在挖巢灭蚁的实践中,认识到黑翅土蚁巢群,随着巢龄的增加,主巢相应由浅入深变动。对于多腔中期以前的幼龄巢群,因巢系统入土不深,只要巢位判断准确,用人工挖巢的办法是比较容易的。但对于进入层裂期以后的成熟巢群,即使巢位判断十分准确,要把入土在1.5米左右的主巢取出,则既费工,又费力。为此,我们采用六六六和杀螟松烟剂自然压烟的方法处理黑翅土白蚁巢群,初步取得成效,现将结果整理,供参考。一、试材及方法1.试验材料:(1)六六六烟剂配方:60%六六六粉(重庆农药厂产)40%,硝酸铵35%,锯屑
In the practice of nesting and eliminating ants, recognizing the black-winged termites and nests, as the nest age increases, the main nest correspondingly changes from shallow to deep. For the multi-cavity medium-sized young nest before the nest system because the soil is not deep, as long as the nest to determine the accuracy of artificial nesting method is relatively easy. However, for the mature nesting group after entering the delamination stage, even if the nesting position is judged to be very accurate, it should be laborious and laborious to remove the main nest which is buried at about 1.5m. To this end, we use hexagonal and Pyreneescargot natural tobacco smoke method to deal with black-winged termites nest population, the initial results achieved, the results are collated for reference. First, the test materials and methods 1. Test Materials: (1) 666 formulations: 60% six six six powder (Chongqing Pesticide Factory) 40%, 35% ammonium nitrate, sawdust
