绿色金龟子Cotinis nitida（L.）通过田间试验和室内选择试验，测定了不同有机肥对成虫和幼虫的影响。将SIS有机肥处理（低肉鸡凋落物率，高肉鸡凋落物率，母猪粪便，干草，Milorganite或不施肥[对照]）施于砂壤土，并暴露于2.7 × 3.7 × 2.4 m筛笼中的成虫。更多的鸡蛋和幼虫被发现在盆处理肉鸡凋落物（43%），牛粪（23%），干草（30%）比盆处理Milorganite（4%）或无肥料（0%）。在Y型管和卫星嗅觉仪中测试了三龄幼虫的定向偏好。ave处理（肉鸡垫料，牛粪，干草，Milorganite，和空白对照），偏好是最大的肉鸡垫料和牛粪，但所有的有机肥处理通常优于空白对照。这些实验表明，使用有机肥料可能会导致更高密度的绿色六月甲虫幼虫既吸引产卵的女性，并作为一种食物引诱剂的移动的幼虫。
Relative preferences of green June beetle, Cotinis nitida (L.), adults and grubs for different organic fertilizers were determined in field and laboratory choice experiments. Sis organic fertilizer treatments (low rate of broiler litter, high rate of broiler litter, sow manure, hay, Milorganite, or no fertilizer [the control]) were applied to sandy-loam soil and exposed to adults in 2.7 by 3.7 by 2.4-m screen cages. More eggs and larvae were found in pots treated with broiler litter (43%), cow manure (23%), and hay (30%) than in pots treated with Milorganite (4%) or no fertilizer (0%). Orientation preferences of third-instar grubs were tested in Y-tube and satellite olfactometers. Of the ave treatments (broiler litter, cow manure, hay, Milorganite, and a blank control), preference was greatest for broiler litter and cow manure, but all organic fertilizer treatments were generally preferred over the blank control. These experiments suggest that use of organic fertilizers may result in higher densities of green June beetle grubs both by attracting the ovipositing females, and by acting as a food attractant for the mobile larvae.
