In the Arab Republic of Egypt, work was done to study some aphid species, Nezara viridula whitefly, and Sesamia cretica infestation-associated parasitoids with aphid species. Diaeretiella rapae emerged as a major parasitoid of aphid species. All parasitoids that emerged from collected egg masses of Nezara viridula were identified as Trissolcus mega...

Fungi are used to synthesize metal nanoparticles such as silver nanoparticles (AgNPs) because of their specifications as lower toxicity and eco-friendly behavior. Extracellular mycosynthesis of Lecanicillium lecanii silver nanoparticles (AgNPs) was performed, which was done by a redox reaction, where the filtrate crude of L. lecanii acts as a reduc...

Pesticides are widely used for crop protection, increasing agricultural product yield, and public health programs. Traditional pesticides include insecticides, herbicides, rodenticides, miticides, fungicides, nematicides, fumigants, and antimicrobial agents. However, these pesticides can negatively affect public health, the ecosystem, and biodivers...
