1. Diet of benthivorous fish and prey availability in streams of the Pirapó River basin-PR
Resumo Objetivo O objetivo deste estudo foi avaliar a dieta de sete espécies de peixes que consomem predominantemente macroinvertebrados bentônicos, e a disponibilidade desses organismos no ambiente. Foi analisada a ocorrência de segregação trófica entre as espécies de peixes e a correlação entre a abundância de macroinvertebrados na dieta e no am

2. Gall-inducing insects of restinga areas (Atlantic Forest) in Brazil: economic importance
Abstract Many gall-inducing insects have been reported as pests in the Old World and North America, although few such examples are known from South America. A list of gall-inducing insects of potential economic importance, with a focus on those of restinga environments, was compiled using Maia (2013a) as starting point and updated with the database “Thomps

3. Species Diversity and Community Structure of Arthropod Pests and Predators in Flax, Linum Usitatissimum L. from Darjeeling (India)
ABSTRACT The species richness and relative abundances of different aboveground plant-dwelling pest and predator species were assessed in flax (Linum usitatissimum L.) ecosystem under mid-hill conditions of eastern Himalayas. The experiment was conducted in winter seasons during 2004-2013 at the Regional Research Station (Hill Zone), Uttar Banga Krishi Viswav

4. Do container size and predator presence affect Culex (Diptera: Culicidae) oviposition preferences?
ABSTRACT Organisms with complex life cycles typically do not exhibit parental care. Hence, the ability of adult females to choose quality oviposition sites is critical for offspring success. Gravid females of many insect taxa have the capability to detect environmental conditions in water-holding containers (e.g., resource level, presence of competitors or p

5. Peptidomic analysis of the venom of the solitary bee Xylocopa appendiculata circumvolans
Abstract Background: Among the hymenopteran insect venoms, those from social wasps and bees - such as honeybee, hornets and paper wasps - have been well documented. Their venoms are composed of a number of peptides and proteins and used for defending their nests and themselves from predators. In contrast, the venoms of solitary wasps and bees have not been

6. Pyrrolizidine Alkaloids in the Pericopine Moth Scearctia figulina (Erebidae: Arctiinae): Metabolism and Chemical Defense
Pyrrolizidine alkaloids (PAs) are defensive compounds present in several plant families. However, some specialist herbivore insects have overcome these toxic compounds and sequester PAs converted to N-oxide as a defense against predators and a precursor of male sexual pheromones. In this context, we investigated PA sequestration by the specialist pericopine

7. Insect galls of a protected remnant of the Atlantic Forest tableland from Rio de Janeiro State (Brazil)
ABSTRACT Insect galls of a protected remnant of the Atlantic Forest tableland from Rio de Janeiro State (Brazil): Galling insects in Rio de Janeiro state are known by their great diversity, despite most of the surveys have been done in restinga. This paper investigated the insect galls from a remnant of Atlantic Forest located in São Francisco de Itabapoana

8. Pre-dispersal seed predation and abortion in species of Callisthene and Qualea (Vochysiaceae) in a Neotropical savanna
The ability of plants to generate fertile offspring is influenced by morpho-physiological and ecological factors. Hence, reproductive success is directly linked to factors affecting quantity and quality of their progeny. In the Cerrado (savanna) of Brazil, the Vochysiaceae is a widely distributed and ecologically important family. Factors affecting pre-dispe

9. Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil
Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil. This study carried out an insect gall inventory in restinga areas of Ilha da Marambaia, in the municipality of Mangaratiba, Rio de Janeiro, Brazil. Sampling was carried out monthly from April 2010 to March 2011 along the full extension of seven beaches. A total number of 147 gall mo

10. Effect of the insecticide Lambda-cyhalothrin on rice spider populations in southern Brazil
The adverse effect that insecticides have on spider populations is of major concern since these predators are a component in the biological control of rice insect pest populations. This study was designed to determine the effect of the pyrethroid insecticide, Lambda-cyhalothrin, on spider populations in rice fields. Treatments consisted of plots treated once

12. Morphological, behavioral and biological aspects of Azya luteipes Mulsant fed on Coccus viridis (Green)
One of the major pests of nursery seedlings of coffee (Coffea arabica L.) is the green scale, Coccus viridis (Green) (Hemiptera: Coccidae). The main predators of this species are beetles of the family Coccinellidae, especially Azya luteipes Mulsant. Morphological, behavioral and biological aspects of A. luteipes feeding on C. viridis on coffee plants were ex
