Problems solved by technology

However, the existing problems are that, on the one hand, entomogenic fungi are sensitive to the environment, and the control effect is not stable; on the other hand, there is a lack of suitable fungal pesticide application technology, and soil-dwelling insects live underground, so it is difficult to directly contact fungal spores and hair disease

Embodiment 1

[0026] This embodiment provides a device for trapping RIFAs infected with entomogenic fungi, the schematic diagram of which is attached figure 1 shown. Among them, 1 is the plastic upper cover, which is translucent and rainproof; 2 is the bottom box; 3 is a circular hollow place, where attractants are placed (to lure red fire ants); 4 is a ring-shaped carrier cut from cardboard, which is stuck with insect-growing fungi Conidia; 5 is a strip-shaped opening, the entrance and exit of the red fire ant.

[0027] The device is a disc-shaped plastic box, 5-10 cm high, 1.5-3.0 cm high; the plastic box is divided into two parts, the upper cover 1 and the bottom box 2, which are engaged with screw holes, the upper cover 1 is translucent, and the bottom box 2 is at the bottom. There is a ring-shaped filter paper sheet, the surface of which is coated with vegetable oil to adhere to the conidia of entomogenic fungi. The hollow part 3 of the filter paper sheet is used to place the RIFA at...

Abstract

The invention discloses a device for inducing pests to infect entomogenous fungi, which comprises a plastic box, wherein the plastic box comprises two engaged parts, namely an upper cover and a bottom box; a base plate is arranged at the bottom of the bottom box; a gap is formed on a side wall of the bottom box to just allow pests to pass; a hollow part is arranged in the middle of the base plate; pest inducers are arranged in the hollow part of the base plate; plant oil is coated on the surface of the base plate; and conidiospores of the entomogenous fungi are adhered to the surface of the plant oil. The device has a good effect of controlling red fire ants, and the conidiospores adhered to the surface of the plant oil in the device are conidiospores of Isaria javanicus P028 strains. Thedevice is reasonable in structure, safe and non-toxic, and effectively reduces wild population of pests in concentrated distribution in a safe mode.

Description

technical field [0001] The invention belongs to the technical field of biological control of pests, relates to a new application technology of fungal pesticides, and in particular to a device for controlling pests by using entomogenic fungi. Background technique [0002] Chemical pesticides are currently the most important method of controlling pests. However, the use of a large number of chemical pesticides not only has a high cost input, but also causes serious pollution to the environment. At the same time, due to the increase in the frequency of application and the increase in the amount of use, the pests are resistant to the pesticides. A great deal of research has been done on the biological control of pests. [0003] The current insecticidal devices all use synthetic insecticides. Synthetic insecticides are molecules without life and are not sensitive to the environment; fungal conidia themselves are a kind of biological cells, and biological insecticides are living ...
