The main effects and interactions for all factors proved to be significant (Concentration: F = 2.386, df = 6, 1002, \(p<0.001\); Exposure Time: F = 4.457, df = 2, 1002, \(p<0.001\); Concentration \(\times\) Exposure Time: F = 2.113, df = 15, 1002, \(p<0.001\)). Different degrees of larval mortality were also observed with _Fusarium longfiundum_ [PERSON], [PERSON], [PERSON], [PERSON] and [PERSON] (Hypocreales: Nectriaceae), ranging between 13 to 67% on the 9 th day of the experiment (Table 6). All applied doses differed significantly from the control, with the lower doses of 10\({}^{3}\), 10\({}^{4}\), 10\({}^{5}\), 10\({}^{6}\) and 10\({}^{7}\) resulting in a mortality rate of 13 to 46% by the 9 th day. The main effects and interactions for all factors proved to be significant (Concentration: F = 1.286, df = 6, 1002, \(p<0.001\); Exposure Time: F = 3.411, df = 2, 1002, \(p<0.001\); Concentration \(\times\) Exposure Time: F = 2.313, df = 15, 1002, \(p<0.001\)). The highest dose of 10\({}^{8}\) proved to be significantly lethal. _Fusarium pseudoanthophilum_ Nirenberg, O'Donnell and Mubat (Hypocreales: Nectriaceae) also resulted in diverse effects on larval mortality (Table 7). Mortality ranged between 20 to 71%. All applied doses differed significantly from the control, and in the lower doses of 10\({}^{3}\), 10\({}^{4}\), 10\({}^{5}\), 10\({}^{6}\) and 10\({}^{7}\) mortalities were calculated from 13 to 67% by the 9 th day. Regarding the highest dose (10\({}^{8}\)), 81% mortality rate was recorded, demonstrating its effectiveness. The main effects and interactions for all factors proved to be significant (Concentration: \begin{table}

Table 4: Mean mortality (\(\pm\)sd) and Median Lethal Time of \(H\). _armigen_ adults exposed to _F. _chlamydosporum_ var. _chlamydosporum_ for 216 h of two season experiments. Means of the same column followed by the same letter are not significantly different (Tukey test, a = 0.05), Median Lethal Time (hours \(\pm\) sd) was estimated by the Kaplan–Meier method (F = 4.115, df = 6, \(p<0.001\)), HAT: Hours After Treatment.
