Control litchi stink bug by egg parasitoids

卵寄生蜂对荔枝蝽的控制作用

The spatial distribution pattern and sampling methods for the adult of litchi stink bug ( Tessaratoma papillosa Drury) are analysed with six species aggregation indices.

本文用6种聚集度指标研究了荔枝蝽成虫空间分布型和抽样技术。

During 1990-1993, systematic investigations on litchi stink bug were carried out, and its integrated control was conducted.

1990～1993年间，在桂西南的左江、桃城、浪湾和武鸣4个华侨农场的荔枝龙眼果园中，进行了荔蝽的发生情况调查和综合防治研究。

Therefore, the extracts of litchi stink bug scent gland could be used as a class of bio-pesticides, and it was necessary to do further research on screening its active substance.

可见，荔枝蝽臭腺提取物可以作为一类生物农药，有必要进一步对其进行活性物质的筛选等方面的研究。

To understand the biological activity of the scent gland extracts from litchi stink bug, the common pests and pathogens were used to test the insecticidal activity of scent gland extracts, and there has no report about this research.

为了解荔枝蝽臭腺提取物的生物活性，本文进行其杀虫活性及熏蒸毒杀作用机理的初步研究，该研究方向尚未见报道。
