Biocidal effect of bio art biological product against Caryedon serratus (Olivier, 1789), seed pest in peanut stocks in Senegal

In order to design an integrated pest management strategy, the insecticidal activity of the product BioArt on eggs and adults of Caryedon serratus (Ol.) was studied in the laboratory at different concentrations. The main results revealed that BioArt affected the survival of treated stages, depending on the concentration applied. It caused 44.44% embryonic mortality in C1 and C2 and 82.22% larval mortality in C1. This bioactivity is also expressed by a modification of the development times and an imbalance of the sex ratio in favour of females. The adulticidal activity showed mortality spread over time for all doses. The BioArt product showed a remarkable adulticidal efficacy of 100% mortality in C1, 83.33% in C2 and 86.66% in C3. A reduction in the fecundity of females treated with the C1 dose was also noted, as well as a balance in the sex ratio of survivors to treated adults. BioArt must be used to protect the groundnut stocks.
