Ultrastructure and heteromorphism of spermatozoa in five species of bugs (Pentatomidae: Heteroptera).
Characteristics derived from the morphology of spermatozoa indicate synapomorphies and are promising for systematic studies, particularly in phylogeny and behavioral issues associated with the presence of polymorphisms. Expand
Notes on Midgut Ultrastructure of Cimex hemipterus (Hemiptera: Cimicidae)
There was strong evidence that the posterior midgut may be the major site of nutrient absorption and the hematophagous heteropteran groups share many of these blood digestion mechanisms. Expand
Ecological Life Table of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
An ecological life table was constructed, aiming to determine the critical stages and key mortality factors of Tuta absoluta (Lepidoptera: Gelechiidae), and Predators were responsible for 79.4% of larval mortality. Expand
Impact of integrated pest management on the population of leafminers, fruit borers, and natural enemies in tomato
IPM was the most efficient system of pest control due to presenting similar productivity and 65.6% less pesticide applications than in the calendar and when action thresholds were achieved. Expand
Social wasps (Hymenoptera: Vespidae) as indicators of conservation degree of riparian forests in Southeast Brazil.
The potential use of social wasps as ecological indicators of habitat quality in riparian forests is verified and species indicator value analysis showed that Pseudopolybia vespiceps and Polybia fastidiosuscula are associated positively to the high conservation degree of the riparian forest. Expand
Morphology of female reproductive tract of the predator Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) fed on different diets
A morfologia do sistema reprodutor feminino de Podisus nigrispinus alimentado com larvas de Alabama argillacea, Musca domestica L. e de Tenebrio molitor L. ou dieta artificial y cada ovario apresentou sete ovariolos unidos pelos filamentos terminais em uma estrutura em forma of cacho. Expand
Nymphal Development and Reproduction of Podisus nigrispinus (Heteroptera: Pentatomidae) Fed With Combinations of Tenebrio molitor (Coleoptera: Tenebrionidae) Pupae and Musca domestica (Diptera:
The development and reproduction of Podisus nigrispinus (Dallas) fed on Tenebrio molitor L. molitor and Musca domestica and females of this predator showed higher egg and nymph production when they received both prey. Expand
Effects of plant feeding on the development, survival and reproduction of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae)
Diets consisting of leaves of cotton and/or water were insufficient to promote the complete development and survival of Podisus nigrispinus (Dallas) to the adult stage, but nymphs fed leaves lived longer than those provided with only water, and feeding on plant material by P. nigris pinus is a potentially positive attribute in biological control against cotton leafworm.

Biochemical and morphological aspects of salivary glands of the predator Brontocoris tabidus (Heteroptera: Pentatomidae)
The aim of this work was to study the feeding habits of the predator Brontocoris tabidus analyzing the salivary gland complex (SGC) and suggested that it could be considered an obligate zoophytophagous. Expand
Effects of diet on development of Podisus nigrispinus (Dallas) (Het., Pentatomidae), a predator of the cotton leafworm
Abstract:  The effects of diet on development of Podisus nigrispinus (Dallas) (Het., Pentatomidae) were studied at 25°C, relative humidity of 60 ± 10%, and photoperiod of 14 h light : 10 h dark.Expand
