We examined how low levels of ambient oxygen influence the reproduction of the female cowpea bruchid (Callosobruchus maculatus), a pest ...

This study aimed to evaluate the yield and chemical composition of essential oils from Croton blanchetianus Sida cordifolia, in addition investigating insecticidal potential these on adults bean weevil, Callosobruchus maculatus. To obtain oils, hydrodistillation method was adopted, using a Clevenger apparatus. The identification quantification constituents performed by means gas chromatography ...
