## 3 Results  
The present study is the first that evaluates different _Fusarium_ isolates against larvae of _H. armigera_ on field experiments (Table 2). \begin{table}
\begin{tabular}{c c c c c c} \hline \hline  
Control mortality (H\({}_{2}\)O + Tergitol NP9 0.05%) was 2.7% at the end of the experiment. By contrast, fungus _F. solani_ resulted in varying degrees of larval mortality, which was proportional to the concentration used (Table 3). Larval mortality ranged on the 9 th day of the experiment between 30 to 91%. All applied doses differed significantly from the control, with the lower doses of 10\({}^{3}\), 10\({}^{4}\) and 10\({}^{5}\) inducing 30 to 67% mortality by 9 th day. In the doses of 10\({}^{6}\), 10\({}^{7}\) and 10\({}^{8}\) the recorded mortalities were significantly higher compared with the control, in all cases. The main effects and interactions for all factors proved to be significant (Concentration: F = 2.107, df = 6, 1002, \(p<0.001\); Exposure Time: F = 4.031, df = 2, 1002, \(p<0.001\); Concentration \(\times\) Exposure Time: F = 1.716, df = 15, 1002, \(p<0.001\)). _Fusarium chlamosporum_ var. _chlamudosporum_ (Hypocreales: Nectriaceae) induced larval mortality that ranged between 23 to 77% on the 9 th day of the experiment (Table 4). A significant difference with the control was observed, with the lower doses of 10\({}^{3}\), 10\({}^{4}\), 10\({}^{5}\) and 10\({}^{6}\) recorded mortality rates ranging from 23 to 60% by the 9 th day. In the case of the higher doses of 10\({}^{7}\) and 10\({}^{8}\), significant mortality was observed ranging from 73 to 77%. The main effects and interactions for all factors proved to be significant (Doses: F = 3.194, df = 6, \begin{table}

Table 3: Mean mortality (\(\pm\)sd) and mean Median Lethal Time of _H. armigen_ larvae exposed to _F. solani_ for 216 h of two season experiment. 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 = 3.220, df = 6, \(p<0.001\)), HAT: Hours After Treatment. 1002, \(p<0.001\); Exposure Time: F = 5.017, df = 2, 1002, \(p<0.001\); Doses \(\times\) Exposure Time: F = 1.506, df = 15, 1002, \(p<0.001\)). _Fusarium tonkinense_ (Bugnic.) [PERSON], [PERSON] and [PERSON], (Hypocreales: Nectriaceae) also, showed different degrees of larval mortality (Table 5). On the 9 th day of the experiment larval mortality ranged between 20 to 71%. 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 23 to 67% by the 9 th day. The highest dose of 10\({}^{8}\) induced 71%, a mortality proved to be significantly lethal.
