| Abstract | ||
| The effect of low temperatures on the different stages of The southern cowpea weevil Callosobruchus maculatus (F) Bruchidae, Coleoptera was carried out. The results indicated that mortality ratio increased by increasing exposure period. The number of unhitching eggs was 10,the number of the dead larvae was 9.66,abd dead pupa was 6.66, in the degree temperature -18 ºC and with a time exposure of 60 minutes. Some studies were carried out on controlling this pest by means of non chemical pesticides agents, In these studies , four concentrations (at 0.2, 0.4, 0.6 and 0.8) of four different types of botanical oils (bitter almond, cumin, ginger and cinnamon) were tested. The results showed that the repellent and mortality ratio were highest (80% and 100%)with the concentration of 0.6 and 0.8 for all types of oils used. | ||
