Effect of Nomolt on Differential and Total Haemocytes in the Desert Locust Schistocerca gregaria Forskal (Orthoptera:Acrididae)
The insecticidal action of Nomolt at various dosages against Schistocerca gregaria was employed for its effects on total haemocyte count (THC)and differential haemocyte count (DHC). The total counts after application of different concentrations from Nomolt were significantly decreased at 1,3, 5 days on 5 nymphal instar and up to 1day old adult males and females comparing with those of the untre...
متن کاملThe vibrational startle response of the desert locust Schistocerca gregaria.
Substratum vibrations elicit a fast startle response in unrestrained quiescent desert locusts (Schistocerca gregaria). The response is graded with stimulus intensity and consists of a small, rapid but conspicuous movement of the legs and body, but it does not result in any positional change of the animal. With stimuli just above threshold, it begins with a fast twitch of the hindlegs generated ...
متن کاملEcdysone 20-mono-oxygenase in the desert locust, Schistocerca gregaria.
The enzyme catalysing the hydroxylation of ecdysone to 20-hydroxyecdysone, ecdysone 20-mono-oxygenase (EC 1.14.99.22), was investigated in the Malpighian tubules of fifth-instar locusts, Schistocerca gregaria. Enzyme activity was optimal at 35 degrees C and pH 6.8-8.0. Under these conditions the mono-oxygenase exhibited an apparent Km for ecdysone of 7.1 X 10(-7) M, a maximal specific activity ...
متن کاملDynamic flight stability in the desert locust Schistocerca gregaria.
Here we provide the first formal quantitative analysis of dynamic stability in a flying animal. By measuring the longitudinal static stability derivatives and mass distribution of desert locusts Schistocerca gregaria, we find that their static stability and static control responses are insufficient to provide asymptotic longitudinal dynamic stability unless they are sensitive to pitch attitude ...
متن کاملSulfakinins reduce food intake in the desert locust, Schistocerca gregaria.
In vertebrates, the peptides cholecystokinin (CCK), neuropeptide Y, galanin, and bombesin are known to be involved in the control of food intake. We report here that insect sulfakinins, peptides which display substantial sequence similarities with the vertebrate gastrin/CCK peptide family, significantly inhibit food uptake in fifth instar nymphs of the locust, Schistocerca gregaria. Upon inject...
