Recently, farmers in Liaocheng reported that eggplant has a hard-shelled insect that specifically bites eggplants and also eats leaves of eggplant, causing unintentional eggplants, falling flowers, missing leaves or holes in the leaves, and severely affecting the normal growth of eggplant.
In the vegetable shed of this vegetable farmer, we saw the hard-shelled worm that is harming eggplant, and we also saw the leaves of aubergine that have been nicked by the worm. According to local farmers, he planted eggplant for 6 years. He had never seen such an insect. In the past few days, he had used pesticides such as avermectin and methotrexate, which did not work.
The hardy insect called by the vegetable grower is called cotton tip elephant, which is also known as cotton weevils and cotton gray elephants. They are mostly distributed in the Yellow River, the Yangtze River, the Northwest inland, and the northeastern provinces and districts. The previous years were mainly in cotton growing areas. Heavy damage to cotton, in addition to beans, corn, sweet potatoes, millet, hemp, peach, sorghum, wheat, rice, peanuts, grasses and poplars. In recent years, due to the development of facility agriculture, the cotton tip elephants have also entered the shed area and endangered vegetables such as eggplant.
One year old, the cotton tip is mostly larvae wintering in the soil of cotton, eggplant, soybean, and corn roots. Larvae are 25-40 cm deep from the topsoil. In April and May of the open season, the temperature rose, and the larvae rose to the topsoil. In early June, adults emerged, and from mid-June to mid-July, they entered the period of destruction. Due to the influence of temperature in the greenhouse, greenhouse tippets may cause damage to the vegetables in the facilities in advance in February and March, especially for eggplant seedlings, which often causes eggplants to be unintentional.
Prevention methods: For large numbers of fields, adults will dig 10cm deep pits in the field during the exhumation period. The pits will be covered with poisonous soil, covered with green grass, and then concentrated again in the morning. Another good method is to use the cotton tentacle animation method to take manual capture and concentrate. Chemical control: 50% phoxim milk can be sprayed 1500 times, and also, 50.7% of Le Siben EC can be mixed according to the ratio of 1:150, 30kg of poisonous soil per 667m2, which can not only play a good control effect .
