Abstract

The invention relates to a method for raising insect larvae of the genus Spodoptera. The method comprises the following steps: 1) hatching eggs of Spodoptera insects, feeding the hatched larvae with feed, and setting the environmental conditions as follows: the ambient temperature is 26 to 30°C, and the photoperiod is 3L:21D to 18L: 6D, the ambient humidity is 60% to 70%; 2) after the larvae grow to 4 instars, use the feed for single head feeding, and the environmental conditions are set as follows: the ambient temperature is 26 to 30°C, and the photoperiod is 0L: 24D to 15L: 9D, the ambient humidity is 60% to 70%.

Description

technical field [0001] The present invention relates to a method for raising larvae of Spodoptera insects, in particular to artificial feed for Spodoptera insects, more particularly to artificial feed for Spodoptera frugiperda. Background technique [0002] Spodoptera frugiperda Smith belongs to the order Lepidoptera, family Noctuidae, genus Spodoptera, commonly known as fall armyworm. Fall armyworm is native to tropical and subtropical regions of America. It invaded Africa and Asia in 2016 and 2018 respectively and spread rapidly. In January 2019, the insect invaded Yunnan Province from Myanmar and spread on a large scale. As of September 2019, noctuid moth has been found in 89 districts (counties) of 16 cities in Anhui Province. Spodoptera frugiperda has the characteristics of long-distance migration, wide host range, and strong reproductive ability. It causes serious economic losses on corn, sugarcane, sorghum and other food crops. It has spread to more than 20 provinces...
