Natural biological control and key mortality factors of Diaphania hyalinata (Lepidoptera: Pyralidae) in cucumber
Biocontrol Science and Technology 13 (3), 361-366
Abstract: Key mortality factors due to natural biological control of the melonworm, Diaphania hyalinata, were investigated. Mortality factors were quantified in cucumber plots and used to develop a life table. The highest mortality of the melonworm took place during the egg stage (90.08% mortality) when the most important mortality factor was the predator Paratrechina sp. (Hymenoptera: Formicidae). However, the critical mortality stage of this insect pest was the fifth larval instar and its key mortality factor was parasitism by tachinid flies (aff. Amazohoughia, Eucelatoria sp. and aff. Lixophaga).
