Flight 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...
متن کاملCharacterisation of Response to Phosphine in Adults of Representative Strains of Sitophilus Zeamais (motsch.), Sitophilus Oryzae (l.) and Rhyzopertha Dominica (f.) from China
The effects of exposure period and phosphine concentration were quantified in adults of representative strains of Sitophilus zeamais (Motsch.), Sitophilus oryzae (L.) and Rhyzopertha dominica (F.) from China. All three species are major pests of stored grain in China. Although phosphine resistance is common in Chinese S. oryzae and R. dominica, with some very resistant populations, it is not pr...
متن کاملIdentification of species and geographical strains of Sitophilus oryzae and Sitophilus zeamais using VIS/NIR hyperspectral imaging technique
BACKGROUND: Identifying stored-product insects is essential for granary management. Automated, computer-based classification methods are rapidly developing in many areas. A hyperspectral imaging technique could potentially be developed to identify stored-product insect species and geographical strains. This study tested and adapted the technique using four geographical strains of each of two in...

متن کاملControl 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...
