Abstract: | Results showed that, under laboratory conditions, LC50 values for Destruxin A-760 and Destruxin A-724 were 58 and 66 ppm, respectively against M. persicae. Under field conditions, the percentages of infested plants with M. persicae were significantly decreased after treatments with both Destruxin A-760 and Destruxin A-724 as compared with the corresponding controls. In Nobaryia, weights of tomato yield were 3158 and 3988 kg/feddan (F) when Destruxin A-760 and Destruxin A-724 whereas the control yielded 2169 kg/F in the corresponding controls, respectively. While the corresponding yield in EL Sharkia (Zagazig) were 3569 and 3599 kg/F following the same order as compared to 2169 ± 36.82 and 2000 ± 80.54 kg/ F, respectively in the control. The study showed that C. undecimpunctata exhibits relatively high and reasonable resistance to Destruxin A-760 and Destruxin A-724 at their highest lethal concentration (LC) (i.e., 44 ppm) for treated insects. |
