貯蔵豆を害するマメゾウムシ類の産卵・死亡・発育に対する温度の影響

抄録

Influences of temperature on the number of eggs deposited, egg mortality, larval and pupal mortality, number of adults emerged, duration of developmental period and adult longevity of six different species of Bruchid infesting stored beans were studied under laboratory conditions. Callosobruchus maculatus was most resistant to high temperature, not only in oviposition but also in egg mortality and larval mortality. C. analis was the next. C. rhodesianus and C. phaseoli showed high mortality in the high temperature range. Zabrotes subfasciatus and C. chinensis were intermediate. The optimum range of temperature for oviposition, survival of egg and of the larvae was different for different species and different geographical strains, and showed the same order of differences with respect to high temperature resistance. Based upon the law of total effective temperature, point of developmental zero was estimated. It was 18°C or 17°C for C. maculatus and 13°C or 12°C for C. chinensis and C. phaseoli. C. rhodesianus, C. analis and Z. subfasciatus took intermediate temperatures. This order was almost the same with that of high temperature resistance.
