Problems solved by technology

Because the insect has the characteristics of rapid development, strong reproductive ability and high degree of damage, the control effect on the yellow wild borer is not ideal at this stage.
[0003] At present, the control of the yellow borer is mainly chemical control, but it is harmful to the environment, humans and non-target organisms

Embodiment 1

[0031] A method to increase the proportion of females in the offspring of red-eyed wasps consists of the following steps:

[0032] Step 1 Preparation of egg cards: Preparation of egg cards from rice moth eggs;

[0033] (1) Rice moth egg rearing: the rice moth eggs are placed in the sterilized insect box, the temperature is adjusted to 20 °C in the bee breeding room, the relative humidity is 65%, and the natural light makes the eggs hatch into larvae;

[0034] (2) Rice moth larvae to adult feeding: the sterilized flour is added to the insect cage for the larvae to eat, the larvae pupate in the flour, when the flour in the insect box is less, add a layer of 3mm thick flour in time until the adults feather;

[0035] (3) Adult rice moth feathering to spawning: the feathered adult worm is transferred into a yarn mesh bag for them to mate and lay eggs, and a cotton ball dipped in 5% sucrose water is provided during spawning as a supplement for adult insects, and sucrose water is fed onc...

Embodiment 2

[0044] A method to increase the proportion of females in the offspring of red-eyed wasps consists of the following steps:

[0045] Step 1 Preparation of egg cards: Preparation of egg cards from rice moth eggs;

[0046] (1) Rice moth egg rearing: the rice moth eggs are placed in the sterilized insect box, the temperature is adjusted to 30 °C in the bee breeding room, the relative humidity is 70%, and the natural light makes the eggs hatch into larvae;

[0047] (2) Rice moth larvae to adult feeding: the sterilized flour is added to the insect cage for the larvae to eat, the larvae pupate in the flour, when the flour in the insect box is less, add a layer of 3mm thick flour in time until the adults feather;

[0048] (3) Adult rice moth feathering to spawning: the feathered adult worm is transferred into a mesh bag for them to mate and lay eggs, and a cotton ball dipped in 15% sucrose water is provided during spawning as a supplement for adult insects, and sucrose water is fed once a ...

Embodiment 3

[0057] A method to increase the proportion of females in the offspring of red-eyed wasps consists of the following steps:

[0058] Step 1 Preparation of egg cards: Preparation of egg cards from rice moth eggs;

[0059] (1) Rice moth egg rearing: the rice moth eggs are placed in the sterilized insect box, the temperature is adjusted to 25 °C in the bee breeding room, the relative humidity is 70%, and the natural light makes the eggs hatch into larvae;

[0060] (2) Rice moth larvae to adult feeding: the sterilized flour is added to the insect cage for the larvae to eat, the larvae pupate in the flour, when the flour in the insect box is less, add a layer of 3mm thick flour in time until the adults feather;

[0061](3) Adult rice moth feathers to spawn: the feathered adult worms are transferred into a yarn mesh bag for them to mate and lay eggs, and cotton balls dipped in 10% sucrose water are provided during egg laying as supplemental nutrition for adults, and sucrose water is fed ...

Abstract

The invention discloses a method for increasing the female ratio of Trichogramma progeny and its application. The specific process is to raise Trichogramma in the eggs of the alternative host, the rice moth, by setting a suitable breeding environment, host and parasitoid factors, without affecting On the basis of the quality of the breeding bees and the application effect, the female ratio of the offspring of Trichogramma is increased, thereby improving the effect of biological control of the yellow borer, which is conducive to the large-scale popularization and application of Trichogramma in the control of the white wood pest pest, the yellow borer. A large reduction in the use of chemical pesticides is of great significance to non-target biological safety, human health and ecological environment protection.

Description

Technical field [0001] The present invention relates to a technical method of controlling pests using red-eyed bees, more specifically to a method of increasing the female ratio of red-eyed wasps offspring and application thereof. Background [0002] Heortivitessoides Moore, a member of the Lepidoptera family Pyralidae, is one of the main pests of white wood. It is mainly distributed in the southern and coastal areas of China, including Yunnan, Hainan, Guangdong, Guangxi, Fujian and Taiwan provinces and regions, as well as India, Nepal, Sri Lanka, Australia and Fiji. Countries such as China, Malaysia and India have reported information that the yellow borer seriously harms white wood incense. Due to the rapid development, strong reproductive ability and great degree of harm of the insect, the control effect of the yellow borer at this stage is not ideal. [0003] At present, the control of the yellow borer is mainly chemical control, but it is harmful to the environment, humans ...
