Morfología de los estados inmaduros y adulto de Neohydatothripsdenigratus (De Santis) (Thysanoptera: Thripidae), con datos sobre su biología

Abstract

-The adult female of Neohydatothrips denigratus (De Santis) is redescribed, the male and immature stages (larva, prepupa and pupa) are described for the fi rst 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 fl owers or fruits. Under controlled conditions (21 ± 2ºC; 80 ± 4% 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 2:1. 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.

Species-richness in Neotropical Sericothripinae (Thysanoptera: Thripidae)

“…The metanotal striae are similar to those of N. gracilipes and not closely set, with no markings or shadow lines associated with the major striae. N. burungae was found in large numbers on avocado leaves in Mexico and Guatemala (Hoddle et al 2002), and Contreras and Zamar (2010) indicated that the species breeds on Medicago sativa, Phaseolus vulgaris and Solanum esculentum in Argentina (Table 1).…”
