Prepupae, pupae and newly emerged adults were treated with spore suspension of P.farinosus （1 ~ 10s conidia/mL）. Another group of adults were reared on sprayed poplar leaves with a same concentration of conidial suspension. Eggs production and hatching percentage were monitored daily over a 7-wk period. Overall reproductive capacity was significantly lower as compared with control. The total number of eggs per surviving female was 85.50, 149.50, 123.43 and 280.24 eggs for pre-pupa, pupa, adult and leaves treated, respectively as compared with 299.75 in control after fourth week. Pre-oviposition, ovipostion, post-oviposition days and the longevity of females and males were shorter in treated individuals compared with control. The lowest percentage hatching was 75.12% in eggs deposited by adults feed on treated leaves as compared with 98.42% in control.展开更多
