Abstract
CASAS LEAL, Nelson Enrique; RESTREPO SALAZAR, Edwin Fernando; VALLEJO CABRERA, Franco Alirio and ESTRADA SALAZAR, Edgar Iván. Development of an artificial infestation methodology of tomato plants with the fruit borer. Acta Agron. [online]. 2008, vol.57, n.4, pp.259-261. ISSN 0120-2812.
Two tomato plants (S. lycopersicum cv. Maravilla) pruned to two stems with females of Neoleucinodes elegantalis (one, two, four, six adults, and the control) were enclosed in cages (1.5 x 1.5 x 1.8 m) under the randomized complete block design. The treatments were replicated four times. The variables fruit by fruit borer (%) and mean number of entrance holes of fruit borer per fruit were evaluated per plant. Only the variable affected fruit by fruit borer (%) presented significant differences between treatments. The affected fruits were increased in 5.29% by every female introduced into the cage. If it is needed to get fruits losses similar to those seen in very susceptible commercial plots (50-60%) six female must be introduced into the cage.
