Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.
Example 1 growth and development of the status of Dermatophagoides pteronyssinus
The growth and development of the predatory mites of the malaria sericata are subjected to 5 stages of eggs, young mites, protonymphs, nymphs and adult mites, wherein the male mites have no nymphs, the morphological characteristics of the mite states are shown in figure 1, and the growth and development conditions are shown in table 1. According to the conventional conditions of pest occurrence in grain depots, the trialeurodes vaporariorum is taken as a feed, the growth and development of the sargassum malabaricus under the conditions of different temperatures (24 ℃, 28 ℃) and relative humidities (65 +/-2%, 75 +/-2%, 85 +/-2% and 95 +/-2%) are researched, and basic data are provided for the breeding and propagation of the sargassum malabaricus.
The egg has a development period of 1.5d-3d, and is elliptical in shape of 133x 94 μm in size, changes to 143x 96 μm in shape at mid-term of development, and is milky white in color.
The young mites have 3.8-6.6 d of growth period, three pairs of feet and milk white color, and gradually molt to become protonymous mites after about 1-2 days of rest.
The original nymphs have a development period of 3.3d-5.7d, four pairs of feet and a light yellow body color compared with the former mite state.
The later nymph, the development period is 4d-5.4d, the body is longer and darker than the former mite state, only the female adult mite experiences the later nymph state, and becomes an adult mite after molting.
Female adult mites undergo three resting periods and become adult mites, and male mites only need to undergo two resting periods.
The large-scale feeding of the predatory mites of the malarial six-shell beetles is more beneficial to the control of natural enemies, and requires shorter life history, longer adult mite period (because the adult mite period is the period with the largest predation amount), and the highest oviposition amount. As can be seen from the table 1, the growth and development, the life history, the adult mite period and the total egg laying amount of each mite state are the best feeding conditions of the Pacific acid red mites under the conditions of the temperature of 28 ℃ and the humidity of 75 +/-2%, the life history of the female mites is 14 days, the adult mite period is 66 days, the maximum egg laying amount can reach 557 eggs, and the male mites are also in more ideal feeding and breeding conditions.

Example 5 prevention of Tetranychus malabaricus against Trionyx sinensis Wiegmann in farmer's barn filled with wheat
The rusted brown paddy steams are grain storage pests which frequently burst in grain depots, and are harmful in most provincial and municipal grain depots in China, and recent investigation finds that secondary pests are promoted to be main pests, the phosphine resistance of the secondary pests is enhanced, and the secondary pests are easy to burst repeatedly after fumigation treatment. The meat mites of the malabaricus have good control effect on the rust red paddy steamers, and are ideal natural enemy resources of the paddy steamers.
The method utilizes the Paliurus ramosissimus to control the stealing of the red and flat paddy caused in the farmer house with wheat, aiming at 2 farmer houses damaged by the stealing of the red and flat paddy, 1 ton of wheat is filled in the farmer house, the Paliurus ramosissimus is put in,
detecting the density of pests and mites by using a manual sampling method, wherein the main pests are the rusty brown paddy beetles, and the density is 10 heads/kg; the maximum estimation of 1 ton of wheat is about 10000 heads of rusty red flat grain steamers;
the farmer house is circular, 1.5 meters high and 1 meter in diameter, and 1 throwing point is selected at the center of the grain flour;
feeding Pachyrhizus equi (Pachyrhizus equi: about 1: 2) with wheat as matrix and Pachyrhizus equi as feed into a feeding point release box; the number of the thrown liquid is about 10000;
the humidity of the throwing environment is 40-60%, and the temperature is 20-28 ℃;
selecting the density of the pests and the predacious mites of the malabaricus, which are checked in a sampling mode every 20 days, monitoring the control effect, and detecting for 3 times in total;
control effect (%). 100-.
As can be seen from Table 3, the Panonychus malabaricus has a good inhibitory effect on the population density of the Thelephora scabrosus, and the control effect of the farmer house is on the rise after the Panonychus malabaricus is thrown in the farmer house and reaches 84% after 60 days of the throwing.
Through the measurement of the quality of the wheat before and after the prevention and treatment, the water content, protein, starch and wet gluten of the wheat are not obviously changed; meanwhile, no difference of the bacteria carrying amount of the wheat is found through the test of the bacteria carrying amount, which indicates that the quality of the wheat is not influenced before and after the Panonychus malabaricus is used for preventing and treating the rust red and flat Valley steatozoa.
