Embodiment 1

[0047] Embodiment 1 A kind of high-efficiency breeding method of Trichogramma japonica

[0048] Include the following steps:

[0049] Step 1. Production of host eggs

[0050] a. Feed preparation: raw materials are mixed according to the following mass proportions: 70% cornmeal, 20% soybean flour, 10% wheat bran; 10 grams / kg of yeast is added to the mixed raw materials, and the above-mentioned feed is configured and placed in a container Stir it evenly and put it into the feed tray, put it into the disinfection cabinet for disinfection;

[0051] b. Larvae and adult rearing: put the sterilized feed into larval feeding boxes at a rate of 2.5 kg / box, the thickness of the feed is 3 cm, and evenly spread the rice moth eggs at a mass ratio of 1:1 000 (2.5 g / box) put into the sterilized feed; the environment of the larvae and adult feeding room should be controlled at a temperature of 24°C and a relative humidity of 70% for feeding, and the feeding room should be sterilized twice a ...

Abstract

The invention provides an efficient propagation method of trichogramma chilonis. The method includes the following steps of producing host eggs, preserving breeding bees, purifying and rejuvenating the breeding bees, inoculating the bees for parasitism, conducting culturing after parasitism, collecting the host eggs, and storing the host bees. The step of producing the host eggs include the substeps of preparing a feed, breeding larvae and adult insects, making the adult insects lay eggs, collecting rice moth eggs, and purifying and storing the rice moth eggs. By means of the propagation method, high-density rice moth breeding is realized, and the moth output of each square meter of breeding box can be ten thousands or above; compared with an existing method, 100 times of rice moths can beproduced in the same space. By means of the propagation method, the trichogramma chilonis has the parasitism rate of 92% or above and the eclosion rate of 80% or above.

Description

technical field [0001] The invention relates to a high-efficiency breeding method for Trichogramma japonica, belonging to the technical field of Trichogramma breeding. Background technique [0002] Trichogramma is a class of very useful insects. The Trichogramma that can parasitize the eggs of corn borer includes Trichogramma corn borer, Trichogramma pine caterpillar, Trichogramma japonica, and Trichogramma Tieling. Adults are less than 1 mm long, with pear-shaped wings, single wing veins and spike-like ciliates. Tarsus 3-segmented, conspicuous. Larvae parasitize moth eggs and are therefore used for biological control. The tiny Trichogramma, which can be easily bred in the laboratory, has been successfully used to control various Lepidoptera agricultural pests. [0003] CN200510002748.6 discloses a production method of Trichogramma artificial propagation, comprising the following steps: (1) Production of host eggs: selection and storage of tussah cocoons; heating of cocoo...
