摘要

[Objective] The paper was to study the growth and development characteristics of Callosobruchus chinensis L. on different beans,and to explore the resistance of different beans to C. chinensis. [Method] The egg hatchability,growth and development of larva and adult of C. chinensis L. on different beans were observed in the laboratory at 30℃. [Result]All the eight kinds of beans were spawned,but there were differences in egg hatchability among different beans. The egg hatchability on Vigna radiate was the highest of(78. 47 ± 6. 70) %. After hatching,larvae only drilled into grains of V. radiate,Vigna umbellate,Vicia faba,Pisum sativum and Cicer arietinum,but there were significant differences in generation survival rate. The generation survival rate on V. radiate was the highest of(68. 75 ± 9. 08) % and that on V. faba was the lowest of(26. 93 ± 10. 28) %. The development duration of C. chinensis on V. radiate was the shortest of(34. 78 ± 2. 02) d; the intrinsic rate of increase and finite rate of increase were greater of 0. 041 09 and 1. 041 95,respectively. [Conclusion]A large number of C. chinensis could be reproduced within a short period if feeding on V. radiate.
