Artificial feed for culex larvae and artificial breeding method

Abstract

The invention provides an artificial feed for culex larvae, a preparation method of the artificial feed and an artificial breeding method of the culex larvae. The artificial feed for culex larvae comprises the following components in parts by mass: 15-35 parts of chicken liver powder, 10-30 parts of shrimp feed, 5 parts of flour, 5 parts of fried bean flour, 5 parts of yeast powder and a certain amount of water. The preparation method comprises the steps of stirring, baking and water mixing. The breeding method comprises the steps of breeding preparation, larva breeding, observation and pupa separation. When the culex larvae are fed with the artificial feed, normal growth of the culex larvae can be met, the most ideal effect can be achieved, and therefore conditions are created for artificial feeding of the culex larvae. According to the artificial breeding method for the culex larvae, the technical problems of asynchronous development and the like in the breeding process of the culex larvae are solved, the normal growth and survival rate of the larvae are guaranteed, and a powerful guarantee is provided for large-scale production of laboratories and factories.

Description

technical field

[0001] The invention relates to the technical field of artificial feeding of insect larvae, in particular to an artificial feed and an artificial feeding method for Culex mosquito larvae. Background technique

[0002] As an emerging technology in pest control, sterile male insect release technology is used to reduce or even eliminate the insects by cultivating sterile male insects and releasing them to the breeding grounds of pests. After mating with wild female insects, they cannot reproduce offspring. Compared with traditional insecticide deworming strategies, this technology is environmentally friendly and has no impact on other insects and the environment. Culex mosquitoes can transmit diseases such as filariasis and Japanese encephalitis, and the "mosquito vector control" measures to control the number of transmitted viruses to reduce their contact with humans are of great significance.

Examples

preparation example Construction

[0031] A kind of preparation method embodiment 1-3 of artificial feed of the present embodiment, comprises the following steps:

[0032] Stirring: Mix chicken liver powder, shrimp feed, flour, fried bean powder and yeast powder according to the proportions of formula Ⅰ, formula Ⅱ and formula Ⅲ and stir evenly;

[0033] Baking: After being treated in an oven at 150°C for 20 minutes, cool naturally to room temperature for later use;

[0034] Mixed water: Mix the roasted artificial feed with water in proportion to form a suspension, and prepare a food turbid liquid with a concentration of 0.06g / ml to obtain the artificial feed for Culex mosquito larvae.

Embodiment 1-3

[0035] A kind of artificial rearing method embodiment 1-3 of Culex larvae of the present embodiment, comprises the following steps:

[0036] Breeding preparation: When the temperature is 26±1°C and the humidity is 80±10%, use a rearing tray with a length*width*height of 60cm*40cm*6cm, fill it with 4L of dechlorinated tap water, and the water depth is about 2cm.

[0037] Larva rearing: put the hatched Culex larvae into the feeding tray according to the feeding density of 3000 / pan and raise them. During the feeding process, raise them according to the formula of the artificial feed embodiment 1-3 of Culex larvae. Each formula Three sets of repetitions. According to Table 1, the artificial feed of Culex larvae was quantitatively added to the feeding tray every day until pupation.
