Problems solved by technology

[0003] Due to the exotic nature of Moringa oleifera and the particularity of Moringa planting, the amount of Moringa oleifera infestation is large and frequent, and the frequency of application is high. The effect of traditional chemical pesticides on its control is getting worse and worse, and there is safety. Therefore, it is necessary to develop a new type of biological control method for this pest
[0004] Cantheconidea furcellata Wolff (Cantheconidea furcellata Wolff) belongs to the order Hemiptera, Pentidae, Eustinae, and the genus Cantheconidea furcellata. It mainly feeds on the larvae of some Lepidoptera and Coleoptera insects. Pronghorn bug will prey on Moringa moth

Embodiment

[0028] (1) Carry out the first generation of domestication and breeding:

[0029] In summer, adults and nymphs of Liriodont stinkbug were collected in the wild, and the adults and nymphs were separated, and the size was 40×40×40cm 3 The primary pupae of Tenebrio molitor and Moringa moringa were reared in the cages according to the routine, and potted fresh cabbage seedlings were placed in the cages at the same time.

[0030] (2) Carry out second generation induced breeding to produce the habit of predating on Moringa oleifera:

[0031] 10-12 hours after the adults lay eggs, take out the egg-laying block, place it on the leaves of potted fresh Chinese cabbage seedlings for hatching, the temperature is 28° C., the relative humidity is 70%, and the photoperiod is L:D=14h:10h.

[0032] As described below, the second-generation nymphs of the pronghorned stink bug after hatching were raised, and the temperature, humidity and light were routine.

[0033] Firstly, the hatched second...

Abstract

The invention relates to a breeding method and a use method of cantheconidea furcellata for preventing and controlling noorda blitealis, and belongs to the technical field of plant pest control. The purpose of the invention is realized by carrying out manual inducing feeding on cantheconidea furcellata and selecting a reasonable release density. Firstly, the first generation is domesticated and bred, and then inducing feeding is carried out on the second generation for generating the habit of preying noorda blitealis. The second generation of the cantheconidea furcellata is subjected to inducing breeding to becone three-instar, four-instar and five-instar nymphs or adults, and the nymphs or adults are directly released into a moringa oleifera forest for preventing and controlling the noorda blitealis. Plant leaves, filter paper sheets and culture dishes are placed at moringa oleifera branches with a large population density of the noorda blitealis, so that the diffusion and prey searching of cantheconidea furcellata larvae are facilitated. Each cantheconidea furcellata can prey about 21.04 noorda blitealis during the period of growing from a three-instar nymph to an adult, and hasstronger predation performance in an adult period, and the releasing amount can be determined according to the occurrence situation of the noorda blitealis in a field. The breeding method and the usemethod provided by the invention provide an effective biological preventing and controlling method for the damage of the noorda blitealis during the growth process of the moringa oleifera.

Description

technical field [0001] The invention belongs to the technical field of plant pest control, and in particular relates to a feeding method and a using method of the chrysalis for preventing and controlling the moringa moth borer. Background technique [0002] Moringa (Moringa oleifera Lam.), also known as Drumstick tree, is a perennial tropical deciduous tree. It is a commercial crop native to northern India. There are about 14 varieties in the world. In recent years, my country has introduced Moringa to the southern tropics and Cultivated in subtropical regions. Along with the expansion of Moringa plantation area, a kind of pest that has never appeared in my country, and specifically encroached on Moringa -----Noorda blitealis Walker also appears thereupon, and causes damage to Moringa plantation The losses are also getting worse. Moringa moth belongs to Lepidoptera family Crambidae. [0003] Due to the exotic nature of Moringa oleifera and the particularity of Moringa plant...
