Pulse beetle, Callosobruchus chinensis is one of the major stored pests pulses. There were various factors that influence ovipositional behaviour C. chinensis. The preference host specificity for oviposition by female pest very important to lay maximum number eggs and also survival a species. Bigger size, smooth surface, deep coat coloured seeds are most suitable oviposition. combination temper...

Pollutants rarely occur alone in the natural environment, and few studies have focused on the potential interactions between metals or metalloids. In this study an aquatic insect, the southern house mosquito (Culex quinquefasciatus: Diptera), was used to test the individual and joint effects of dissolved sodium selenate (Se) and methyl mercury chloride (MeHg). We conducted ovipositional prefere...

BACKGROUND Anopheles gambiae s.s. Giles is a major malaria vector in Sub-Saharan Africa. Studies of the basic biology of this mosquito, including oviposition, provide a background for assessing which attributes might be exploited for suppressing A. gambiae populations. Here, we report on when during the diel cycle A. gambiae individuals deposit eggs as compared to the ovipositional patterns of ...
