The virulence of Isaria fumosorosea alone and integrated with an enhanced formulation of diatomaceous earth (diatomaceous earth + bitterbarkomycin, DEBBM) was tested against the lesser grain borer Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) under laboratory conditions on stored wheat. The fungus was applied to wheat grains at various concentrations of 3.60 × 106, 3.60 × 108, and 3.60 × 1010 conidia/kg alone, or in combination with 15 and 30 ppm of DEBBM. R. dominica was held at 20, 25 and 30°C and two RH regimes (56 and 75%) and mortality was registered after 5, 10 and 15 d. Generally, I. fumosorosea was most effective at 25°C caused the highest mortality of R. dominica at 56% RH. The increase of temperature, concentration and exposure interval increased the insecticidal effect of DEBBM at low RH level. The DE alone suppressed the progeny emergence at higher dose rate as compared I. fumosorosea alone, but their simultaneous use further reduced the progeny production of R. dominica. The integrated use of both tested bio control agents synergized the effect of each other and caused the highest mortality at 25°C and 56% RH. The results clearly demonstrated that I. fumosorosea and new enhanced DEBBM can be integrated to be an effective control measure for R. dominica in stored wheat.

Occurrence and diversity of entomopathogenic fungi in cultivated and uncultivated soils in Pakistan
Waqas Wakil,M. Usman GHAZANFAR,Tahira RIASAT,권용정,Mirza Abdul QAYYUM,Muhammad YASIN 한국곤충학회 2013 Entomological Research Vol.43 No.1
The distribution of entomopathogenic fungi in various geographical areas of Punjab, Pakistan, is poorly understood. The present study was planned to explore the occurrence and diversity of entomopathogenic fungi from soils collected from cultivated and non‐cultivated habitats. The detailed survey of different habitats (crop fields, fruits, vegetables, forests) was conducted to collect soil samples and the associated fungi were isolated using Galleria bait method. Among 210 soil samples, 168 fungal isolates were recovered and identified, with 98 from forests, 32 from vegetables, 30 from field crops and 8 from fruits. The major entomopathogenic fungi recovered from these samples were Beauveria bassiana, Metarhizium anisopliae, Paecilomyces lilacinus, B. brongniartii, P. chlamydosporia and Lecanicillium attenuatum. The diversity of entomopathogenic fungi was greater in soil samples from forests compared to crop fields, vegetables and fruits, respectively. The geographical attributes (altitude, longitude, latitude) greatly influenced the occurrence of entomopathogenic fungi with the highest number of isolates found from >600 m altitude, 33°–34′N latitude, and 73°74′E longitude from soil samples. The results of the surveys clearly indicated that the entomopathogenic fungi are distributed in the soils which may be used in successful IPM programs in future.

The utilization of diatomaceous earths (DEs) has been considered as a potential alternative to traditional in secticides for controlling grain storage insect pests. In this study, 19 different commercial DEs obtained from various regions of the world were evaluated for their effectiveness to manage Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), in vitro. Two different series of bioassays were carried out, with the first screening all 19 DEs and the second evaluating the eight most effective ones at different doses and exposure intervals for mortality assessment and progeny production. Four enhanced DEs, namely InertPMS, DEA, DiaHerb, and DEBBM were highly effective compared to other DEs tested. InertPMS exhibited complete adult mortality at 50 mg/kg, followed by DEA at 75 mg/kg, DiaHerb at 100 mg/kg, and DEBBM at 125 mg/kg, while GrainGuard exhibited 94.52 % at 125 mg/kg, 14 days post-exposure. Protect-It, SilicoSec, and DiaFil 610 were less effective at 400 mg/ kg, causing 87.3 %, 84.4 %, and 79.2 % mortality after 14 days, respectively. The offspring was suppressed in wheat treated with InertPMS at 75 mg/kg, while DEA, DiaHerb, and DEBBM revealed no progeny emergence at 125 mg/kg. GrainGuard, Protect-It, SilicoSec, and DiaFil 610 were not successful at progeny suspension after 62 days. These findings suggest that the use of specific DEs at low doses could be a viable option to mitigate the use of conventional insecticides and diminish the residues of insecticides on stored grains, making them the most feasible components for integrated pest management (IPM) in stored grain systems.
