Abstract Psocids are damaging stored-product pests. In this study, eggs and early-instar nymphs, adults, all life stages of Liposcelis entomophila, L. decolor, bostrychophila, paeta were subjected to 43, 50, or 75% (Control) relative humidity (RH) for 2, 4, 6, 8, 10, 12, 14, 16 d at 30.0°C. All adults these species died within 8 both 43 50% RH, except which required 12 RH 100% mortality occur. ...

The insect growth regulator methoprene was evaluated for control of Liposcelis bostrychophila Badonnel, Liposcelis decolor (Pearman), Liposcelis entomophila (Enderlein), Liposcelis paeta Pearman (Psocoptera: Liposcelididae), and Lepinotus reticulatus Enderlein (Trogiidae) at application rates of 1, 5, and 10 ppm on maize, wheat, and rice. Methoprene did not completely suppress progeny productio...
