摘 要：
The biological characteristics of Sericinus montelus were investigated in Shanghai during 2006-2007.It was found that the insect occurred for 3 generations annually and overwintered as pupa.The head capsule width of its larva at the lst,2nd,3nd,4th and 5th instar stagses was 0.07±0.01,0.13±0.02,0.22±0.04,0.34±0.05 mm and 0.45±0.06 mm,respectively.And correspondingly the development period of the larva was 2.14±0.38,3.43±0.53,3.57±0.97,2.42±0.54 d and 4.14±0.89 d,respectively.The duration of hunger tolerance of the 1st instar larva averaged 4.67±0.71 d.The total leaf amount eaten by the larva was 8 970.87 mm2 in leaf area.The lifetimes of female and male adults were 6.90±1.07 d and 5.57±0.98 d respectively.The sex ratio of female to male was 1∶1.43.The field tests showed that the corrected mortality of the larvae was 91.76%,91.23%,82.32% and 81.85% at 7 days after spraying respectively with 3 000-fold dilution of 2.5% Lambda-cyhalothrin,2 000-fold dilution of 2.5% Bcnzoy lphenyl ureas,3 000-fold dilution of 5% Chlorfluazuron,and 2 000-fold dilution of 1.8% Abamectin.
