昆虫保幼激素类似物双氧威处理小麦防治四种主要储粮甲虫的研究已进行了两年多,试验在模拟实际条件下进行,处理的小堆粮食约0.6吨,在0,6,12和18个月用赤拟谷盗、锯谷盗、谷蠹和谷象各300头进行感染。在药剂处理和害虫第一次引入后,每三个月取一次样,检查害虫情况、粮食品质及粮食中杀虫剂残留。另外还评价了粮食制粉和烘焙品质,测定了面粉、麸皮和面包中药剂残留。双氧威的效果通过与对照和甲基毒死蜱处理的粮食进行比较评价。甲基毒死蜱3.9mg/kg处理的粮食能防治锯谷盗9个月,谷蠹和赤拟谷盗12个月,谷象15个月。用双氧威4.2mg/kg处理的粮食能防治锯谷盗、谷蠹、赤拟谷盗2年,但对谷象不完全有效。双氧威8.2mg/kg处理的粮食能防治所有的四种害虫2年。粮食品质和面包制作品质在害虫数量较低时能较好地保持。甲基毒死蜱和双氧威的残留在面粉和制作的面包中很低,但麸皮中明显较高。
Insect juvenile hormone analogues of dioxide treatment of wheat four major grain stored beetle research has been carried out for more than two years, the experiment under simulated conditions, the processing of small heap of about 0.6 tons of food, 0,6,12 And eighteen months were infected with 300 tribes of Tribolium, sawtooth, thrips, and cereal. After pesticide treatment and pest introduction for the first time, samples are taken every three months to check for pest conditions, food quality and insecticide residues in food. In addition, the quality of food milling and baking was evaluated. The residuals in flour, wheat bran and bread were measured. The efficacy of diazepam was evaluated by comparison with control and food treated with chlorpyrifos. Chlorpyrifos 3.9mg / kg treated grain can prevent sawtooth 9 months, Valley beetle and red tarry 12 months, elephants 15 months. Diaoxiaowei 4.2mg / kg grain processing can control Sawatus Valley, Valley beetles, red tarry Pirates for 2 years, but not entirely effective for Valley. Dioxin 2 at 8.2 mg / kg treated grain could control all four pests for 2 years. Food quality and bread making quality are better maintained when the number of pests is low. The residues of methyl chlorpyrifos and dioxin are low in flour and bread, but are significantly higher in bran.
