Abstract
Desert Locust, Schistocerca gregaria (Forskål), is one of the important insect pests worldwide.
Chemical insecticides proved effective in controlling these locust, but with bad ecosystem impact.
This study evaluated the temperature stress on biorational insecticides against Schistocer
ca gregaria. Newly moulted 5th instar nymphs of the desert locust were feed on clover leaves
treated with LC50 of Azadirachtin, Rotenone, Sabadilla and Limonene. Also, anti-hormonal effects
of Precocene II showed decrease in protein; carbohydrate and lipid of haemolymph contents after
24hrs treatment of 5th nymph instar with these biorational insecticides. The higher LC50 was 3.4
obtained after treating 5th nymphal instar with azadirachtin, lower LC50 was 4.2 caused by limonene
with LC90 of 15.2 & 28.2% respectively. These biorational insecticides affected protein,
lipid and carbohydrate of 5th nymphal ones, added by temperature marked stress. Supernumerary
(extramoulted) nymph emerged after treating 5th nymph instar with Precocene II. Precocene II
caused nymph malformations at high concentration (33.3%; 1000ppm) and at low concentration
(14.2%; 50ppm), and blocked adult emergency with increased concentrations.
