Introduction
It is well known fact that the production and use of essential oils did not become common until second half of the sixteenth century.In 19th century gradually the use of essential oils in medicinal drugs become quite popular as perfumes,beverages,food stuffs etc.
The led to the investigations of essential oils and elucidation of their compounds for the use in solving various day to day problems of life. One such problem has been to control insects which are considered as serious foe towards mankinds.
Thus it has struck as a sound rational to use essential oils in controlling insects. The essential oils as such have been investigated against several insects. Among the physiologically active substance in insect known today the attractants are the chemical substances which excite or lure the opposite sex for purpose of mating. In 1959 these chemicals were1,2 named as pheromones these attractants possesses potential utility in controlling insects by being employed to lure large numbers of one sex to their death in bated traps. The plants also produce such attractants and a comprehensive review on the subject is available in literature3.The same is true for essential oil also. An investigation of vogel4 has revealed the mixture of twelve terpenoids in the flowers of catasetum cycnoches and stanhopea. Which were attractive to male Euglossa bees indicative of being sex attractants due to highly excited behaviour of these insects.

Material and Methods
The essential oils four plants Abutilon indicum Bothriochloa pertusa Muraya exotica Micromeria capitellate Vitex nugundo. The oil was extracted with chloroform from aqueous portion and purified by distillation under reduced pressure. The oil so obtained was tested for its insects controlling activity and results are shown in given table as follows.
Results and Discussion
From above observation it seems clear that essential oil as whole is quite effective in checking eggs of above insects. All essential oils are quite effective against above insect except Muraya exotica which is less effective in initial as well as latter stage. Possibilities of above compounds to check the insects growth is quite suitable.
