Sericulture is an agro-based sector and also one of the major areas of agricultural entomology. There are four different kinds of silk produced by this sector: mulberry, muga, eri, and tassar. The demand for this mulberry silk is high in the global agricultural market. In order for mulberry silkworms (Bombyx mori) to be raised successfully, host plants are essential throughout their cultivation. However, several insect pests severely infest the host plant. The main insect pest for the mulberry tree among these is defoliators. They have an impact on different components of the plant, including the leaf, bud, stem, and other parts. Plants that are infested have reduced leaf output and stunted development. Furthermore, impacted leaves are not conducive to the growth of the silkworm's body. Mulberry is a little, quickly growing evergreen or deciduous tree that is used as a drumstick tree. We have known about its medicinal and dietary properties for a very long time. This tree is vulnerable to a variety of illnesses and insect pests. Neem seed kernel extract and neem leaf water extract are used to treat the prevalent Euproctis fraternal pest. Azadirachta indica (Neem) leaves and seeds were harvested from the field, shade dried, and then ground into powder. The 5.0% stock solution was made using this powder. The following concentrations were then made from the stock solution: 4. 00%, 3. 0%, 2. 00%, 1. 00%, 0. 5%, and 0. 25%. Following treatment against Euproctis fraternal, the current experiment examined and discussed the caterpillar's behavior related to food, body weight loss, and gain.
