Until now, control strategies for insect pest species have relied on applications of synthetic insecticides. In addition, the effectiveness of these treatments could be reduced due to the resistance of insect populations to insecticides. The irrational use of chemical control strategies also has negative consequences for non-target organisms and threatens human health. A promising alternative to traditional insecticide formulations is the development of nanomaterials for insect control. Especially, silicon (Si) has been shown to be used to control a range of insect pests across taxa in various crops. It has been known to induce the tolerance of anti-xenotic and antibiotic species to insect parasites in various crops. In recent years, silica (SiNPs) has been used as a source of silica for both soil and foliar application to control insect pests. SiNPs are also used as a vehicle for the targeted application of insecticides due to their controlled release efficiency. In this work, we summarized the state of knowledge on synthesized silica nanoparticles (SiNPs) from Padina Tetrastomatica Seaweed as used in pest control. In addition, the aspects of their synthesis, the mechanism of action, the use in insect pest control, the potential for use as an insecticide vector, and the environment are described in detail.
