Abstract
Laboratory studies were conducted to evaluate the toxicity, joint action and cytological effects of the biological agents B.T. Delfin & Dipel and Sabadilla against the spiny and pink bollworms. The results indicated that Delfin and Dipel were more effective against the spiny bollworm than the pink bollworm. The LC50​ values were higher on the 1st instar larvae of both insects by the film residue method when compared with those calculated from the dipping method against the 4th instar ones. Dipel and Sabadilla was more effective on the spiny bollworm than the pink bollworm. It was also more effective on the 1st instar larvae by film residue method than on the 4th instar ones by dipping method. It was noticed that the addition of Sabadilla to both pathogen agents enhanced the efficiency after 72 hrs of treatment and showed a remarkable potentiation effect in controlling these pests. Moreover, the pathogen agents or/and Sabadilla induced several types of chromosomal aberrations. while Delfin produced the highest percentage of abnormal male gonad cells. Sabadilla was the lowest in producing the abnormalities.
