المستخلص: This study discussed the effect of the factors (temperature, humidity, humidity content) of the seeds in the life of Callosobruchus maculates F. and its developing, this study used the degrees of temperature (25, 30, 35, and 40)° and the percentages of humidity (50, 70)%, the humidity content was (17.5, 18.5)%, and each factor has been studied alone with its affect on the life of the insect, then it has studied the companion of these factors with each other including the changes which appeared over the number of the eggs and the period of the hatching, the period of its maggot and cocoon and the number of the produced insects and the percentage of the producing progeny and the period of life of the complete insect, all these changes should be regarded in order to reach to the best affect which happens after gathering the three factors with each other (temperature, humidity, humidity content) in order to be used in striving the insect and because it is one of the most harmful insects in the stores of seeds. The study showed the best results which affected the life of this insect that resulted from the gathering of the three factors (temperature, humidity, humidity content) of the seeds when the temperature is 40° and humidity 50% and humidity content (17.5, 18.5)%, and the lower number of the eggs was (36.6), and the period of hatching longed to about (19.8) days, the period of maggot was (21) days, the period of cocoon was (9.3) days, the lower number of the producing insects was (29) days, the period of the progressing was (50.1) days, the shorter period of age of the complete insect was (3) days, under the same circumstances the lesser percentage of the producing progeny was (48.9)% in the degree of temperature 25°, and 10% humidity and 18.5% humidity content.

Also, this study showed the effect of the vegetable oils on the insect’s life and its developing, these oil) myrtle, mint, carnation, aniseed) are used as an aqueous and alcoholic extracts in the condensations (1, 3, 5)%, so the study proved that the best results which affect the life of the insect that caused the lower number of eggs was (15.1) when the insect treated with the aqueous extract of the mint oil with condensation (5%), the period of hatching was long to about (12.8) days when the insect treated with alcoholic oil of myrtle in condensation (1%), the longest period of maggot was (22.8) when the insect treated with the alcoholic extract of the mint oil in condensation (5%), the longest period of cocoon reached to (14.2) days when the insect treated with the alcoholic extract of the mint oil in condensation (1%), the lower number of the produced insects was (9.4) which affected with the aqueous extract of the mint oil in condensation (1%) and the longest period to the developing was (49.2) days when the insect treated with alcoholic extract of the mint oil in condensation (5%).
