摘要
在５种温度下，研究巴西豆象取食不同豆类对生长发育的影响。结果表明，巴西豆象幼虫取食小白豆、豇豆及菜豆后，生长发育及繁殖良好，内禀增长率较大且较接近。幼虫取食绿豆及饭豆后，能完成其生活史，但内禀增长率较小。大豆及豌豆不利于巴西豆象生长发育。
The development and reproduction of brazilian bean weevil Z.subfasciatus feeding onthe seeds of Phaseolus vulgaris,P.lunatus,P.angularis,V. sinensis,P.radiatus,Glycinemax and Pisum sativum were studied under 20,24,28,32 and 36℃. The innate capacityfor increase'r'and the finite rate of increase 'λ' were calculated as well.The resultsshowed not only that the development and reproduction were good but also that the rm andλ were relatively big and close to each other after feeding on the seeds of P. vulgaris,V.sinensis and P. lunatus. When the lavae feeded on the seeds of P. angularis and P. radia-tus,the weevil could complete life history,but the rm and λ were relatively small,G. maxand P. sativum were not in favor of the development of the weevil.
