Abstract:

Agriculture is adversely affected by numerous pests and insects, leading to reduced yield and poor quality of the products. Use of synthetic pesticides was the most common method for pest control in many agricultural crops. These synthetic chemical has harmful effects on crops, animals and also human beings. In this research, green regulation technology was applied in order to control the harmful effects of pesticides. Also, laboratory experiment was conducted at the International Institute of Tropical Agriculture Benin, to study the virulence of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) strains (Bb6, Bb11, Bb115, Bb116 and Bb362) on cabbage Plutella xylostella (L.) (Lepidoptera: Plutellidae). The doses 0 (control) 104 105 106 107 108 and 109 conidies.ml-1 of 5 different strains of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) were applied topically on the third stage larvae of P. xylostella. After the application of doses, the survival rate of larvae was examined after the direct effect of doses on strains in cages at greenhouse conditions. Different types of parameters of larvae were measured in terms of mortality and sporulation rates, the number of pupae formed the number of adults that emerged and number of eggs laid by survived adults. Collected data was used for statistical analysis, using Cox-regression. The results, we concluded that Bb11 strain of Beauveria bassiana (Balsamo) produced virulence compared to other strains at 109conidia/ml. On the other hand, Bb6 strains lower virulence at 109conidia/ml as compared to control dose. Due to the larvicidal effect of different fungus strains, the percentage of female adult decreased significantly less of with their weight development control.
