Journal of Agricultural and Food Chemistry, 2016
The discovery of novel leads and new mechanisms of action is of vital significance to the development of pesticides. To explore lead compounds for botanical insecticides, 77 β-dihydroagarofuran derivatives were designed and synthesized. Their structures were mainly confirmed by (1)H NMR, (13)C NMR, DEPT-135°, IR, MS, and HRMS.

Botanical insecticides effectively control chickpea weevil, Callosobruchus maculatus
Environmental Sustainability, 2018Health hazards associated with the excess use of chemical insecticides used for the post-harvest preservation of food grains has prompted the emphasis on the use of natural insecticides in agriculture. In this regards, botanical insecticides have emerged as one of the best, safer, green, eco-friendly, promising and sustainable alternatives for ...

Nicotine oleate dispersions as botanical insecticides
2004Two alternative extraction media for botanical insecticide nicotine were evaluated in order to increase its recovery efficiency from tobacco leaves: oleic acid oil-in-water (O/W) emulsions and oleic acid. The use of oleic acid O/W emulsions stabilized by calcium caseinate as extraction media in a percolation process showed a recovery efficiency between

Botanical Insecticides in the Twenty-First Century—Fulfilling Their Promise?
Annual Review of Entomology, 2020Academic interest in plant natural products with insecticidal properties has continued to grow in the past 20 years, while commercialization of new botanical insecticides and market expansion of existing botanicals has lagged considerably behind. Insecticides based on pyrethrum and neem (azadirachtin) continue to be standard bearers in this class of ...

Effects of Botanical Insecticides on Hymenopteran Parasitoids: a Meta-analysis Approach
Neotropical Entomology, 2018Botanical insecticides (BIs) are considered a valuable alternative for plant protection in sustainable agriculture. The use of both BIs and parasitoids are presumed to be mutually compatible pest management practices. However, there is controversy on this subject, as various studies have reported lethal and sublethal effects of BIs on hymenopteran ...

Neem and other Botanical insecticides: Barriers to commercialization
Phytoparasitica, 1997In spite of the wide recognition that many plants possess insecticidal properties, only a handful of pest control products directly obtained from plants, i.e., botanical insecticides, are in use in developed countries. The demonstrated efficacy of the botanical neem (based on seed kernel extracts of Azadirachta indica), and its recent approval for use ...
