RESISTANCE OF PINEAPPLE CULTIVARS TO THE FRUIT BORER (THECLA BASILIDES GEYER) IN THE CHANCHAMAYO, PERU |
| Authors: | S. Amez, H. Otiniano |
| Abstract:
A study was carried out from march to september 1992 at the INIA Chanchamayo - San Ramón experimental station in order to evaluate the damage by the "pineapple fruit borer" (Thecla basilides Geyer) on two local cultivars: ‘Samba de Chanchamayo’ and ‘Roja Trujillana’ (‘Trujillo red’), and the introduced ‘Smooth Cayenne’. The number of ovipositions on the inflorescences, the damage caused and the insect mortality were evaluated at different periods. The Thecla lays its eggs on all three cultivars, but fruit evaluations showed that both local cultivars were not damaged, except for some minor nibbling of flowers and flower bracts, the larva being unable to penetrate into the fruit as it does on ‘Smooth Cayenne’, drilling holes and causing full misshaping. | |
