Abstract
綠豆象切蟲之嗜好豆類，以紅豆及綠豆最為嗜好，被害最為嚴重，大豆、青皮豆之被害較輕，豌豆、烏豆、花生仁等似不受其害。該蟲之防治方法雖多，但在本省環境下，當以採用豆類混拌粉劑，即在倉庫貯藏期間或至批發各地出售時期，均可獲得理想之治蟲效果。
本試驗計有粉劑 : Bromodan、Alodan、Premium malathion、Malathion、Lindane等五種，對綠豆象孵化幼蟲之接觸毒殺效力，以Bromodan與Alodan 粉劑之殘毒治蟲效力為最佳，Lindane粉劑次之，Malathion與Premium malathion為最短。
豆類混拌粉劑之適當施用藥量，切勿以經濟著想，而使用低濃度，以免日後發生害蟲對藥劑產生抗毒性，致失藥劑治蟲之能力，故應選擇較高濃度為優。在豆類收獲後可用5% Bromodan或5% Alodan粉劑任選一種，與豆類每千公斤使用粉劑0.4~0.5公斤混拌，即可達到治蟲目的，同時並可防止其他貯藏害蟲之發生。
Callosobruchs chnensis Linne is a serious pest of beans. The damage caused by the beetles on red beans, green beans, green soy beans, peas, black beans and peanuts have been observed. Red beans and green beans are comparatively heavy infested by the pest; soy beans and green soy beans are slightly infested. It seems that no infestation have been done by the beetles on peas, black beans and peanuts according to the observation.
Many methods can be employed for green bean beetle controlling, the treatment of chemical impregnated dusts would be the best under Taiwan’s environment, both in storage house or at whole sale market.
Bromodan, alodan, premium malathion, malathion and lindane have been used in the tests. Bromodan and alodan are highly effective contact poisoning for newly hatched green bean beetles, lindane the next, malathion and premium are effective only within a very short period. Either 0.4 to 0.5 kg of 5% bromodan or 5% alodan impregnated with 1,000 kg of beans can keep green bean beetles away from beans as well as other storage grain pests.
Low concentrations of the insecticides are not recommendued though they cos less money. Because the resistance varity will be built up rapidly.
