The current study evaluated the bio-control activity of Sudanese isolates entomopathogenic-fungi against 3rd larval instars Khapra beetle (Trogoderma granarium) (Everts) in Sudan and morphologically molecularly characterized virulent isolates. Fungi were isolated using Galleria-baiting method tested larvae immersion-technique at concentration 1×107 conidia ml-1. Commercial product, Eco-Bb...

Abstract In the present study we examined effect of presence wheat bugs ( Eurygaster spp. and Aelia spp.) on mortality, progeny production infestation patterns three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 5% relative humidity (r.h.) continuous darkness), 20 a...

Synthesis of bicyclic [1] and tricyclic [2] terpenoid lactones and the preliminary results of biological tests for their feeding deterrent activity [3] previously were presented. The tests, which were carried out on three storage pest insects: the grain weevil (Sitophilus granarius L.), the confused flour beetle (Tribolium confusum Duv.) and the khapra beetle (Trogoderma granarium Ev.), showed ...

Abstract The effect of four concentrations (0, 3, 1, 5%) the nanopesticide neem leaf extract was tested on stages hairy grain beetle at five time times (1, 2, 5, 7) days. results showed that there is Significant differences between three 5) compared to fourth concentration, which represents control treatment, where it noted hatching rate egg stage lowest 5% concentration. As for larva and pupal...
