The effect of seven natural diets on the development and reproduction of Bonagota cranaodes (Meyrick) was evaluated under laboratory conditions. The experiments were carried out at the temperature of 23 ± 1ºC, with 70 ± 10% of RH and a photoperiod of 16:8h (L:D). The larvae were reared on apple, grapevine and honeysuckle (Lonicera japonica). On the first two foods three types of diet were used: spring leaves, summer leaves and fruits. The number of instars varied from five to seven. The larvae reared on apple leaves had, in general, fewer instars than those reared on grapevine and honeysuckle leaves. The duration of larval development differed between diets. The larvae reared on spring apple leaves showed the shortest duration, and those on fruit the... |

The effect of six natural diets on the development and reproduction of Argyrotaenia sphaleropa (Meyrick) was measured under laboratory conditions, at 23 ±1ºC temperature, 70 ± 10% RH, and photoperiod of 16L:8D. Larvae were reared on three types of diet (spring leaves, summer leaves and fruits) from two different host plants (apple tree and grapevine). Larval development, number of instars, survival, weight of pupae, fecundity, and fertility varied as a function of diets. The shortest time span of larval development, the greatest pupal weight, and the greatest adult fecundity and fertility was observed on insects feeding on spring apple leaves. The duration of larval development was longer on fruits than on leaves. The lowest larval survival occurred on... |
