Mosquitoes captured and the egg positive traps were counted and recorded every day. Results Comparing with the control group, yeast-generated CO2 could take a strong attraction to mosquitoes in the field (P.05), but had an adverse effect in laboratory. P. maximum infusion, tyre infusion and L-lactic acid dilution could not attract Aedes albopictus to oviposit in Mosq-ovitrap. The colour change of Mosq-ovitrap could not raise its attractant ability to mosquitoes, on the contrary, increase the probability of mosquito escaping from Mosq-ovitrap.
结果 实验室和现场的结果显示,酵母发酵产生的CO2在室内实验中没有增强诱蚊诱卵器的诱蚊效果,而在现场实验中却产生较好的诱蚊作用,实验组的诱蚊指数和诱蚊密度指数与对照组比较差异均有统计学意义(P.05);大黍叶、轮胎浸出液和乳酸稀释液在试验中未显示出吸引白纹伊蚊雌蚊产卵的能力;在改变诱蚊诱卵器杯身颜色的试验中,杯身上2/3变为黑色并不能提高它的诱蚊和诱卵能力,反而增加成蚊逃逸的概率。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.
