Mung bean also known as bean cow, bean monkey, iron mouth, is a Coleoptera bean elephant, in the storage of grain warehouses and fields can be breeding harm, is the main pest mung bean storage period. Grains are often eaten, lost their ability to germinate, or even eaten.
First, the law of occurrence
One to six generations a year, larvae in the bean winter, the next spring eclosion into adults. The adults fly well, have a feign death, and live in groups. They lay their eggs in bean granaries in storage granaries and become adults 15 to 20 days later. It takes 24 to 45 days for a mung bean to complete a life cycle and develops fastest at 25 to 30°C and a relative humidity of 80%.
Second, control methods
1 Breeding resistant beans like mung bean varieties. The new mung bean variety, Jin Mung bean No. 3, developed by the Shanxi Provincial Academy of Agricultural Sciences, is highly resistant to mung bean, and is the first anti-bean cultivar currently grown in China.
2 chemical drug prevention and control method. When the amount of mung beans is small, aluminum phosphide can be put into a small cloth bag, put into mung beans, and sealed in a bucket for preservation. If the amount of storage is large, it can be stored in a sealed warehouse or in a fumigation chamber at a ratio of 1 to 2 pieces of aluminum phosphide per cubic meter. This will not only kill adult worms but also kill larvae and eggs without affecting them. Seeds germinate.
3 physical control method. After the mung bean is harvested, it is time to dry or dry it so that the moisture content of the seed is below 14%, and it can cause all kinds of bean images to die at high temperatures. When the dried green bean is stored, the surface is covered with a layer of 15 to 20 centimeters of arbor or fine sand, which can prevent adult oviposition. The family stores mung beans, which can be packed in small sealed pots and bellies, such as Coca-Cola bottles, dry explosion bottles, etc., and can be removed when not in use. In addition, the mung bean may be sensitive to the odor of peanut oil, and the smell of peanut oil does not lay eggs. Apply 0.1% peanut oil on the seed surface and seal it in a plastic bag to reduce insect damage.
