T/JSEFA 006.2-2023 Guidelines for Monitoring and Integrated Control Techniques of Main Pests of Edible Mushrooms - Part 2: Flies (Musca) of Agaricomycetes

Scope

Main Technical Content: 4. Surveillance and Investigation 4.1 Adult Insect Attraction 4.1.1 Survey Time: When the environmental temperature exceeds 25°C, observe the number of adult insects attracted every week. 4.1.2 Attraction Method: Hang yellow sticky boards (with a double-sided size of 12cm × 20cm) at a height of 10cm–30cm from the mushroom cultivation surface in the mushroom shed/room, placing one board at each end and in the middle. Observe and record the number of attracted insects every three days after each survey, and replace the boards promptly after each survey. Refer to the morphological characteristics of edible fungus flea flies to record the number of adults. The survey results should be recorded in the "Surveillance and Investigation Record of Adult Insect Attraction of Edible Fungus Fleas", the format of which is shown in Table A.1. 4.2 Survey of Damage Situation 4.2.1 Survey Time: Conduct a survey once before the formation of primary mycelium in each spawning batch. 4.2.2 Survey Method: In the mushroom shed/room, use the five-point sampling method to extract 10 fungal bags and observe the larval damage on the mycelium surface of the bags. For grass-decaying fungi, select 10 samples of surface soil or culture medium with dimensions of 10cm (length) × 10cm (width) × 3cm (depth) according to the five-point sampling method to observe the larval damage at the sampling points. Record the number of larvae in each fungal bag or sampling point, and calculate the number of larvae and damage rate per bag or sampling point. Record the observation results in the "Survey of Damage Situation of Edible Fungus Fleas", the format of which is shown in Table A.2. 4.3 Recording of Farm Management Activities and Environmental Conditions Observe and record the cultivation management and pest and disease control during the mycelium growth and fruiting periods of edible fungi, as well as the temperature, relative humidity, and ventilation conditions i
