The General Approaches To Insect Control
When developing an overall pest management strategy it is helpful to consider all of the available options. Most specific insect control methods can be classified into the following major categories: cultural control, host resistance, physical control, mechanical control, biological control, and chemical control.

TOXIC WASTE FROM PESTICIDES IS TICKING TIME BOMB FOR POOR COUNTRIES
High quantities of toxic chemical waste from unused or obsolete pesticides are posing a continuing and worsening threat to people and the environment in Eastern Europe, Africa, Asia, the Middle East and Latin America, FAO warned on 9 September.
Obsolete pesticides are left over from pest control campaigns. Stockpiles have accumulated because a number of products have been banned for health or environmental reasons, but were never removed and disposed of. Stocks remain where they are stored and often deteriorate to contaminate the environment and put people at risk.

Using Pheromones for Insect Management
The insect's world is filled with many odors. Insects use these odors to cue them in a variety of complex social behaviors, including courtship, mating and egg laying. Scientists and pest control specialists have known about these complex communication systems for decades. Recently, this high technology has been made available for use by the average person because these chemicals, called pheromones (pronounced fer-a-mons), can be produced synthetically...
