Coconut black-headed caterpillar mass propagation method

Abstract

The invention relates to a coconut black-headed caterpillar mass propagation method, which comprises the steps of performing feeding at all worm stages of coconut black-headed caterpillar under conditions of temperature of 25-27DEG C, relative humidity of 75 percent plus or minus 10 percent and natural illumination; pairing newly hatched male and female coconut black-headed caterpillar, introducing the coconut black-headed caterpillar into a glass pipe with old coconut leaves and providing honey water with concentration of 10 percent to supply nutrients, wherein the coconut black-headed caterpillar lay eggs on the coconut leaves after 1-2 days; picking out the leaves with the eggs and centrally putting the leaves into worm feeding boxes, wherein each box contains 1000 eggs; hatching the eggs for 6-7 days to obtain larvae and changing the leaves for one time at an interval of 4 days; realizing pupation after 50 days, obtaining young imagoes through eclosion of pupae after 9-12 days and entering a next cyclic breeding process. The coconut black-headed caterpillar mass propagation method has the advantages that since the old coconut leaves are used for feeding the larvae, the operation is simple, convenient and practical, the worms of the coconut black-headed caterpillar at all stages can be continuously, evenly and massively propagated, and a great number of worm sources are provided for the basic research, the prevention and the control of the coconut black-headed caterpillar.

Description

technical field [0001] The invention relates to a feeding and breeding method of insects, in particular to a mass breeding method of the weaver moth. Background technique [0002] Coconut Weaver Moth ( Opisina arenosella Wallker) is a new invasive alien pest in my country, belonging to Lepidoptera (Lepidoptera), Oecophoridae (Oecophoridae), coconut weaving moth English name coconut blackheaded caterpillar, Chinese translation has coconut blackhead caterpillar, leaf-eating caterpillar and coconut moth moth. Coconut weaver moth is an important pest on palm plants. In India, Sri Lanka and Myanmar, the coconut weaver moth is a serious threat to coconut trees. In recent years, the coconut weaver moth has spread to Thailand and Malaysia in the ASEAN countries, especially in Thailand, where the insect is seriously harmful. The pest feeds on the old and new leaves of palm plants, causing the leaves of the plant to dry up, defoliation, and even the death of the entire plant i...
