Bionomics of Callosobruchus maculatus Fabricius (Coleoptera: Chrysomelidae) in cowpea (host) and common bean seeds (non-host) were comparatively investigated in storage at ambient temperature (29.1°C) and relative humidity (73%) in Rivers State, Nigeria. Insect bionomics and concentrations of five toxic metals and five minerals were determined in cowpea and common bean varieties using standard methods. Results showed that the rates of infestation, development and damage by C. maculatus varied between the genus Vigna (cowpea) and Phaseolus (common bean) and within varieties of the same genus. It was possible to understand bionomics patterns of C. maculatus among the cowpea and common bean varieties; particularly observing that insects of the species C. maculatus do not feed in adulthood and do not develop in seeds of common bean, even when they were teased with very attractive seeds-brightly colored and mottled. The role of arsenic toxic metal in deterring C. maculatus bionomics and the roles of sodium, calcium and potassium minerals in making cowpea seeds susceptible to the beetle require more specific analysis. Interesting insect dynamics were observed and the new findings have implications for control of C. maculatus adults using thermal applications and oviposition-sensitive strategies. Temperature, relative humidity and surface texture affected C. maculatus performance. The adult C. maculatus preferred wet surface to dry surface and the mechanisms of orientation on surfaces were ortho and klino-kinetic reactions. This has implications for effective management of the pest by managers seeking to minimize seed damage and loss in stores.

在尼日利亚河州的环境温度（29.1°C）和相对湿度（73％）下，对cow豆（寄主）和普通豆种子（非寄主）中的Callosobruchus maculatus Fabricius（Coleoptera：Chrysomelidae）进行了生物学研究。使用标准方法测定了cow豆和普通豆品种的昆虫生物组学和五种有毒金属和五种矿物质的浓度。结果表明，C的侵染，发展和破坏的速度。黄斑在Vigna（co豆）和Phaseolus（菜豆）之间以及同一属的变种之间变化。有可能了解C的生物组学模式。黄斑在the豆和普通豆品种中；特别是观察到C物种的昆虫。斑不成年饲料和菜豆种子不发展，甚至当他们有非常吸引人的种子，颜色鲜艳和斑驳的戏弄。砷有毒金属在遏制C中的作用。斑生态学和的钠，钙和钾矿物质在使豇豆种子中的作用易受甲虫需要更具体的分析。观察到有趣的昆虫动力学，新发现对控制C具有重要意义。黄斑成人使用热疗和对排卵敏感的策略。温度，相对湿度和表面纹理的影响Ç。黄斑表现。成人Ç。黄斑优先选择湿表面到干表面，并且表面取向的机制是邻位和克林诺动力学反应。这对寻求最小化种子损害和储存损失的管理者的有害生物有效管理产生了影响。
