Effects of Adult Feeding on the Reproduction and Longevity of Noctuidae, Crambidae, Tortricidae and Elachistidae Species
ABSTRACT - This research evaluates the effect of the adult diet on the reproduction of Anticarsia gemmatalis Hübner, Heliothis virescens (Fabr.), Spodoptera frugiperda (J. E. Smith) (Noctuidae),
Diatraea saccharalis (Fabr.) (Crambidae), Gymnandrosoma aurantianum Lima (Tortricidae) and
Stenoma catenifer Walsingham (Elachistidae). Adults of all species were fed either water or a 10% honey solution. The egg viability for the 1st and 2nd egg masses, adult fecundity, longevity, number of mating and the ovigeny index (OI) (degree of ovarian maturation) were evaluated. Fecundity of
A. gemmatalis and H. virescens was drastically reduced when females were fed only on water. Egg viability from both 1st and 2nd egg masses was variable between treatments. Females of A. gemmatalis,
H. virescens and S. frugiperda, and males of some species had a reduced longevity when fed only on water. The number of matings was higher for A. gemmatalis and D. saccharalis when fed on water only. The OI was < 1.0 for all species evaluated indicating that all females may develop new oocytes as they age. Based on the OI and the reduced fecundity of A. gemmatalis and H. virescens, one observes that adult feeding is important for the reproduction
