Problems solved by technology
[0003] At present, the widely used inspection methods of ear peeling and soil panning have defects such as labor-consuming and time-consuming, difficult identification, high labor intensity, and high technical requirements. In the 2002 agricultural industry standard forecasting specification, only more than 10 samples can be limited, which is far from It cannot meet the needs of forecasting and prevention, so that in the actual prevention and control, there are often missed treatments and pesticide abuse, causing environmental pollution and food safety problems

Embodiment Construction
[0010] The method for detecting the number of wheat midges of the present invention comprises the following method steps:
[0011] (1) Ear picking in the field, during the peak period of larvae occurrence (10 days after wheat flowering to before the larvae come out of the wheat ears), in the field with a large insect population density, take samples at 5 points on a single diagonal line, choose 10 ears at each point, and put them in In the paper bag, bring it back to the room for systematic observation of the natural pop-up of midges after soaking in water, and wash the ears after 7 days to check the amount of residual insects in the ears;
[0012] ⑵. Water immersion test, put 50 ears of wheat ears to be checked into a plastic bag with a length of 40cm and a width of 30cm, pour 5 liters of clean water into them, and make them all immersed in clear water for at least 10 seconds, then take out the ears of wheat, pour the water in the bag Put the ears of wheat into a white or blu...

The invention provides a sitodiplosis mosellana number detection method including the steps of field spike picking, water immersion detection and spike washing detection, wherein the water immersion detection comprises the steps of placing a wheat spike having immersed in water into a plastic bag to make sitodiplosis mosellana automatically pop up, recording the number of the sitodiplosis mosellana in the water, and repeating the steps for multiple times; the spike washing detection comprises the steps of rubbing the wheat spike after water immersion detection in water, then recording the number of the sitodiplosis mosellana in the water, repeating the steps for multiple times to obtain the final total number of the sitodiplosis mosellana. The method not only greatly improves the sitodiplosis mosellana detection speed, but also increases the accuracy of survey data, has the advantages of visual observation, easy identification, convenience for counting, and fastness and accuracy, and achieves the purposes of improving economic benefits, ecological benefits and social benefits.
Description
technical field [0001] The invention relates to a method for detecting wheat diseases and insect pests, in particular to a method for detecting the number of wheat midges. Background technique [0002] Wheat midge is a major pest worldwide, and it is an important pest of wheat in my country. The larvae lurk in the chaff and suck the juice of the wheat grains that are being grouted, resulting in grains and empty shells. Wheat midge is a destructive pest with larvae that damage flower organs, seeds and or grains. It occurred rampantly in the early 1950s, reducing wheat production by 10% to 20% year-round, 40% to 50% in major occurrence years, and 80% to 90% in serious cases, and was once controlled. In the 80s of the last century, it rebounded in an all-round way. Due to the reasons of forecasting and prevention, serious losses were repeatedly caused. In 1994, the national occurrence area exceeded 2.67 million hectares. In 2005, the area infested with insects in Henan reac...
