Embodiment 1
[0067] Example 1: Pest control test in empty warehouse and mechanical equipment
[0068] 1. Method
[0069] 1. Application simulation method: powder drug film method
[0070] Powder drug film method: the washed culture dish (lower cover 70mm, cover 75mm) at 100°C for 2 hours, take out and cool, and stick a round filter paper with the same inner diameter on the inner bottom of the lower cover, pay attention to sticking firmly and compacting without leaving any gaps, so as to prevent the test insects from penetrating under the filter paper and affecting the test results. Then use a brush to stick an appropriate amount of polytetrafluoroethylene suspension and apply a layer evenly on the inner wall of the lower cover to form a smooth inner wall to prevent the escape of test insects. Then dry it at 60°C for 30 minutes, and take it out for later use. Use the weight gain method to weigh the test dose of the drug and place it in the prepared petri dish. After covering it, hold ...
Embodiment 2
[0084] Example 2: Control test of food anticaking agent silicon dioxide in raw grain and finished grain pests
[0085] 1. Method
[0086] 1. Application simulation method: powder mixed grain method
[0087] Dry and sterilize the cleaned cans (φ70mm×150mm) at 100°C for 2 hours, take them out and cool them for later use. For climbing pests, apply a 2cm-wide polytetrafluoroethylene tape on the upper part of the inner wall of the bottle to prevent the test insects from escaping, then dry it at 60°C for 30 minutes, and take it out for use. Weigh 100g of wheat with adjusted moisture (for powder-eating pests, add 0.5% groats with the same moisture content) and place it in a prepared can bottle, then weigh the test dose of medicament by weight loss method and put it in In a canning jar with wheat. Cover it with a cloth, tie it tightly with a rubber band, and shake the bottle for 5 minutes. After the suspended agent has completely settled down, you can get a well-mixed diatomaceous ...
Embodiment 3
[0113] Embodiment 3: Application test of food anti-caking agent silicon dioxide as insect-proof thread
[0114] 1. Method
[0115] 1. Apply indoor simulation
[0116] The cleaned stainless steel trays were dried and cooled at 80°C, and then according to different concentrations (60g / cm 2 、120g / cm 2 , 180g / cm 2 ) Weigh the corresponding quality of food anticaking agent silicon dioxide, and spread it evenly on the center of the tray through a grain sieve (Φ1mm) to make insect-proof lines with a width of 10cm, 15cm, and 20cm.
[0117] Put 10g of wheat on one side of the insect-proof line, and put the test insects on the other side, such as Figure 9 As shown, observe and record its passing through the insect-proof line. Put 20 test insects under the same conditions. After 24 hours, observe and record the number of test insects that pass, fail and stay on the food anti-caking agent silicon dioxide insect-proof line, and then observe and record the number of dead test insects ...
