Pesticides have a role in public health as part of sustainable integrated mosquito management. Other components of such management include surveillance, source reduction or prevention, biological control, repellents, traps, and pesticide-resistance management. We assess the future use of mosquito control pesticides in view of niche markets, incentives for new product development, Environmental ...

Mangel, M. and Plant, R.E., 1983. Multiseasonal management of an agricultural pest. I: Development of the theory. Ecol. Modelling, 20: 1-19. A framework for analyzing the trade-off between economic yield from a crop and buildup of resistance to pesticide caused by repeated applications of pesticide is developed. The analysis begins with the case of age-independent pest dynamics, in which pests ...

To study adaptation, it is essential to identify multiple adaptive mutations and to characterize their molecular, phenotypic, selective, and ecological consequences. Here we describe a genomic screen for adaptive insertions of transposable elements in Drosophila. Using a pilot application of this screen, we have identified an adaptive transposable element insertion, which truncates a gene and a...

The Guthion-resistant strain of walnut aphid parasite, Trio x y s p a II i d us. was mass reared in the greenhouse on potted walnut trees and released into five commercial walnut blocks near Colusa, Stockton, Modesto, and Hanford. Parasites successfully established in four of the five sites, surviving on field rates of Guthion and Supracide. The Guthion-resistant strain persisted in the release...

This study analyzed consumer response to potatoes tested for pesticide residues. These potatoes were packed in five pound bags and priced at three different levels in participating supermarkets. Even when sold at identical prices, consumers continued to favor the traditional round white over the residue-tested potatoes. However, sales of residue-tested were equal at all three price levels, indi...

Insecticide resistance has been known to be prevalent in several insect species including mosquito. It has become a major problem in vector control programme due to pesticide resistance through detoxification enzymes. The present study investigated the toxicity of Ae. aegypti to organophosphates and pyrethroid insecticide and biochemical mechanisms involved in insecticide resistance in larval p...

BACKGROUND Pesticide consumption is increasing in Bolivia as well as pest resistance, pesticide poisonings and pollution of the environment. This survey evaluates the training of small holder farmers on pesticide handling and ecological alternatives to reduce the negative pesticide effects. METHOD A baseline survey was performed in 2002 and follow-up surveys in 2004 and 2009. Farmers were sel...

The sustainable intensification of agriculture requires solutions for a large-scale reduction pesticide use while sustaining agricultural yields. Pesticide-free production standards, which bring together the strengths all food value chain actors, could be cornerstone this transformation. In Switzerland, non-organic, private–public standard pesticide-free wheat is currently being introduced by p...
