Identification of Natural Enemies of Tuta absoluta in jordan

  Biweekly field visits starting from January to the end of April 2011 were conducted to tomato fields

(open and plastic houses) heavily infested with the tomato borer Tuta absoluta, in order to survey natural

enemies associated with this pest. Three hemipterans were found: Orius albidipennis, Orius sp. (Anthocoridae)

and Nesidiocoris tenuis (Miridae). In addition, the parasitic wasp Bracon (Habrobracon) concolorans,

(Hymenoptera: Brachonidae) is recorded for the first time from Jordan.

Biweekly field trips were conducted to collect natural enemies associated with T. absoluta in heavily

infested tomato fields in the different parts of Jordan from January to the end of April 2011.The survey

included farms in Central and Southern Jordan Valley (Ghour As Safi, at southern tip of the Dead Sea). The

specimens were collected by aspirator or by direct picking from tomato in open fields and plastic houses. Most of

the natural enemies, especially the parasites, were collected after the infestation exceeded the economic

injury level and no more insecticides were applied. The specimens were kept in small vials containing 75% alcohol

and sent to the National History Museum in UK to confirm our preliminary identifications. Voucher

specimens were preserved in the University of Jordan Insect Museum.
