Response of some mungbean [Vigna radiata (L.), wilczek] varieties to the broad bean leaf miner, Liriomyza trifolii (Burgess) infestation and effect of infestation on seed yield in North Delta region [electronic resource].

Includes references.

Two field experiments were carried out at the experimental Farm and Economic Entomology Department, FaCUlty of Agriculture, Kafr EISheikh, Tanta University during the growing seasons of 2004 and 2005. The first one to investigate the ecological aspects of the broad bean leaf miner, Liriomyza trifolii (Burgess) in mungbean fields and the second one to determine the agronomic parameters and evaluating the relative susceptibility of six mungbean varieties to L. trifolii infestation. The results showed that the infestation rate increased with increasing in plant age. The obtained results showed that L. trifolii had the highest rate of infestation in August and it had two peaks in the first season and three peaks during the second one. Data of field evaluation of six mungbean varieties for L. trifolii infestation showed that Kawmy-1 and KPS₂ were less susceptible varieties. Data showed that Kawmy-1 and KPS₂, surpassed UTT,M₅₃, KPS₁ and Giza-1 in chlorophyll content, both weight and number of pods/plant and seed yield/fed. It could be concluded from this study that sowing of Kawmy-1 and KPS₂ mungbean varieties could be recommended to get high seed yield of mungbean and would be a best source for resistance of L. trifolii to be used in crossing programs for improving the commercial cultivars at Kafr EISheikh region. Such entomological studies are needed before initiating a proper integrated pest management (IPM) program in the future.
