High temperature stress can hinder the development of cowpea resulting in several damages including vegetative and reproductive phases of the crop. In this context, the objective of this study was to select cowpea cultivars tolerant to high temperature stress using various parameters related to physiological, biochemical, and yield aspects. For this, the cultivars Carijo´, Itaim, Pujante, Rouxinol, and Tapahium were used, maintained in two temperature regimes: 20?26?33 C and 24.8?30.8?37.8 C. The experiment was carried out in growth chambers, in a 5 9 2 factorial arrangement (cultivars 9 temperature regimes). Responses differentiated among the cultivars Carijo´, Itaim, Pujante, Rouxinol, and Tapahium with the increase of 4.8 C in air temperature. The high temperature promoted a greater quantity of aborted flowers, leading to a reduction in the yield of the cultivars Carijo´, Pujante, Rouxinol, and Tapahium. The photosynthesis, stomatal conductance, leaf transpiration and enzymatic activities were significantly influenced by high temperature. From the combination of the responses of biometric, physiological and productive variables, the cultivar Itaim can be considered as tolerant to an increase of 4.8 C in air temperature. |

Abstract Blastospores are yeast-like infective cells to arthropod pests and can be obtained shortly by liquid culture. However, fungal isolates exhibit striking variation in production, desiccation tolerance and virulence. In this study, we screened three isolates of Beauveria bassiana (Balsamo) Vuillemin and three of Cordyceps fumosorosea (Wize) (Hypocreales: Cordycipitaceae) for blastospore production and assessed desiccation tolerance by air drying. The virulence of these isolates were determined against Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) biotype B, Spodoptera frugiperda (J.E. Smith) and Chrysodeixis includens (Walker) (Lepidoptera: Noctuidae). The isolates ESALQ-1296 and ESALQ-3422 of C. fumosorosea and ESALQ-4958 of B. bassiana yielded blastospore concentrations above 1 × 109 ml−1, but only the two C. fumosorosea isolates retained viability rates above 75% after drying. Blastospores of both fungal species were more effective in killing the three insect species than aerial conidia. In summary, blastospores of C. fumosorosea ESALQ-1296 hold the best promise for broad-spectrum pest control in soybean. |
