Insect growth regulating effects of neem extract and azadirachtin on aphids
      


Toxicity of a neem seed kernel extract (AZAL-S) was assessed under laboratory conditions against larvae of Culex quinquej fasciatus. The LC- value for AZAL-S was 0. 78×10-6. Exposure of 4th instar larvae to 0. 3×10-6 and 0. 5×10-6 AZAL-S for 120 hours caused 16.2% and 67.5% mortality re spectively . with various types of morphogenetic aberration. AZAL-S induced an obvious prologation of the larval period when 1st instar larvae were treated with 0. 1-1.0×10-6 AZAL-S for 7 days. The insect growth regulating...

在实验室条件下,测试了印楝种核提取物AZAL-S对致倦库蚊幼虫的毒力,其LC_(50)为0.78×10~(-6)。分别用0.3×10~(-6)和0.5×10~(-6)的AZAL-S处理致倦库蚊4龄幼虫120小时,死亡率为46.2%和67.5%,并出现各种畸形。用0.4×10~(-6)—1.0×10~(-6)的AZAL-S处理致倦库蚊1龄幼虫7天,发现其幼虫期显著延长。AZAL-S对蚊幼虫的生长调节作用与某些昆虫生长调节剂对蚊幼虫的作用相似。

The paper deals with biological control of stored-product insects.The methods include breed of insect-resistant varieties of plant, release of parasitic and predacious insects, release of sterile insects, application of IGR (insect growth regulate) and use of pheromones with pathalogical agent.

文章对生物方法防治储粮害虫进行叙述。该方法包括:培育抗虫作物(粮食)品种、释放寄生性和捕食性昆虫、不育昆虫的释放、应用昆虫生长调节剂,以及信息素和病原体一起使用。

On the basis of benzoylphenylurea larvicides and the molting hormones and their mimics, a series of 1-aroyl-4-aryl-2-t-butyl semicarbazides were synthesized. Their structures were characterized by IR, - 1H NMR-,MS and elemental analysis. The bioassay showed some target compounds had good insect growth regulating- activity. The quantitative structure-activity relationship have been established.
