آليات مقاومة بعض أصناف الحمص لحشرة حافرة أنفاق الأوراق (Liriomyza cicerina Rondani)‎

Abstract EN

Chickpea leaf miner, Liriomyza cicerina Rondani, is an important insect pest of chickpea, Cicer arietinum L., in Syria.

This study aimed to determine the categories of resistance (antibiosis, antixenosis) of four chickpea lines (ILC 5901, ILC 3800, ILC 3397 and ILC 1929) to the Leaf miner.

The experiments were conducted at the International Center for Agricultural Research in the Dry Areas (ICARDA).

Results showed that the total number of eggs laid by the leaf miner female was significantly higher on the susceptible cultivar (13.3 for ILC 3397) than on the two resistant lines (2.3 and 1.6 for ILC 3800 and ILC 5901) and local cultivar (5.9 for ILC 1929), respectively.

Results of antibiosis test showed that the larval mortality rate on the resistant lines was significantly higher than that on the local and susceptible cultivars, with mortality rates of 82.3%, 72.6%, 26.6% and 20.7% for ILC 5901, ILC 3800, ILC 1929 and ILC 3397, respectively.

The emergence rate of adults from resistant lines was significantly lower than that from local and susceptible cultivars, which reached 1.4%, 11.7%, 23.7 and 68.7% for ILC 5901, ILC 3800, ILC 1929 and ILC 3397, respectively.

There was a positive and highly significant correlation between the leaflet size and the mean number of eggs laid; while the number of hairs was negatively and significantly correlated with the mean number of eggs laid.

Results of this study are useful for the breeding programs to develop chickpea varieties resistant to leaf miner.
