Abstract: | The adult feeding behavior of Liriomyza huidobrensis and L. trifolii was studied in beans of the variety “Catarino.” The insects
were placed on a bean leaf and its behavior observed and recorded on DVD for a period of 30 min. An ethogram was constructed
based on the different behavior parameters that were identified. The time that each species used in each behavior parameter
was registered and compared between the two species. When placed in the arena the two species behaved in a similar manner,
although some differences were observed. The adaptation of the leafminers species to the “Catarino” bean variety under these
experimental conditions and the possibility to use some behavioral parameters as indicators of the preference of these insects
in relation to the host plant are discussed. |
