Red illumination method for prompting mating and oviposition of artificially bred dichocrocis punctiferalis

Abstract

The invention discloses a red illumination method for prompting the mating and oviposition of artificially bred dichocrocis punctiferalis. The method specifically includes the following steps that: temperature in an insectary is controlled in a range of 24 to 26 DEC C, and relative humidity in the insectary is controlled in a range of 40 to 60%, and a common fluorescent lamp is adopted to provide a light source, so that the alternation of day and light can be controlled, and the ratio of the illumination duration of the day to the illumination duration of the light is 15:9; 15% sucrose water is provided for supplementing nutrition for the adults, an apple wrapped with medical gauze is suspended at the top of a cage so as to provide a place for the oviposition of the females; the gauze can be taken off regularly, so that ovums can be obtained; the interior of the insectary is regularly disinfected and is kept ventilating; and in the dark period of a light cycle, a red fluorescent lamp is adopted as a light source, and the fluorescent lamp is suspended right above the cage by 10cm, and the illumination intensity of the four corners of the bottom of the cage is not lower than 2lux assuredly, and illumination time lasts for 9 hours assuredly, namely, red illumination is always provided in the dark period. According to the method, red illumination is provided in the breading period of the adults so as to simulate the natural spectrum at dusk and dawn, and therefore, the dichocrocis punctiferalis can be promoted to mate and oviposit, and breeding effects can be improved. The method is worthy of promotion and use.

Description

technical field [0001] The invention relates to a research method of pest prevention and control technology, in particular to a red lighting method for promoting the mating and egg laying of artificially reared peach borer moth. Background technique [0002] The premise of pest control technology research is to artificially raise pest populations indoors. Peach borer is widely harmful in agricultural production. In the process of indoor artificial breeding of this insect, many methods have been tried but the breeding effect is not good. In indoor pest rearing, mating and oviposition efficiency of adults are important parameters affecting subculture. In order to improve the feeding effect, the existing reported technologies usually adopt methods such as optimizing the feed formula of the larvae and adjusting the temperature and humidity of the insect breeding environment. In terms of lighting, the day / night length is only controlled by fluorescent lamps. The above methods h...
