The present book is a collection of selected original research articles and reviews providing adequate and up-to-date information related to pesticides control, assessment, and toxicity. The first section covers a large spectrum of issues associated with the ecological, molecular, and biotechnological approaches to the understanding of the biological control, the mechanism of the biocontrol agents action, and the related effects.
A preliminary study was carried out in mid 1999 on the status and potential impact of the introduction
of exotic fish species in the Mekong Basin. Introductions have been made for four main purposes:
aquaculture, stocking into lakes and reservoirs, pest control (mosquito) and the aquarium fish trade.
Introductions of exotic species and movements of large quantities of fish for stocking are accompanied
by risks to the environment, the possibility of native fish species declining through competition, predation
or genetic interference, and the possible spread of disease....
Bacillus Thuringiensis (Bt): A pest control product that is made from beneficial bacteria and applied as a spray to
kill caterpillars. Sold under a variety of names such as Thuricide, Dipel, and Bio-Worm and others. Use Bacillus
thuringiensis ëIsraelensisí (Bti) in water for the control of mosquito larvae and for control of fungus gnats in pot
plants in office buildings. Use Garrett Juice with Bt for extra effect. Molasses also helps. It provides protein and
keeps insect-killing bacteria alive on the foliage longer ñ even during rain.
In anautogenous mosquitoes, egg development requires blood feeding and
as a consequence mosquitoes act as vectors of numerous devastating dis-eases of humans and domestic animals. Understanding the molecular
mechanisms regulating mosquito egg development may contribute signi-ficantly to the development of novel vector-control strategies.
