Problems solved by technology

The inventors found that at present, the method of picking up the soil by hand (bring the collected soil sample back to the laboratory, spread it out little by little with tweezers or insect needles to find the overwintering larvae inside) is used to determine the number of overwintering larvae in the soil sample, which is labor-intensive. Time-consuming and inefficient, and there is a high rate of missed detection

Embodiment 1

[0046] 1. Take a soil sample of 1000g, first use a 1# sampling sieve (diameter 20cm, height 6cm, aperture 4mm, 304 stainless steel material) to sieve out the litter, fallen leaves and large gravel in the soil sample, and lay a black polymer under the sampling sieve. Ethylene plastic film (0.5m×0.5m, thickness 0.05-0.12mm, preferably 0.1mm) is used to receive the worm-infected soil samples sieved for future use.

[0047]2. Transfer the worm soil sample screened out by the 1# sampling sieve to the 2# sampling sieve (diameter 30cm, height 6cm, aperture 1.6mm, 304 stainless steel material) to sieve out the medium-sized gravel in the soil sample, and use the sampling sieve Lay a black polyethylene plastic film (0.5m * 0.5m, thickness 0.05-0.12mm, preferably 0.1mm) to receive the wormy soil samples that are sieved down for subsequent use.

[0048] 3. Transfer the worm soil sample screened out by 2# sampling sieve to 3# sampling sieve (diameter 30cm, height 6cm, aperture 0.45mm, pref...

Embodiment 2

[0052] 1. Take a soil sample of 1500g, first use a 1# sampling sieve (diameter 20cm, height 6cm, aperture 5mm, 304 stainless steel material) to sieve out the litter, fallen leaves and large gravel in the soil sample, and lay a black polymer under the sampling sieve. Ethylene plastic film (0.5m×0.5m, thickness 0.05-0.12mm, preferably 0.1mm) is used to receive the worm-infected soil samples sieved for future use.

[0053] 2. Transfer the worm-infected soil sample screened out by the 1# sampling sieve to the 2# sampling sieve (diameter 30cm, height 6cm, aperture 2mm, 304 stainless steel material) to sieve out the medium-sized gravel in the soil sample, and put it under the sampling sieve. Spread a black polyethylene plastic film (0.5m * 0.5m, thickness 0.05-0.12mm, preferably 0.1mm) to receive the wormy soil samples that are sieved down for subsequent use.

[0058] 1. Take a soil sample of 1200g, first use a 1# sampling sieve (diameter 20cm, height 6cm, aperture 5mm, 304 stainless steel material) to sieve out the litter, fallen leaves and large gravel in the soil sample, and lay a black polymer under the sampling sieve. Ethylene plastic film (0.5m×0.5m, thickness 0.05-0.12mm, preferably 0.1mm) is used to receive the worm-infected soil samples sieved for future use.

Abstract

The invention provides a method for separating overwintering larvae of pine needle sheath gall midges and its application. The separation method comprises: taking a soil sample to be inspected and placing it in a first sampling sieve to screen out litter and large gravel in the soil sample; The soil sample under the sieve is placed in the second sub-sampling sieve to sieve the medium-sized gravel of the soil sample; the soil sample under the sieve is placed in the third sub-sampling sieve to sieve the fine soil in the soil; The sieve was subjected to water-bath oscillation treatment; the third sampling sieve after the water-bath oscillation treatment was placed in clear water, and after stirring to remove floating matter, the larvae were picked up with a colander, and repeated until the larvae in the third sampling sieve were completely picked up. The separation method of the present invention can quickly separate and collect the overwintering larvae of the pine needle sheath gall midge from the soil, is simple and easy, does not require complex equipment, greatly saves manpower and material costs, significantly improves the detection speed and efficiency, and significantly reduces the missed detection rate , so it has good practical application value.

Description

technical field [0001] The invention belongs to the technical field of pest monitoring and prevention, and in particular relates to a method for separating overwintering larvae of pine needle sheath gall midges and an application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The codiplosis Japonensis Uchida&Inouye belongs to Diplera, Cecidomyidae, Thecodiplosis. important invasive pests. The larvae hide in the base of the pine needles and suck the juice of the leaf base, causing the base of the needles to expand and form galls, the growth stagnates, and gradually withers and falls off. After 2-3 years of continuous damage, the vigor of the host tree will be s...
