Embodiment approach 1

[0037] The different stocking density effect measurement of embodiment one:

[0038] (1) Gently pick 16, 24, and 32 newly hatched larvae into the rearing device with a hook pen, so that the larvae are evenly distributed as much as possible, and repeat 4 times.

[0039] (2) Add a sufficient amount of pea aphids evenly into the device, cover the petri dish cover 9, and seal along the seam of the petri dish cover with a parafilm (Parafilm), so as to prevent young larvae or nymphs from escaping.

[0040] (3) From the next day, add enough aphids every day, and increase the amount of aphids as the age increases until pupation, count and weigh the number of newly emerged adults.

Abstract

The invention relates to a breeding device and method for larvae of harmonia axyridis. The device specifically comprises a culture dish, a culture dish cover and a physical barrier device; the physical barrier device is placed in the culture dish and provided with an insect passing mechanism; the method comprises the steps of establishing a pea aphid population, breeding adult insects of harmoniaaxyridis with pea aphids, collecting eggs of harmonia axyridis, monitoring hatching of the eggs, newly adding aphids every day and breeding newly-hatched larvae until pupation. By means of the breeding device and method for the larvae of harmonia axyridis, the occupied space is small, intensive breeding of the larvae of harmonia axyridis is facilitated, and the breeding device and method are suitable for high-density larva breeding; the gathering degree and meeting possibility of the larvae are reduced in the breeding process, the autotomy rate is reduced accordingly, and the yield of productsof harmonia axyridis is increased; through intensive breeding, the production cost is reduced, the efficiency is improved, and the application and popularization of harmonia axyridis in biological prevention and control are promoted.

Description

technical field [0001] The invention belongs to the technical field of natural enemy insect artificial breeding, and in particular relates to a heterochromia larva breeding device and a raising method thereof. Background technique [0002] Biological control is an environmentally friendly pest control method, which plays an important role in reducing the use of chemical pesticides and improving the quality of agricultural products. In practical applications, effective biological control usually relies on large-scale release of artificially raised natural enemy insects, which requires efficient artificial large-scale breeding technology. Among them, scientific artificial breeding devices and application methods play an important role in improving the output rate of natural enemies, reducing production costs and saving labor. [0003] Heterochromia is an excellent predatory natural enemy common in my country. It has the advantages of omnivorous (can prey on a variety of pests...
