Ecologically Sustainable Chemical Recommendations for Agricultural Pest Control?

Journal of Economic Entomology, 2007
Effective pest control remains an essential part of food production, and it is provided both by chemicals and by natural enemies within agricultural ecosystems. These methods of control are often in conflict because of the negative impact of chemicals on natural enemies.

Biological Control as a Supplement to Chemical Control of Insect Pests

Nature, 1944
WHILE chemical control is in general the most effective method of pest control known and therefore the most generally used, an increasing amount of experimental proof has accumulated during recent years showing that this method has a very serious limitation. Repeated applications of chemical control result in an unintended artificial selection of those

Rational chemical pest control

1999
Au cours des trente dernières années les chercheurs ont travaillé pour proposer une utilisation raisonnée des insecticides de synthèse. Cela suppose une connaissance approfondie des ravageurs que l'on veut combattre : cycle biologique, dynamique des populations, facteurs naturels de régulation des populations.

Use of Pest Control Chemicals in Texas

American Industrial Hygiene Association Journal, 1973
The author reviews the impact on the economy of the State firom the use of certain chemical elements and compounds for the abatement and control of vectors that compete with man for his needs of food and fiber. The size, topography and climate of Texas offer many favorable ecological niches for the maintenance and transmission of arthropod-borne ...

Chemical Control of Some Squash Pests in U.A.R.

Zeitschrift für Angewandte Entomologie, 1972
AbstractFour experiments were carried out, to evaluate the effect of granules and emulsions on squash pests and to detect their effect on the percentages of germination and yield insecticides.In the first experiment, the seeds were treated, at planting time.

Chemical Controls for an Integrated Pest Management Program

North American Journal of Fisheries Management, 2019
Abstract Chemical controls ranging from natural products to synthesized chemicals are widely used in aquatic pest management activities. Chemicals can be used to lure organisms to traps or can cause direct mortality by altering the physiological function of an organism. Much of what is known about controlling pests with chemicals is from

New approaches to the chemical control of arthropod pests of livestock

International Journal for Parasitology, 1987
Abstract Chemicals are important tools in our effort to control livestock ectoparasites, and they are likely to remain so in the foreseeable future. Chemical control is the most widely used and in most cases the only method available to the producer.

Recent Developments in the Chemical Method of Pest Control

Madras Agricultural Journal, 1954
It is a well-known fact that on an average about ten percent of the produce is lost by the cultivators every year due to depredations of crop pests. Intensive research has beon in progress in the Madras State for the past four decades on insecticidal methods of pest control. Based on the results obtained so far, an attempt is made in this paper to give
