Reduction of consumption by grasshoppers orthoptera acrididae infected with nosema locustae microsporida nosematidae



Reduction of consumption by grasshoppers orthoptera acrididae infected with nosema locustae microsporida nosematidae



Journal of Invertebrate Pathology 48(2): 232-238



The effect of ingestion of Nosema locustae Canning spores on feeding by grasshoppers was measured in simultaneous laboratory and field experiments. After 21 days, fourth-instar Melanoplus sanguinipes (F.) nymphs, administered spores at the rates of 0, 2.0 .times. 104, 2.0 .times. 105, and 2.0 .times. 106 per grasshopper, showed dry matter consumption of 102, 87, 64, and 26 mg in 48 hr, respectively. Rate of inoculation was a significant factor in suppression of feeding after correction for the effects of developmental stage, sex, and body weight. The quantity of dry matter consumed decreased linearly with increasing rate of spore ingestion. Experiments on 50 caged 1-m2 plots on pasture grass yielded similar trends in per capita consumption independent of the effects of mortality. Field consumption per integrated grasshopper-day was 108, 77, 31, and 27 mg dry wt at the four inoculation rates, over 20 days.
