1. Can body traits, other than wings, reflect the flight ability of Triatominae bugs?
Abstract: INTRODUCTION : Insects of the subfamily Triatominae are vectors of Trypanosoma cruzi , the Chagas disease parasite, and their flying behavior has epidemiological importance. The flying capacity is strikingly different across and within Triatominae species, as well as between sexes or individuals. Many Triatoma infestans individuals have wings but

2. Percevejos castanhos (Hemiptera, Cydnidae, Scaptocoris): aspectos morfológicos, ecológicos e comportamentais / Burrowing bugs (Hemiptera, Cydnidae, Scaptocoris): morphological, ecological and behavioral aspect
The objective of this study was to elucidate morphological, ecological and behavioral aspects of the burrowing bugs (Scaptocoris). Population dynamic studies, sexual dimorphism, wing polymorphism, and acoustic communication were investigated on different species of Scaptocoris. Studies on population dynamics and vertical distribution in the soil were carried

3. Morphometric analysis of Triatoma dimidiata populations (Reduviidae:Triatominae) from Mexico and Northern Guatemala
Triatoma dimidiata is one of the major vectors of Chagas disease in Latin America. Its range includes Mexico, all countries of Central America, Colombia, and Ecuador. In light of recent genetic analysis suggesting that the possible origin of this species is the Yucatan peninsula, we have analyzed populations from the state of Yucatan, San Luis Potosi, and Ve

4. Insect juvenile hormone: from "status quo" to high society
Juvenile hormone (JH) exerts pleiotropic functions during insect life cycles. The regulation of JH biosynthesis by neuropeptides and biogenic amines, as well as the transport of JH by specific binding proteins is now well understood. In contrast, comprehending its mode of action on target organs is still hampered by the difficulties in isolating specific rec

5. Criação, biologia e aspectos da genetica do polimorfismo alar de cigarrinhas-das-pastagens (homoptera: cercopidae)
This study involves the development of spittlebug rearing methods which made possible analysis of the biology and genetics of three different species of this insect. The studied species included Deois sp., Deois schach and Deois flavopicta. The biological parameters analysed were length of mating, longevity, pre-oviposition and oviposition period, fecundity,

6. Cigarrinhas das pastagens (Homoptera, Cercopidae) : distribuição geografica e variabilidade genetica
The present work is the result of a survey on the geographic distribution, wing and enzymatic polymorphism, followed by some "information on the biology of several froghopper species found in Brazilian pastures. Among these species four were analyzed in closer de-tail: Deois schach (Fabr., 1787); Deois flavopicta (Sta1, 1854); Deois sp. e ZuZia entreriana (B

7. Metabolic resource allocation vs. mating attractiveness: Adaptive pressures on the “alba” polymorphism of Colias butterflies*
The sex-limited “alba” genetic polymorphism in wing color of Colias butterflies has been studied with respect to potential selective pressures on this locus. Alba female pupae, carrying at least one dominant A allele, redirect resources, used by aa pupae for pigmentation, to other metabolic ends. Associated with this reallocation, alba, A-, female adults

8. ADAPTIVE SIGNIFICANCE OF PIGMENT POLYMORPHISMS IN COLIAS BUTTERFLIES, II. THERMOREGULATION AND PHOTOPERIODICALLY CONTROLLED MELANIN VARIATION IN Colias eurytheme
The butterfly Colias eurytheme requires body temperatures above 30°C for flight. When cold, it orients its exposed wing undersides to present maximum surface area to sunlight; when too warm, it orients for minimum exposure. Dark-winged color forms heat faster in sunlight than light ones. The seasonal color polymorphism of Colias appears to have been evolved
