Problems solved by technology

In the 1970s, researchers began to use entomopathogenic nematodes to control termites, which have the potential to be used as termite control agents. However, due to factors such as termite social behavior, physiological and biochemical defense responses, nematodes are not effective in actual termite control applications (Chouvenc et al. al., 2011; Al-Zaidawi et al., 2020)
Bacteria, viruses, fungi, nematodes, antibiotics, etc. can all be used for termite biological control. Among them, entomopathogenic nematodes have been used in termite control research reports at home and abroad, but the actual application effect is limited. The reason is that the termite behavioral immune defense mechanism is important one of the reasons

Embodiment 1

[0035] 1. The effect of α-terpineol on the survival and infection ability of nematodes

[0036] Add α-terpineol to the nematode suspension, so that in the mixed suspension of α-terpineol and nematode liquid, the nematode concentration is 200IJ / only (26667IJ / mL), and the concentration of α-terpineol is 1.163mg respectively / mL, 1.316mg / mL, 1.438mg / mL (denoted as LD10, LD20, LD30 respectively), placed in a dark incubator at 25±1°C for 7 days, observed every day, randomly took 100 μL nematode suspension for each repetition and counted The plates were checked for nematode survival under a stereoscope. The nematode suspension was used as a control. Calculation: Survival rate%=(number of living nematodes÷number of total nematodes)*100%. 3 replicates per treatment.

[0037] Pick 10 Mellonella mellonella larvae in a 9cm petri dish filter paper, drop 1.5mL of the nematode suspension treated with α-terpineol into each dish, place it in a dark incubator at 25±1°C for 48h and 72h, chec...

Abstract

The invention discloses a termite control medicine containing alpha-terpilenol and application of the termite control medicine. The termite control medicine contains alpha-terpilenol and entomopathogenic nematodes. According to the experiment, aiming at the most important harmful termite Copterus formosanus shiraki in China, alpha-terpilenol is utilized to interfere a termite immune defense system, and infection of an entomopathogenic nematode Steinema carpocapsa All strain is combined, so that the control effect of the entomopathogenic nematodes on the Copterus formosanus is improved, and the application of the entomopathogenic nematodes in green prevention and control of termites is further enhanced.

Description

Technical field: [0001] The invention belongs to the field of termite control, and in particular relates to a termite control drug containing α-terpineol and application thereof. Background technique: [0002] Termites are listed as one of the world's five major pests by the International Insect Physiology and Ecology Research Center, which can cause serious damage to various fields such as houses, buildings, reservoirs and dams, transportation and agricultural production, especially in tropical and subtropical regions (Huang Fusheng et al., 2000). Entomopathogenic nematodes (Entomopathogenic nematodes) are one of the important biological control measures, which have the characteristics of actively searching for hosts, broad insecticidal spectrum, and not easy to produce drug resistance. In the 1970s, researchers began to use entomopathogenic nematodes to control termites, which have the potential to be used as termite control agents. However, due to factors such as termite...
