杧果小齿螟在广西南宁地区每年发生3代。幼虫蛀食果实造成为害。以蛹或老熟幼虫在树干裂缝内越冬。幼虫每年有2个为害高峰期。在x果生理落果基本停止时,用纸袋套果防虫效果达100%;在幼虫发育成熟期和采果后用石灰浆涂树干防治幼虫化蛹和越冬有很好的效果。在幼虫入果前或入果时,用菊酯类农药2500—3000倍液或菊酯类农药3000倍液与敌敌畏3000倍液混喷,防效在80%以上。
Mango small tooth borer occurs in Nanning, Guangxi area three generations each year. Larvae eat fruit damage. To pupae or mature larvae in winter cracks in the trunk. Larvae have two peak damage each year. When physiological decoction of x fruit basically stopped, the effect of pest control on paper bag was 100%. It is very effective to control larval pupation and overwintering by larvae coated with lime slurry in mature stage of larvae and picking fruit. Before the larvae into the fruit or fruit, with the pyrethroid pesticides 2500-3000 times or 3000 times the concentration of pyrethroid pesticides and 3000 times dichlorvos mixed spray, the control effect of more than 80%.
