Several IGRs, including methoprene, triflumuron and flufenoxuron, have been shown to exert an ovicidal action in some insect species.
Mian and Mulla (1982a) compared the ovicidal effectiveness of triflumuron, diflubenzuron and methoprene on wheat flour and wheat at 5 ppm, using Oryzoephilus surinamensis, Tribolium castaneum, Rhyzopertha dominica and Sitophilus oryzae.
Mian and Mulla (1982a), found that diflubenzuron induced higher rates of oviposition in Tribolium castaneum and R. dominica compared with control samples; however, it also showed ovicidal activity against R. dominica,
The ovicidal activity of diflubenzuron was greatest in 0-4 in-old eggs.
Neem oil shows a strong ovicidal effect in bean-seed beetles (bruchids), but its sterilizing and other influences may also be important in controlling these pests, which constitute a major problem when storing beans of many types
