Morfología de los estados inmaduros y adulto de Neohydatothripsdenigratus (De Santis) (Thysanoptera: Thripidae), con datos sobre su biología / Morphology of the immature and adult stages of Neohydatothrips denigratus (De Santis) (Thysanoptera: Thripidae), with data on its biology

ABSTRACT

The adult female of Neohydatothrips denigratus (De Santis) is redescribed, the male and immature stages (larva, prepupa and pupa) are described for the first time, and aspects of the biology of this species are made known. Descriptions of the different stages of development were made from laboratory-reared specimens on using twigs of Phaseolus vulgaris as a feeding and oviposition substrate. Neohydatothrips denigratus undergoes its life cycle on the leaves of P. vulgaris, no immature stages were found in flowers or fruits. Under controlled conditions (21 ± 2ºC; 80 ± 4 percent RH; photophase 12h), this species needed 21.6 ± 1.60 d to complete development (egg 7.0 ± 1.00 larva I 3.7 ± 1.40; larva II 4.2 ± 1.10; prepupa 1.8 ± 0.70, pupa 5 ± 1). Longevity was 6.0 ± 2.00 days and observed sex ratio was 21. From the sixteen plants belonging to ten families recorded as hosts to this species, larvae were found only on two species of Fabaceae and one of Solanaceae.
