Control of Sitophilus zeamais (Motsch) [Coleoptera: Curculionidae] on Sorghum Using Some Plant Powders
Plant powders prepared from five plant species were tested under constant conditions at 30 ± 2°C and 60 65% r. h. for their ability to protect sorghum grains against Sitophilus zeamais in storage. Doses at 0.5, 1.0 and 2.0g and 0.12g of the check (permethrin (0.6%) were applied for assessments of adult mortality, emergence and damage. Leaf powders of E. balsamifera, J. curcas and L. inermis gav...

متن کاملBioactivity of diatomaceous earth to Sitophilus zeamais (Coleoptera: Curculionidae) in different application conditions
The objective of this study was to evaluate the insecticidal activity of diatomaceous earth (DE) at different ambient temperatures on adult Sitophilus zeamais and progeny, using different doses and exposure periods. The experiments were performed in Petri dishes containing 40 g of the whole corn kernel, treated with DE at doses of 0, 0.25, 0.5 and 1.0 kg Mg-1. Each dish was infested with 25 S. ...
متن کاملFlight activity of Sitophilus oryzae (L) and Sitophilus zeamais Motsch (Coleoptera: Curculionidae) and its relationship with susceptibility to insecticides.
Insect-pest mobility can influence insect susceptibility to the insecticides used to control them. The objective of this work was to evaluate the flight activity of Sitophilus oryzae (L) and Sitophilus zeamais Motsch populations reared on corn and wheat grains, and its relationship with insecticide susceptibility. Unsexed adult insects with ages between 10 and 20 days were placed on a plastic t...
