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...
