食虫

The results of the study on the occurrence, distrbution and natural control effect of fourteen parasitic wasps parasitized on two scales in Zhejiang citrus planting areas are presented. The results indicated that Microterys flovus How., M. ceroplastae Prirtsloo, M.sp and Metaphycus pulvinariae How. of Encyrtidae and Coccophagus iycimnia of Aphelindae are predominant, the rate of parasitism is 80-100%. If any one of the above mentioned five species of parasitic wasp is occurred in the orchard, the damage caursed by those two scales could be controlled.

本文对浙江桔区这两类蚧虫的14种寄生蜂的发生、分布及其天然制约作用进行了深入研究，以跳小蜂科的软蚧花翅跳小蜂、蜡蚧花翅跳小蜂、黑褐花翅跳小蜂、软蚧阔柄跳小蜂和蚜小蜂科的赖食软蚧蚜小蜂为优势种，寄生率高达80%～100%，在桔园只要有上述5种中任何一种寄生蜂存在，足以控制两类蚧虫为害。

However, the Cry1Ac-GFP fusion protein only accreted with peritrophic membrane of resistant strain and showed fluorescence, which suggested that the binding of peritrophic membrane with Cry1Ac toxin protein may result in resistance of larvae of H. armigera to Cry1Ac insecticidal crystal proteins.

比较Cry1Ac杀虫蛋白敏感和抗性棉铃虫幼虫中肠的发光部位，敏感棉铃虫幼虫的中肠围食膜已经消失，肠壁细胞发出强烈的荧光，而抗性棉铃虫的围食膜较健全并发出荧光。

Foreign gene could destroy larvas mid-intestine, and reduce its appetite. Observation by microscope showed that the gaps between mid-intestine cells was extended in treated larvae, and the nucleus were destroyed, the gap between peritrophic membrane and mid-intestine cells was appeared, parts of peritrophic membrane was broken off from mid-intestine cells.

外源基因对舞毒蛾幼虫的杀虫机理在于破坏幼虫的中肠组织，影响幼虫的取食，使幼虫取食量减少，甚至终止取食；中肠细胞间隙增大，细胞核遭受破坏；围食膜与中肠细胞之间出现空隙，甚至脱落，围食膜不再完整；中肠组织脱落，成为一个严重变形的残架。

Polyphaga may still hungry stomach fire Sheng; hunger and not for the Stomach-Yin Yu Shi insufficient; eat foreign bodies, such as raw rice, soil insects such as the plot.

多食仍觉饥饿为胃火盛；饥而不欲食为胃阴不足；嗜食异物，如生米、泥土等为虫积。
