A team of researchers from Karadeniz Technical University, Turkey Marmara Research Center Food Institute and Ankara University, Turkey, evaluated the insecticidal efficacy of two entomopathogenic fungi, Trichoderma asperellum and Beauveria bassiana to control of Tribolium confusum alone or in combination with de novo zeolite formulations.

The bioassays were conducted at 20°C, 25°C, and 30°C temperatures and 55% relative humidity on stored wheat. Single characters contain of each fungus or zeolite formulation (Zeolite 4A-Ph8, Zeolite 800MSC, ECOZEO Project®) were applied at 400 ppm dosage rate alone, aside from binary combinations (FMC-008=T. asperellum+Zeolite 4A-Ph8; FMC- 009=B.bassiana+Zeolite 4A-Ph8, 6x109 UFC/gr).

Mortality was measured after 7, 14, 21, and 28 d of exposure. F1 progeny was recorded after 8 weeks. The mean mortality of T. confusum adults after 21 d of exposure considering all single and binary combinations were less than 50% , 80%, and 80% at the 20°C, 25°C, and 30°C temperatures respectively.
