How do chestnut manufacturers deal with chestnut kernel victims?

There are two common pests that harm chestnut, weevils and chestnut eating moths. They attack once a year, and their larvae eat chestnut meat. The adults of weevils appear from July to August. They pierce the chestnut fruit with mouthparts and produce eggs into the interior of the fruit. The larvae hatched from the eggs will grow by eating chestnut meat in the interior of the fruit; The adults of the chestnut eating moth appear from August to September. They lay eggs on the chestnut thorns, and the larvae hatched from the eggs decay into the chestnut eating, and grow by eating the chestnut meat. Yanshan red chestnut manufacturer suggested that the prevention and control measures should focus on prevention. The detailed measures are as follows:

1. Clean the garden and disinfect it. As weevils overwinter in the soil as larvae, chestnut moths overwinter in cocoons as larvae, and their cocoons are mostly bound in fallen leaves or weeds in the air. Therefore, collecting and burning fallen leaves and weeds in chestnut orchards in winter, digging deep into the soil, burying mature larvae in deep soil and pruning sick and disabled dead branches are the basic methods of prevention and control.

2. Insecticidal disposal. The harvested fruits are placed in a ventilated closed warehouse, spread about 70 cm thick, and fumigated with methyl bromide. The dosage is 40-50 grams per cubic meter of space, fumigated for 3-10 hours, or 1.5 grams of sulfur dioxide per cubic meter of space, fumigated for 20 hours. Some fruit agricultural pesticides, insecticides and other highly toxic pesticides are sprayed on chestnut thorns, which are easy to be poisoned when eaten by people. This method must not be taken.
