Natural parasitism of Chrysodeixis chalcites and Autographa gamma (Lep., Noctuidae) eggs on tomato fields. "Boletim do Museu Municipal do Funchal", Supl. Nº. 5: 177-181.0870-3876http://hdl.handle.net/10400.3/794A survey for Chrysodeixis chalcites Esper and Autographa gamma L.(Lep.: Noctuidae) eggs was carried oul on tomato fields during the summer season of 1993 and 1994, in order to study egg parasitism. Only two species were found to parasite C. chalcites and A. gamma eggs: Telenomus sp. (Hym.: Scelionidae) and Trichogramma cordubensis (Hym.: Trichogrammatidae). The natural egg parasitism rates were higher in the first year (62.30% for A. gamma and 48.39% for C. chalcites) than in the second (25.16% for A. gamma and 10.91% for C. chalcites). Telenomus sp. was the parasitoid with higher parasitism rates on both host species. Furthermore, this parasitoid always appeared earlier in the fields than T. cordubensis.engAutographa gamma LChrysodeixis chalcitesSummer SeasonTelenomus sp.Trichogramma cordubensis Vargas & CabelloTomato Fieldsjournal article
