Effect of Nosema locustae on aggregation behavior of oriental migratory locust (Locusta migratoria manilensis)

SHI WangPeng, ZHANG Long, YAN YueYing, YAN YuHua(Institute of Plant Protection, China Agricultural University, Beijing 100094,China).  
The aggregation behavior of oriental migratory locusts (Locusta migratoria manilensis) infected by Nosema locustae was studied using a behavior bioassay and an electroantennograph (EAG). Third instar laboratory reared locusts were inoculated with Nosema locustae at a dose of 106 spores/individual. Pheromones were extracted from the feces and body of healthy locusts using dichloromethane. These crude extracts were purified and concentrated and then stored in a deep freeze until use. Locusts infected with Nosema locustae had a reduced sensitivity to the crude pheromone extracts and had decreased aggregation ability. The behavior bioassay demonstrated a significant reduction in aggregation behavior of the fourth instar females and fifth instars of both sexes. Overall, the effect of the crude extracts on aggregation of infected locusts is greater with males than females and is greater with older instars than younger instars. Analysis of EAG demonstrated a decrease in the electronic physiological activity of the infected adults. The reduction was particularly evident in infected females that had a significantly reduced EAG response to the feces of adult males and to the volatiles from eggs and the body of adult males. Infected adult males had a reduced response only to the feces of adult males. Infected locusts had a general reduced EAG response to the crude extracts from nymphs. Infected adults and 5th instar nymphs had a reduced response to the feces and body volatiles of the 4th instars and to the feces extracts of healthy 4th and infected 5th instars. But there was no marked difference in EAG response to the feces extracts from 5th instar females and 5th instar solitary locusts. These experiments demonstrate that when it is used to control locusts, Nosema locustae has significant behavioral effects. The conclusions are new evidences controlling locusts using Nosema locustae.
