Control Of Pulse Beetle, Callosubruchus Maculatus (F.) (Coleoptera: Bruchidae) In Different Cereals Using Spinosad Dust In Storage Conditions, Adel Khashaveh
Control Of Pulse Beetle, Callosubruchus Maculatus (F.) (Coleoptera: Bruchidae) In Different Cereals Using Spinosad Dust In Storage Conditions, Adel Khashaveh
Adel Khashaveh
Effectiveness of spinosad dust formulation, that contains 0.125% spinosad, was evaluated against adults Callosubruchus maculatus (F.) on four commodities: chickpea, split pea, cowpea and lentil. Spinosad was applied at three dose rates: 0.1, 0.2 and 0.3 g/kg, corresponding to 0.125, 0.25 and 0.375 mg/kg of the active ingredient, respectively. The experiment was carried out at 27°C and 55±5% relative humidity. Adults mortality was measured after 1, 2, 5 and 10-days of exposure. After the 10-day mortality count, all surviving insects were removed and samples retained under the same conditions for a further 35 days to assess progeny reduction. Mortality of …
Pathogenicity Of Iranian Isolates Of Metarhizium Anisopliae (Metschinkoff) (Ascomycota: Hypocreales) Against Trogoderma Granarium Everts (Coleoptera: Dermestidae), Adel Khashaveh
Adel Khashaveh
The Pathogenicity of Iranian isolates of Metarhizium anisopliae was evaluated against adults and larvae of Trogoderma granarium using immersion bioassay method. For each isolate, five aqueous suspensions were prepared in a logarithmic series from 1×105 to 1×109 conidia/ml. Each concentration was replicated four times. For each replicate, 30 adults or larvae were immersed in 5 ml of the suspension for 5 s. The entire assay replicated twice. All isolates were pathogenic to adults and larvae and mortality was elevated with increasing conidial concentration. Significant differences were detected among fungal isolates at different conidial concentrations. The cumulative mortality 10 days after …
The Use Of Entomopathogenic Fungus, Beauveria Bassiana (Bals.) Vuill. In Assays With Storage Grain Beetles, Adel Khashaveh
The Use Of Entomopathogenic Fungus, Beauveria Bassiana (Bals.) Vuill. In Assays With Storage Grain Beetles, Adel Khashaveh

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 conidia g-1) was evaluated against adults of Tribolium castaneum, Sitophilus granarius and Oryzaephilus surinamensis. The experiments were carried out at the rates of 0, 250, 500, 750 and 1,000 mg kg-1 and exposure intervals of 5, 10 and 15 days, in 24±2°C and 50±5% …
