A vegetable oil-based biopesticide with ovicidal activity against the two-spotted spider mite, Koch.

A recently developed biopesticide made of safflower and cottonseed oils has excellent ovicidal activity against the hard-to-control spider mite Koch (Acari: Tetranychidae). It has attracted attention as a sustainable treatment for controlling because it has low potential for promoting resistance and little effect on the predatory mite (McGregor) (Acari: Phytoseiidae), which is an important natural enemy of spider mites. Here, we investigated the mechanism of its ovicidal activity against .
