A laboratory assay was designed to determine the insecticidal efficacy of Trichoderma harzianum Rifai and diatomaceous earth (DE) against Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae: Bruchinae). The fungus T. harzianum was applied at 0.0, 3.3 × 10<sup>6</sup>, 6.6 × 10<sup>6</sup> and 2.1 × 10<sup>7 </sup>spores/kg of the common bean individually and mixed with 0, 200, 400 and 800 ppm of DE. The mortality counts were made after 1, 2, 4 and 7 days. All of the dead adults were removed after each count, and the vials were kept for the next 60 days to assess the emergence of any progeny. The highest mortality (93.88%) was achieved after 7 days using 800 ppm of DE and 2.1 × 10<sup>7</sup> spores/kg of T. harzianum and it suppressed emergence of the second generation after 60 days of treatment. These results concluded that DE can be used successfully along with T. harzianum against A. obtectus in stored common beans.

The common bean, Phaseolus vulgaris L., is one of the most important sources of protein in Ethiopia and other developing countries. However, the Mexican bean weevil, Zabrotes subfasciatus (Boheman), is a major constraint of stored common bean that causes qualitative and quantitative losses. This study was conducted to assess farmers’ knowledge and perceptions of Mexican bean weevil, to examine farmers’ pest management practices, and to identify challenges of pest management practices to develop integrated pest management (IPM) strategies. A survey of 148 smallholder common bean farmers was conducted at Mareka and Loma districts in southern Ethiopia. The majority (75%) of the farmers stored common bean in polypropylene bags while less than 10% of the farmers stored beans in ‘Diya’ (a traditional storage structure). Most (60.8%) farmers stored their beans in seed (threshed) form, and the majority (63.5%) of them stored their beans for 3-5 months. The majority of the farmers had knowledge about the Mexican bean weevil; they could identify damaged seeds based on the ‘holes’ on the seed (72.3%) and circular ‘windows’ on the seed (20.0%). About 45% of the farmers mentioned the high amount of loss at the time of storage. In addition, most farmers (53.4%) estimated 26-50% loss in storage. Most farmers reported the use of pesticidal plants for control of Mexican bean weevil, while only a few farmers reported they had applied insecticide in their store. Education level and family size had a positive and statistically significant impact on the use of pesticidal plants for the control of Mexican bean weevil. Furthermore, education level also influences the use of chemical insecticide. Results highlighted the need to use improved storage technology and to train farmers in postharvest handling practices as a component to develop IPM approach in order to minimize losses occurring along the value chains of the common bean.
