Description
Summary:Female Diaprepes abbreviatus L. were presented with immature citrus leaves, mature citrus leaves, and doubled strips of various substances as potential oviposition sites. In both the laboratory and in caged outdoor experiments more egg masses were deposited between freezer paper strips than between mature leaves. No egg masses were deposited between immature leaves. Artificial substrates were preferred in the following order: freezer paper > waxed paper > transparency film. In emergence experiments utilizing freezer paper with the plastic-coated side out as the oviposition substrate, no neonate larvae escaped from 65% of the egg masses. In contrast, larvae easily escaped from egg masses laid between strips of the other substrates tested. In the field, wax paper and freezer paper were preferred as oviposition sites 43:1 and 50:1 over mature leaf pairs, respectively. These data suggest a new prototype monitoring trap for this weevil. /// Se presentaron a hembras de Diaprepes abbreviatus L. hojas jóvenes y maduras de cítrico y franjas dobles de varios tipos de papel como sitios potenciales para oviposición. Tanto en experimentos en el laboratorio como dentro de jaulas en el campo, más huevos fueron depositados entre las tiras de papel para congelar que entre las hojas maduras. Ninguna masa de huevos fué depositada entre las hojas jóvenes. Los substratos artificiales fueron preferidos en el orden siguiente: papel para congelar > papel encerado > papel de transparencias. En experimentos de surgimiento utilizando papel para congelar (con la cubierta plástica hacia el exterior), ninguna larva neonatal se escapó del 65% de las masas de huevos. Por el contrario, las larvas se escaparon fácilmente de las masas de huevos depositadas entre las tiras de los otros substratos. En experimentos hechos en el campo, el papel encerado y el papel para congelar fueron preferidos sobre las hojas maduras como sitios de oviposición a razón de 43:1 y de 50:1, respectivamente. Estos datos sugieren un nuevo prototipo de trampa para el monitoreo de este picudo.
