C ourtier-Orgogozo et al [1] argue that public debate and better governance are needed to properly control the use of gene editing for controlling pests in agriculture. They are correct in their assessment that this “could lead to multiple and uncoordinated releases of gene drives into the wild, which is likely to cause unpredictable ecological disturbances with farreaching consequences”. Howev...

Secondary pest outbreaks occur when the use of a pesticide to reduce densities of an unwanted target pest species triggers subsequent outbreaks of other pest species. Although secondary pest outbreaks are thought to be familiar in agriculture, their rigorous documentation is made difficult by the challenges of performing randomized experiments at suitable scales. Here, we quantify the frequency...

As growers switch to transgenic crops and selective insecticides that are less toxic to natural enemies, natural enemies can become more important in agricultural pest management. Current decision-making guides are generally based on pest abundance and do not address pest and natural enemy toxicity differences among insecticides or the impact of natural enemies on pest survival. A refined appro...

The hemlock woolly adelgid, Adelges tsugae Annand, is an invasive species reducing the populations of eastern hemlock, Tsuga canadensis L. Carrière, throughout the eastern United States. Systemic imidacloprid and horticultural oil are the primary chemicals used to control infestations of this invasive pest; however, the impact of these two chemicals on nontarget canopy insects is unknown. This ...

A comprehensive survey of the occurrence and fate of pesticides and organic contaminants in soils from an intensive agricultural area devoted to horticultural production in plastic-based greenhouses has been performed to determine if the operation under integrated pest management practices has contributed to reduce the levels of these compounds. Almería province (south-eastern Spain) was select...

The widespread use of pesticides leads to the contamination groundwater, which harms environment and threatens life. goal current study was determine degree pesticide groundwater in agricultural regions with varying degrees use. In 15 districts Punjab province Pakistan, chemical residues major groups including, neonicotinoids, organophosphates, carbamates pyrethroids were detected water samples...

Ethephon (ETF), one of the plant growth regulators, is used in agricultural systems as a valuable tool due to its property of regulating fruit maturation. Here, we aimed to investigate the toxic effects of ETF on the hemolymph metabolites of the greater wax moth, G. mellonella which is an experimental animal and a serious pest in wax. Different doses of ETF (250–390 μg/5 μl) were injected with ...

Gene suppression via RNA interference (RNAi) provides an alternative strategy for insect pest management. The ingestion by insects of double-stranded RNAs targeting essential insect genes can trigger RNAi and lead to growth inhibition, developmental aberrations, reduced fecundity, and mortality. This RNAi response is particularly acute in certain coleopteran species, most notably the western co...

Over the past 50 years, crop protection has relied heavily on synthetic chemical pesticides, but their availability is now declining as a result of new legislation and the evolution of resistance in pest populations. Therefore, alternative pest management tactics are needed. Biopesticides are pest management agents based on living micro-organisms or natural products. They have proven potential ...
