伊藤厚丝叶蜂生物学特性及其防治技术 总被引:3,自引:0,他引:3
伊藤厚丝叶蜂(Pachynematus itoi)在延边地区1a最少发生2个世代,以第2世代对落叶松危害严重。用40%辛硫磷喷雾、5%来福灵喷烟、20%杀铃脲喷雾防治伊藤厚丝叶蜂效果较好。 相似文献

大腹圆蛛(Araneus ventricosus)在吉林省2年完成1代,跨3个年度,以1-2龄和6-7龄若蛛越冬。该蛛除卵期及1、2龄蛛外,其它龄态的若、成蛛均张网捕食生活。该蛛喜居有光的栖境,在林缘、林窗处、路旁处结圆形垂直网,昼伏夜出,在小雨条件下可以正常活动。大腹圆蛛对小型猎物可直接取食,对中、大型猎物,需缠绕成束的捕获丝缚住再取食。在林间大腹圆蛛可取食多种蛾和叶蜂成虫,包括兴安落叶松鞘蛾、落叶松毛虫、黄褐幕枯叶蛾、舞毒蛾、栎毒蛾、松皮小卷蛾、松廮小卷蛾、伊藤厚丝叶蜂和落叶松叶蜂等多种落叶松害虫,是一种有效的害虫天敌。 相似文献

The presence of a natural enemy in a habitat refuge is no guarantee of emigration by these into crop fields, when pest population outbreaks occur. Parasitoids from a refuge may not prefer foraging on the pest crop, exhibiting host fidelity, and therefore not constituting a source of natural enemies for improving biological control. An effective refuge must not only be a suitable sink for natural enemies, providing an acceptable host when these are not present in the crop, but it must also be a suitable source of parasitoids that readily accept the aphid-host on the crop. Therefore, crop-originated parasitoids would have to accept pests from the refuge as hosts to lay eggs in, and refuge-originated parasitoids would have to accept and lay eggs in pests from the crop. We here study the host fidelity of populations of Eriosoma lanigerum originating from two host plants (firethorn and apple) through reciprocal transfer experiments. Thereafter, the host fidelity of parasitoids from populations in the two host plants (firethorn and apple) was assessed. Reciprocal transfer experiments of parasitoids did not show an association between apple-originated parasitoids and their preference for any of the aphid hosts. Conversely, parasitoids from firethorn exhibited a higher number of attacks and in less time when aphids from apple were offered, suggesting a preference for apple-originated aphids. If future field work confirms these findings, firethorn could become an important management tool for enhancing biological control of woolly apple aphid in apple orchards, without being a substantial source of aphids. 相似文献
