Abstract

The invention relates to a device for determining growth and development indexes of whitefly parasitic wasps by using living plants and a use method. The device comprises a parasitizing device and a culture device. The parasitizing device disclosed by the invention comprises an upper parasitizing dish and a lower parasitizing dish, wherein opening faces of the upper and lower parasitizing dishes are formed oppositely, spongy cushions are separately arranged at joints, and thus, a space for parasitizing of the parasitic wasps is enclosed; 3 ventilation openings are separately formed in two sidefaces of the upper and lower parasitizing dishes, and an insect receiving port is formed in one end, close to a snapping opening, of the top of the upper parasitizing dish and is connected with an insect receiving pipe; and the culture device is a disc with a cover, a circular opening is formed in the center of the cover, and a piece of gauze is laid in the circular opening. According to the device and the use method, growth and development conditions of the whitefly parasitic wasps are observed by using the living plants, the device is relatively close to a natural environment, and determination data are more accurate.

Description

technical field

[0001] The invention belongs to the technical field of insect feeding, and in particular relates to a device for measuring the growth and development index of whitefly parasitoids by using living plants. Background technique

[0002] Whitefly, belonging to Hemiptera (Hemiptera) and Aleyrodidae (Aleyrodidae), is a class of small and serious herbivorous insects in agriculture. Whiteflies mainly use adults and nymphs to directly damage host plants by sucking the phloem juice of eating plants, and can also secrete honeydew, which induces the occurrence of mold diseases and pollutes plants; at the same time, whiteflies are important vectors for many viral diseases, such as tobacco Whiteflies can transmit a variety of viruses such as geminiviruses, causing the prevalence of host plant virus diseases. As an important economic pest, Bemisia tabaci is one of the main pests of tropical and subtropical protected areas and field crops. It is very easy to break out and c...
