Abstract

The potential of individual and combined treatments of two microbial insecticides, abamectin (AB) and emamectin benzoate (EM), and carbon dioxide (CD) for controlling Trogoderma granarium Everts on wheat grains was investigated. The effects of single and combined treatments on larval mortality after 7, 14 and 21 days, F₁ progeny after 30 days, F₂ progeny and weight loss of wheat after 80 days of treatment were measured. Results revealed that the mixtures of CD and two MIs were more effective in the controlling T. granarium than CD or MIs alone. The two mixtures, CD (40 %) + AB (1.0 mg/kg) and CD (40 %) + EM (1.0 mg/kg) achieved a maximum larval mortality (97.2 and 90.5 %, respectively) 21 days post treatment. Furthermore, AB alone and its combinations with CD caused a strong inhibition of emerged adults during two generations (≤ 1.0 adults). Treatments with EM produced the greatest decrease of adult production and the complete inhibition of F₁ and F₂ adult production when applied as the mixture of CD (40 %) + EM (1.0 mg/kg). Similarly, all MIs alone or their mixtures with CD caused a full protection of grains (weight loss ≤ 1.0 %) against khapra beetle damage for 80 days.

两种微生物杀虫剂与二氧化碳联用防治小麦储粮中木霉病的效果

研究了两种微生物杀虫剂阿维菌素（AB）和苯甲酸埃维菌素（EM）与二氧化碳（CD）单独和联合施用对小麦霉霉（Trogoderma granarium Everts）的防治效果。测定了单独处理和联合处理对小麦7、14、21 d后幼虫死亡率、30 d后F1代、80 d后F2代和体重下降的影响。结果表明，CD与两种MIs混合施用对小麦黑穗病的防治效果优于单独使用CD或MIs。CD (40%) + AB （1.0 mg/kg）和CD (40%) + EM （1.0 mg/kg）处理21 d后幼虫死亡率最高（分别为97.2和90.5%）。此外，AB单独及其与CD的联合对两代（≤1.0代）的出现成虫有很强的抑制作用。当CD (40%) + EM （1.0 mg/kg）混合施用时，EM对F1和F2成虫产量的抑制作用最大。同样，所有MIs单独使用或与CD混合使用均可在80天内对khapra甲虫的危害产生完全保护（体重减轻≤1.0%）。

期刊介绍： The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
