ovicidal

Diflubenzuron applied to fishmeal at 1-3 ppm killed early instar larvae of D. maculates within 3-10 days of contact and appeared to be ovicidal at 5 ppm.

Chapter 7 1994

Several IGRs, including methoprene, triflumuron and flufenoxuron, have been shown to exert an ovicidal action in some insect species.

Chapter 7 1994

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.

Chapter 7 1994

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,

Chapter 7 1994

The ovicidal activity of diflubenzuron was greatest in 0-4 in-old eggs.

Chapter 7 1994

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

5 Effects on Insects 1992

(Ganesalingham, 1987.) · Biting flies Azadirachtin also exerts an ovicidal effect in eggs of the blood-sucking fly Stomoxys calcitrans.

7 Medicinals 1992

Unfortunately this chemical has no ovicidal properties, so that a second spraying was necessary to kill the mites newly hatched out from thousands of eggs.
