The potential for using spinosad to protect Australian grain from storage insects is discussed. Spinosad is produced from the metabolic by-products of a soil-dwelling bacterium, and is active against a range of insect species. Studies on relevant susceptible and resistant strains of a range of beetle and psocid pests indicate that spinosad efficacy varies greatly between species. Among the five...

This in vitro study evaluated the effects of crude alkaloid compounds extract plant A. majus leaves and flowers on some biological performance aspects insect. The results showed that at concentrations 10, 20 30 mg/ml significantly affected cumulative mortality different stages. concentration ( 30) had most noticeable effects, causing highest rate second fourth larval instars (86.7 73. 3 %, resp...

chemical insecticides have been widely employed for the control of storage grain pests. this has caused such problems as insecticide resistance along with contamination of foodstuffs with chemical residues. thus, there is a growing interest in using pathogenic control agents as alternative. in this study, the potential of beauveria bassiana (bbweevil™, a commercial product containing 2×109 coni...
