在室内和温室条件下，测定了施氏线虫和异虫线虫对金甲甲虫（鞘翅目：金甲科）的潜在杀伤作用。异habditissp线虫的感染性幼体。与土壤混合浓度低至50 IJ /cm3时，Hp88菌株的防治效果为86%。随着线虫浓度的增加，对照没有增加。土壤表面施用浓度为160和640 IJ /cm2的线虫足以分别获得87%和86%的死亡率，即使在土壤表面以下40 cm的深度也是如此。TheHeterorhabditissp。菌株Hp88在25℃时对蛴螬的致病性最强。异性恋的控制水平较低，为30-47%。HL81应变,S。我感到很紧张。bibionisCR压力。nematodeHeterorhabditissp。BS菌株对昆虫死亡率无明显影响。然而，在16°C的温度下，heterorhabditissp .的HL81菌株。是最有效的。3 ~ 5周龄幼虫最易受感染。Hp88压力。在同样的实验环境下暴露于线虫的蛹没有受到影响。本研究的结果表明，m。菊属植物是昆虫寄生线虫生物防治的一个有吸引力的候选者。
The potential use of steinernematid and heterorhabditid nematodes against the beetleMaladera matridaArgaman (Coleoptera: Scarabaeidae) was determined under laboratory and greenhouse conditions. Infective juveniles (IJ’s) of the nematodeHeterorhabditissp., Hp88 strain, mixed with soil at a concentration as low as 50 IJ’s/cm3soil, resulted in 86% control. No increase in control was obtained with higher nematode concentrations. Soil surface application of the nematodes at concentrations of 160 and 640 IJ’s/cm2was sufficient to obtain 87% and 86% mortality, respectively, even at a depth of 40 cm below the soil surface. TheHeterorhabditissp. Hp88 strain was found to be the most pathogenic to the beetle grubs at 25°C. Lower control levels of 30-47% were achieved byHeterorhabditissp. HL81 strain,S. feltiae‘All’ strain and 5.bibionisCR strain. The nematodeHeterorhabditissp. BS strain did not have any effect on insect mortality. However, at a temperature of 16°C, the HL81 strain ofHeterorhabditissp. was the most effective. Grubs 3-5 wk old were found to be the most susceptible developmental stage of infection ofHeterorhabditissp. Hp88 strain. Pupae, which were exposed to the nematodes in the same experimental regime, were not affected. The results obtained in the present study suggest thatM. matridais an attractive candidate for biological control by entomoparasitic nematodes.
