摘要
试验依据CO_2能使储藏物害虫增加对PH_3的吸收,从而提高熏蒸杀虫效果的原理,通过组合不同浓度的PH_3与CO_2进行混合熏蒸防治椭圆食粉螨,并筛选出PH_3与CO_2混合熏蒸的最佳有效组合剂量,即PH_3剂量1～2g/m^3,CO_2浓度16％～32％。
According to the principle that CO2 could increase stored grain insects to absorb PH3 and improve fumigation effectiveness, the fumigation test with different combinations of CO2 and PH3 to control Aleuroglyphus ovatus (Troupeau) was carried out. The desirable effective combination was selected, i. e. AlP 1 - 2g/m3 and CO2 concentration 16 - 32%.
