The growth factors of plants and insects

Biofunctional molecules are those compounds that control characteristics of organisms such as growth, metamorphosis, homeostasis, aggregation and reproduction. Insect secretions contain endocrine hormones (for example brain hormone & juvenile hormone) and exocrine secretion (for example pheromones & defensive secretion). Thus, juvenile and anti-juvenile hormones could be used as insect growth regulations. Pyrethrins are the active substance of pyrethrums (kind of flower). Insects can also be control by pyrethrins, the same synthetic compounds, and anti-Feedants. Naturally occurred plant hormones are auxin, gibberellins, cytokinin, brassinosteroids, ethylene, abscisic acids that regulate plant growth. In addition, plants are known to produce antimicrobial compounds named phytoalexins as defense substances when attacked by pathogenic micro-organisms. In this article, we investigate the introduction, preparation, and performance of insect and plant growth regulations in the life of insects and plants in the environment.
