漆黑寡节鳃金龟(Heteronyx Piceus Blanchard)(鞘翅目,金龟子科)是为害花生的重要害虫。其幼虫在土壤中,可嗅到4～6cm远处的食物,并向有食物方向爬动,一旦发现食物后,就聚集在食物周围不再向别的地方移动。该幼虫对食物具一定选择性,最喜欢吃胡萝卜,花生幼根,其次是花生仁。表面襄有绿僵菌抱子粉的胡萝卜,花生油。对绿僵菌孢子粉既不回避,又不很喜欢。用大培养皿作金龟子幼虫取食行为研究的方法首次被使用。 Heteronyx Piceus Blanchard (Coleoptera, Scarabaeidae) is an important pest of peanut. Its larvae in the soil, can smell 4 ~ 6cm away from the food, and crawl to the direction of food, once found food, it gathered around the food no longer move to other places. The larvae have a certain selectivity of food, most like to eat carrots, peanut roots, followed by peanuts. Phytona fascicularis surface carrot, peanut oil. Metarhizium spore powder neither evade nor do not like it very much. For the first time, a large Petri dish was used as a study method for the feeding behavior of beetle larvae.
