Problems solved by technology

However, in the presence of alternate foods such as pollen, the population growth rate of these predatory mites increased, resulting in lower thrips populations and a corresponding reduction in plant damage

Embodiment 1

[0037] Embodiment 1, the predation potential of Neoseius spp. to Occidental flower thrips

[0038] This example compares and evaluates the local predatory mite Neoseiulus neoreticuloides Liang et Hu and two predatory mites widely used in production at present, Neoseiulus neoreticuloides (N. Predation potential of Amblyseius swirskii Athias-Henriot on Thrips occidentalis.

[0039] 1. The source of tested insects:

[0040] The three predatory mites tested are:

[0041] Neoseiulus neoreticuloides Liang et Hu, collected by Liu Qingyan et al. .cucumeris Oudemans) and Amblyseius swirskii Athias-Henriot, both are products of Fujian Yanxuan Biological Control Technology Co., Ltd.

[0042] In order to reduce the influence of food conditions in the past, the three predatory mites were fed with the same feed for several generations before the test, and then the experiment was carried out. Predatory mites were placed in an intelligent artificial climate box (PRX-350C, Ningbo Haishu Sa...

Embodiment 2

[0051] Example 2, Pollen as a food substitute for Neoseius spp.

[0052] The application of life table and its analysis method is an effective method to evaluate the control effect of natural enemies. This example studies the potential of N.neoreticuloides Liang et Hu, a local predatory mite species, to use two kinds of pollen as alternative food , to study its developmental duration and reproductive ability after feeding on pollen, and to construct the life table of the experimental population to evaluate the feasibility of using alternative food.

[0053] 1. Materials

[0054] The source of the tested insects: Neoseiulus neoreticuloides Liang et Hu, which was collected by Liu Qingyan et al. in June 2018 from the goji berry galls in the wild wolfberry fields of Uradqian Banner, Bayannao City, Inner Mongolia Autonomous Region. Place the source of tested insects in an intelligent artificial climate box (PRX-350C, Ningbo Haishu Saifu Experimental Instrument Factory) at 25 ± 1°C...

Embodiment 3

[0076] Embodiment 3, the large-scale breeding method of Neoseius spp.

[0077] In this example, the water tray method was used, and the sweet fruit mite was used to raise a large number of Neoseius spp. Specific steps are as follows:

[0078] Put a sponge with a length, width and height of 20x 14x 5cm in a fresh-keeping refrigerator box with a length, width and height of 30x 20x 10cm, and fill the box with water to 1 / 2 of the sponge. Then put the filter paper on the sponge, one side of the filter paper has no water to ensure its long-term wetness, and then put a black plastic film (about 15x10cm) smaller than the size of the sponge in the center of the filter paper.

[0079] Add sweet fruit mite (≥400 heads / g) mixed with feeding material on the black plastic film, and then add new Seiusius rugosa mite at a ratio of 100:1 between sweet fruit mite and predator mite. The feeding material is a mixture of sugar and yeast powder (the mass ratio of sugar and yeast powder in the mix...

Abstract

The invention discloses an application of Neoseiulus neoreticuloides Liang et Hu to control of small-sized juice-absorbing pests. The Neoseiulus neoreticuloides Liang et Hu is capable of controlling thrips and assistantly controlling whiteflies and pest mites, and particularly is capable of controlling Frankliniella occidentalis, Odontothrips loti, Bemisia tabaci(Gennadius), Aceria pallida Keifer,Tetranychus truncatus Ehara and Tetranychus urticae Koch. The Neoseiulus neoreticuloides Liang et Hu is easy in massive expanding propagation, thereby being beneficial to control of thrips in China and other small-sized juice-absorbing pests and colonization of natural enemies-predatory mites.

Description

technical field [0001] The invention relates to the application of Neoseius chinensis in preventing and controlling small sap-sucking pests in the field of biological control of agricultural pests. Background technique [0002] Western flower thrips (Frankliniella occidentalis), also known as western flower thrips (western flower thrips), belongs to Thysanoptera, Thysanoptera, Thripidae, and flower thrips is Frankliniella. In July 2003, for the first time in mainland my country, western flower thrips was found in the suburbs of Beijing to seriously harm peppers in protected areas, and it spread rapidly across the country. Moreover, it can also transmit a variety of viruses, and it is a worldwide invasive pest with devastating damage on various crops such as vegetables and flowers. [0003] Predatory mite is one of the most effective natural enemies known to control thrips, spider mites and whitefly. Neoseiulus cucumeris Oudemans (synonym Amblyseius cucumeris) has been used ...
