasshopper fauna of different regions of India. The present study was undertaken to record grasshopper fauna from different host plants…”
