The study was conducted to determine the cutworms species was infested crop ( corn , cabbage , potato ) in Mosul regon . The study
showed that the crop has an effect on cutworm species domination in the field. The study showed that potato plants cabbage & corn in both spring and fall season infect with the following species of cutworm, spodoptera exigua, Agrotis segetum, Agrotis ipsilon while Spodoptera litura infects potato and cabbage, as for sesamia cretica, Mythimna loreye both of them occurred only in corn field .
The higher weekly captivity was recorded in spring potato, cabbage & corn fields their amount was 7.26,5.91,14.09 adult per week and 32.44, 30.6, 33.7 weekly captivity percentage respectively. While S. litura was the most frequent in traps in fall potato fields with a good weekly average 7.25 adult per week and 35.8 captivity percentage
Their was positive correlation between capture density and temperature in spring and fall potato fields and negative correlation with humidity average and their was no significant positive correlation between capture density and temperature in cabbage & corn fields and non significant negative correlation with relative humidity average

The results of this study revealed that the synergistic ratio of insecticides were varied according to the kind of oil, solvent, and insect stage used in this study. The mixture of Azadirachtin with sesame oil (1:1) ratio and diluted in acetone showed a higher synergistic ratio and relative efficiency on egg stage which reached 1.38 and 27% respectively in comparison with the oil of black cumin seeds (Nigella sativa L.) which reached 0.86 and 15.38% respectively. The higher synergistic ratio and relative efficiency were obtained from treating larval stage by Cyromazine and mixed with sesame oil (1:1) ratio and diluted in acetone in comparison with values of synergistic ratio and relative efficiency of Azadirachtin and Azamethiphose mixed with sesame oil (1:1) ratio on people and adult stage respectively. The results of the degree of synergism confirmed the result of the synergistic ratio.

A simple spectrophotometric method for the determination of p- aminobenzoic acid (PABA) in aqueous solution. The method is based on the reaction of PABA, with excess nitrite, in an acidic medium, to produce the corresponding diazonium salt. After the removal of residual nitrite with sulfamic acid, the diazonium salt is coupled with methyl acetoacetate reagent in basic medium to produce, an intense yellow coloured water-soluble and stable azo-dye which exhibits maximum absorption at 365nm. Beer’s law is obeyed over the range 10-260g of PABA in final volume of 25 ml i.e., 0.4-10.4 ppm with a molar absorptivity of 2.41104 l.mol-1.cm-1 and Sandell sensitivity index of 0.0056g.cm-2, a relative error of –0.70 to +0.43% and relative standard deviation of 0.13 to 1.01% depending on the concentration level. The method has been applied to the determination of PABA result from degradation of procaine-penicillin injection and from tablets of folic acid.
