Artificial cultivation method for Anagrus nilaparvatae

Abstract

The embodiment of the invention discloses an artificial cultivation method for Anagrus nilaparvatae, and belongs to the technical field of insect cultivation. According to the method, Cyperus iria L.or Kyllinga brevifolia Rottb treated by eicosane is used as oviposition substrates for Nilaparvata lugens. The method specifically comprises the following steps that rice seedlings are prepared; the Nilaparvata lugens is fed; the oviposition substrates for the Nilaparvata lugens are prepared; the Nilaparvata lugens oviposits on the oviposition substrates; the Anagrus nilaparvatae parasitizes eggsof the Nilaparvata lugens; and the Anagrus nilaparvatae is released in a field. According to the artificial cultivation method for the Anagrus nilaparvatae, after the Cyperus iria L. or the Kyllinga brevifolia Rottb is subjected to spraying treatment with an eicosane solution with the concentration of 4.0 * 10<-5-> mol / mL, the oviposition amount of the Nilaparvata lugens on stems of the Cyperus iria L. and the Kyllinga brevifolia Rottb is remarkably increased; and compared with a rice seedling oviposition substrate, the artificial cultivation method for the Anagrus nilaparvatae uses the stemsof the Cyperus iria L. or the stems of the Kyllinga brevifolia Rottb pedicel as the oviposition substrates so that the risk that the Nilaparvata lugens are spread to the rice field can be effectivelyavoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of insect breeding, and in particular to a method for artificially cultivating Anagrusnilaparvatae. Background technique [0002] Rice planthopper is a pest in the family Delphacidae of the order Hemiptera. The common species include Nilaparvata lugens, Sogatella furcifera and Laodelphax striatellus, among which the brown planthopper is the most common species. Heaviest, followed by white-backed planthopper. [0003] The harm of rice planthoppers to rice is reflected in the fact that the sucking of rice juice can cause the loss of water and nutrients of rice, causing poor growth and even withering. In addition, rice planthoppers are also the vectors of various rice virus diseases, such as rice grassy dwarf disease, leaf dwarf disease and southern rice black-streaked dwarf disease, which bring double damage to rice. Rice planthoppers harm rice and cause a large amount of yield redu...

Problems solved by technology

However, the field population of the rice hopper has obvious dependence and lag on the field population of the rice planthopper, especially in the early stage of the rice planthopper outbreak, the natural population of the rice hopper is seriously insufficient Effective control of rice planthopper
