Subject:
Anastrepha; species diversity; population distribution; quantitative analysis; insect ecology; insect surveys; Brazil
Abstract:
... The distribution of females of Anastrepha species per trap was strongly clustered, with five traps (6%) capturing 50% of the total of females. Only Anastrepha fraterculus (Wied.) and A. obliqua (Macquart) were dominant species. A. fraterculus was by far the most frequent species (80.2% of the females), and the most constant, occurring in 98.0% of the samples. In decreasing order of frequency, A. o ...

Abstract:
... Several standardized surveys of bee communities undertaken in Brazil in the last few decades have allowed a comparative approach to the search for generalized patterns of community structure. In this paper the results of a standardized year-round bee survey undertaken in Itatim, Northeastern Brazil, in the semi-arid caatinga domain (12* 42'S; 39* 46'W) are presented. The main objective was to inve ...

The genotypes were divided into two plots and set up in a block-randomized design with 20 replications. New expanded bean leaves were sectioned and placed in glass tubes containing distilled water and disposed in acrylic cages containing approximately 500 insects. After 24h, the tot ...

Abstract:
... The tomato leafminer, Tuta absoluta (Meyrick), is one of the key pests of tomato in Argentina. Since its dispersal in the 1970s, chemical control has been the main method of controlling it. However, reduced efficacy of some of the recommended insecticides has been observed since the 1980s. The aim of this work was to study the toxicity of three insecticides widely used in chemical control of T. ab ...

The isolation and maintenance of symbiotic basidiomycete fungi living in association with ants of the tribe Attini has been hindered by the slow growth rate of these fungi and the presence of other microorganisms on the surface of the material which the ants maintain inside their nests to provide a growth substrate for their symbiont. In this paper we describe a method which increases the efficien ...
