Résumé : This study was carried out at the Experimental Farm of the Faculty of Agricultural Sciences, University of Gezira, during the seasons 1996/97 and 1997/98, on two faba bean varieties: Shambat and SML. Two experiments were conducted: one for each variety where two treatments were laid out in a randomized complete block design with six replicates. One treatment was the natural infestation of leaf miners (untreated plots), and the other was protected by the insect growth regulator Trigard 75% wettable powder (treated). In both seasons, the untreated plots were heavily infested by the leaf miners, while the protected plots were lightly infested. Infestation resulted in yield losses of 22.86% and 42.25% for Shambat and 29.16% and 27.64% for SML during the two seasons, respectively. Also, there were highly significant differences (P<0.01) in plant height and number of pods between the treated and the untreated plots. Negative correlations between the percentage of leaf infestation and plant height in the treated plots were detected. (Texte intégral)
