棉花绿盲蝽在东营地区危害加重的主要原因是棉花与冬枣间作模式有利于其生长发育,加之抗虫棉大面积种植,农药用量减少,虫口密度进一步增加。调查结果显示,棉花绿盲蝽在东营一年发生5代,前两代危害最重,第1代危害高峰在4月下旬至5月上旬,... 棉花绿盲蝽在东营地区危害加重的主要原因是棉花与冬枣间作模式有利于其生长发育,加之抗虫棉大面积种植,农药用量减少,虫口密度进一步增加。调查结果显示,棉花绿盲蝽在东营一年发生5代,前两代危害最重,第1代危害高峰在4月下旬至5月上旬,第2代危害高峰在6月中旬,栆棉间作田重于单纯棉田。防治用药以氟虫腈、甲氰菊酯和马拉硫磷防治效果最好,用药后第3天防效分别为97.1%、95.3%和95.0%,用药后第7天防效分别为93.3%、87.3%和86.1%。 展开更多

The green mirid bug Apolygus lucorum is an agricultural pest that is known to cause damage to more than 150 plant species. Here, we report the transcriptomes ofA. lucorum at three different developmental stages (the second and fifth instar nymphs and adults). A total of 98,236 unigenes with an average length of 1,335nt was obtained, of which 50,640 were annotated, including those encoding digestive enzymes and cytochrome P450s. Comparisons with cotton bollworm and cotton aphid transcriptomes revealed distinct features ofA. lucorum as a mesophyll feeder. The gene expression dynamics varied during development from young nymphs to adults. The high-quality transcriptome data and the gene expression dynamics reported here provide valuable data for a more comprehensive understanding of the physiology and development of mirid bugs, and for mining targets for their control. 展开更多
