Published in 2019 at "Archives of insect biochemistry and physiology"

DOI: 10.1002/arch.21615

Abstract: Synthetic compounds that mimic the action of juvenile hormones (JHs) are founding members of a class of insecticides called insect growth regulators (IGRs). Like JHs, these juvenoids block metamorphosis of insect larvae to reproductive adults.… read more here.

Published in 2024 at "Journal of agricultural and food chemistry"

DOI: 10.1021/acs.jafc.4c00312

Abstract: Insect growth regulators (IGRs) are important green insecticides that disrupt normal growth and development in insects to reduce the harm caused by pests to crops. The ecdysone receptor (EcR) and three chitinases OfChtI, OfChtII, and… read more here.

Published in 2022 at "ACS Omega"

DOI: 10.1021/acsomega.2c05977

Abstract: As a result of some major problems that come from using insecticides, the use of safe alternatives to these pesticides has become very necessary. Thus, a novel series of predicted toxicologically active urea, thiourea, thiosemicarbazide,… read more here.

Published in 2019 at "Journal of Economic Entomology"

DOI: 10.1093/jee/toz164

Abstract: Abstract Immature stages of the boll weevil, Anthonomus grandis grandis Boh. (Coleoptera: Curculionidae), develop protected inside cotton fruiting structures. Therefore, the adult beetles have become the main target of insecticide applications. The use of insect… read more here.

Published in 2021 at "Agronomy"

DOI: 10.3390/agronomy11102002

Abstract: The potential of insecticides that affect the growth and insect development to control Euprosterna elaeasa was evaluated. Fenoxycarb, methoxyfenozide, pyriproxyfen, and tebufenozide were assessed against E. elaeasa larvae for toxicity, survivorship, and feeding inhibition in… read more here.

Published in 2023 at "Biomolecules"

DOI: 10.3390/biom13030461

Abstract: Glutathione S-transferases (GSTs) are conserved in a wide range of organisms, including insects. In 2014, an epsilon GST, known as Noppera-bo (Nobo), was shown to regulate the biosynthesis of ecdysteroid, the principal steroid hormone in… read more here.
