The term "salty borer" or "spot borer" is a type of rice borer that belongs to the common stalk pest, and is one of the common rice pests. The history of rice stem borer has caused a large area of ​​rice damage and has caused great damage to rice and other crops. For the prevention and control of borer pests such as Erhuaia, the most important issue is the identification and control of rice borer worms. Through the use of agricultural perspective instruments in the survey of larval populations of S. indica, people can not destroy rice. In the case of crops, effective identification of S. indica larvae provides a scientific basis for carrying out timely and effective prevention and control work.
From the aspect of egg → larvae → larvae → adults (moths) to a generation, the harmful characteristics of rice stem borer are that the newly hatched larvae of rice at the seedling stage and the tillering stage are first clustered in the leaf sheath and cause dead sheath; The larvae, scattered into the stem, endangered the dead heart; rice booting period and heading period, larvae intrusion damage, resulting in dead booting spikes and white spikes; in the milk ripening damage caused by insects, a serious threat to rice production. From the hazard characteristics, we can see that the larvae of S. insults are very serious for rice crops. Therefore, to ensure the safety of rice cultivation, effective measures should be taken to prevent and control them during the incubation period of their larvae. The application creates conditions for scientific prevention and control.
During the larval period, the stem borer has a strong concealment, and it is difficult to accurately judge the morphological characteristics of rice in the early stage of its damage to rice, let alone accurately investigate the density of the larvae of the larvae. However, after the application of the agricultural perspective instrument, people can use the perspective function of the instrument to scan the pictures to understand the distribution of insect pests in vivo, and provide technical conditions for checking the pest situation of borer borers, etc., at any time, and at the same time, once the affected strains are found, The timely treatment can not only reduce the number of insects, but also effectively prevent the damage of the larvae and effectively ensure the growth of rice and other food crops.
