Abstract

A method is described for rearing the so-called sugarcane rootstalk borer weevil, Diaprepes abbreviatus (L.), on an artificial diet, and its biology on this diet is reported. Females and males emerged after a mean of 381 ± 4.7 days and 382 ± 6.4 days, respectively. The mean number of eggs per mass was 69.2 ± 7.8; the mean number of eggs deposited per female was 6517 ± 931.1. Females lived a mean of 147 ± 17.1 days, and males 135 ± 21.5 days. Virgin females produced a mean of 1910 ± 349.3 eggs. Most larval hatch occurred 7-8 days after oviposition, with the longest incubation period being 15 days. Hatchling larvae were able to survive for 53 days with adequate moisture. /// Se describe un método de criar Diaprepes abbreviatus (L.) sobre una dieta artificial, y se relata su biología sobre esta dieta. Las hembras y los machos nacen después de un promedio de 381 ± 4.7 y 382 ± 6.4 dias, respectivamente. El promedio de huevos en cada masa fué 69.2 ± 7.8; el promedio de huevos depositados por cada hembra fué 6517 ± 931.1. Las hembras vivieron un promedio de 147 ± 17.1 dias, y los machos 135 ± 21.5 dias. Las hembras vírgenes producieron un promedio de 1910 ± 349.3 huevos. La mayoría de las larvas nacieron 7-8 dias después de oviposicion, y el período más largo de incubación duró 15 dias. Con suficiente humedad las larvas recién naicdas pudieron sobrevivir por 53 dias.
