Among these‚ organochlorine (OC) insecticides‚ used successfully in controlling a number of diseases‚ such as malaria and typhus‚ were banned or restricted after the 1960s in most of the technologically advanced countries. The introduction of other synthetic insecticides – organophosphate (OP) insecticides in the 1960s‚ carbamates in 1970s and pyrethroids

heterocyclic groups. In medicinal or agricultural terminology‚ the word “organophosphates” refers to the insecticides group‚ and to nerve agents that inhibits Acetylcholinesterase. The OPs exert their toxicological effect by nonreversible phosphorylation of esterases in the CNS (central nervous system).

the cause- the mosquito. A scientist named Dr. Paul Herman Muller made an insecticide-DDT (dichlorodiphenyltrichloroethane) in 1939. Although he was not the first to invent the chemical‚ he was the first to use it as an insecticide‚ when he realized it killed bug and insects (Davis‚ 1971). DDT was used to kill insects causing diseases such as body lice‚ malaria‚ and typhoid fever. The use of the insecticide dropped the cases of malaria in the United States‚ South Africa and other countries

INTRODUCTION A. Rationale The researchers chose this issue because of the increasing incidents of dengue fever cases in the region & in the country. They believe that this study will greatly contribute to the prevention of insect bites especially in younger children. The researchers are aiming that it will help minimize the cases of dengue which is considered as a year round disease & is fatal.

From experimental observations‚ it has been concluded that the amount of propoxur needed to kill 50% of the test subjects (referred to as LD50) was 0.0487(%w/v) which deduces to be 0.22012mg per cockroach (calculated
