| 6-phosphofructo-1-kinase (phosphofructokinase; PFK) activity from Rhodnius prolixus, a haematophagous insect which is usually a poor flyer, was measured and compared in two metabolically active tissues - flight muscle and fat body. The activity of this important regulatory glycolytic enzyme was much more pronounced in muscle (15.1 ± 1.4 U/mg) than in fat body extracts (3.6±0.4 U/mg), although the latter presented higher levels of enzyme per protein content, as measured by western-blotting. Muscle extracts are more responsible than fat body to ATP and fructose 6-phosphate, both substrates of PFK. Allosteric regulation exerted by different effectors such as ADP, AMP and fructose 2,6-phosphate presented a singular pattern for each tissue. Optimal pH (8.0-8.5)... |

| New species of bat-ectoparasite insects are added to the fauna of Argentina and distributional limits are extended for others, based on information obtained from 21 species of bats collected. New data is reported for the distribution of 23 species of bat ectoparasites, of which 17 belong to the Order Diptera [14 Streblidae: Anastrebla caudiferae Wenzel, Anatrichobius scorzai Wenzel, Aspidoptera phyllostomatis (Perty), Megistopoda aranea (Coquillett), M. proxima (Sèguy), Metelasmus pseudopterus Coquillett, Noctiliostrebla aitkeni Wenzel, N. dubia (Rudow), Paradyschiria fusca Speiser, Paradyschiria sp., Strebla chrotopteri Wenzel, Strebla diaemi Wenzel, Trichobius parasiticus Gervais y Xenotrichobius noctilionis Wenzel, and three Nycteribiidae: Basilia... |

| Durante dois anos, de junho/93 a maio/95, contagens de moscas-dos-chifres foram realizadas em dois rebanhos Nelore criados extensivamente na fazenda Nhumirim, sub-região da Nhecolândia, Pantanal, MS. Os rebanhos possuíam 40 e 60 vacas, mantidas sem tratamento inseticida durante o estudo. Contagens foram realizadas duas semanas consecutivas por mês, por observadores a cavalo, em pelo menos 50% dos animais em cada rebanho. Foram observados dois picos populacionais anuais da mosca, após o início (novembro/dezembro) e final (maio/junho) do período chuvoso. A presença de moscas foi observada durante todo o estudo, em pelo menos 64% dos animais. Infestações médias não excederam 85 moscas/animal e permaneceram abaixo de 35 moscas/animal na maior parte do estudo.... |

| De junho/92 a maio/94, capturas de mutucas foram realizadas mensalmente em eqüino e utilizando armadilhas do tipo ?canopy?, na fazenda Nhumirim, subregião da Nhecolândia, Pantanal sul-mato-grossense. Capturas no eqüino foram realizadas do crepúsculo matutino ao vespertino, com o auxílio de redes entomológicas, em ambientes de campo e cerradão (1 dia/ambiente/mês), durante o primeiro ano do estudo. Capturas com armadilhas foram realizadas nos mesmos ambientes (10 dias/ambiente/mês), por dois anos. Foram capturadas 6.274 mutucas ao longo do estudo, pertencentes a 25 espécies, 13 gêneros e 3 subfamílias. A espécies mais abundantes foram Tabanus importunus (44,04%), Tabanus occidentalis (15,95%), Tabanus claripennis (9,98%) e Lepiselaga crassipes (7,60%).... |

| Porphyrosela minuta Clarke is a gracillariid that causes damage on white clover (Trifolium repens) in Uruguay. In this article, the eggs, all the larval instars, the pupa and the external morphological characteristics of the adult are described. Information about the insect's biology under laboratory and field conditions is presented. The eggs are laid singly on the upper surface of the leaflets. The larvae make extensive mines that appear as white blotches. The larvae develop through five instars and do not remain exposed during their development. At 25ºC the life cycle lasted 16.2 days, made up of 3.0 for eggs, 8.8 for larvae and 4.4 for pupae. Females began laying on the first night, and during an oviposition period that varied between five and 12 days... |

| ABSTRACT Bactrocera carambolae is a quarantine pest found in Brazil, restricted to the states of Amapá, Pará and Roraima. This fruit fly can potentially cause extensive socioeconomic and environmental damage in the country, if it disperse into areas where fruit is grown for exporting. The objective of this work was to study the biology of B. carambolae on fruits of Averrhoa carambola L. (Oxalidaceae), Psidium guajava L. (Myrtaceae), Spondias mombin L. (Anacardiaceae) and Eugenia stipitata McVaugh (Myrtaceae). The following parameters were investigated: duration of egg-larva, pupal, egg-adult, pre-oviposition, oviposition and post-oviposition periods, pupal weight and viability, sex ratio, fecundity, fertility and longevity. All parameters except pupal... |

| Many insects host facultative, bacterial symbionts that confer conditional fitness benefits to their hosts. Hamiltonella defensa is a common facultative symbiont of aphids that provides protection against parasitoid wasps. Protection levels vary among strains of H. defensa that are also differentially infected by bacteriophages named APSEs. However, little is known about trait variation among strains because only one isolate has been fully sequenced. Generating complete genomes for facultative symbionts is hindered by relatively large genome sizes but low abundances in hosts like aphids that are very small. Here, we took advantage of methods for culturing H. defensa outside of aphids to generate complete genomes and transcriptome data for four strains of... |
