| Coleoptera associated to undisturbed cattle droppings in pastures present great diversity and abundance. Several species are of primary veterinary importance for they may act as natural enemies of pest insects that breed in this habitat. To survey the diversity and abundance of Coleoptera associated to undisturbed cattle droppings, four undisturbed cattle dung pats naturally dropped in pastures and 5 cm of the soil immediately beneath them were collected almost all weekly from april 1992 to april 1994 in a farm located in the vicinity of São Carlos, State of São Paulo, Southeastern Brazil. Beetles were collected from the pats both using Berlese funnels and by allowing the beetles to emerge for 30 to 40 days. A total of 24,332 specimens belonging to 13... |

| The objectives of this study were to observe the external development of Metarhizium anisopliae and Beauveria bassiana on workers and soldiers of Cornitermes cumulans (Kollar) and to establish comparisons between the insect fixation techniques known as critical point and desiccator. Termite workers and soldiers inoculated with B. bassiana (447) and M. anisopliae (1037) were utilized. After inoculation, the insects were left at 25±0.5°C. In order to make observations, samples from both castes were removed at 0, 6, 12, 24, 48, 72, 96, 120, 144, and 168h after inoculation. The external development of M. anisopliae and B. bassiana conidia on the termite C. cumulans showed that M. anisopliae and B. bassiana conidial germination occurred on several regions of... |

| The spider mite Tetranychus evansi Baker & Pritchard can cause severe damage to tomato crops. The predatory mite Phytoseiulus longipes Evans was recently reported in association with T. evansi in Uruguaiana, Rio Grande do Sul State, Brazil. The objective of the present study was to evaluate the effects of P. longipes on the population of T. evansi on tomatoes under screenhouse condition. The study consisted on four experiments, in each of which 80 potted plantlets were distributed in two plots of 40 plantlets each. Two weeks later, each plantlet of both plots was infested with eight adult females of T. evansi; one week after, four adult females of P. longipes were released onto each plant of one plot. The population levels of T. evansi and the... |

| Mechanisms involved in maintaining colonies of social insects free of pathogens are among the main aspects of interest in the evolutionary biology of this group. For ants, it has been suggested that secretion from the metapleural glands play an important role in colony asepsis. In this study, different worker subcastes of the fungus-growing ant Atta sexdens piriventris Santschi were compared in relation to presence of metapleural secretion during a year. At the same time, the topical activity of the secretion was tested on workers treated with the entomopathogenic fungus Beauveria bassiana (Bals.) Vuillemin. Based on the mean width of the cephalic capsule, six worker subcastes were defined: gardener, minor, media, large, major and soldier. A positive... |

| The occurrence of the tomato red spider mite (Tetranychus evansi Baker & Pritchard) and predatory mites on four of the most abundant native solanaceous plants in coastal Pernambuco, Brazil, was evaluated. Monthly samples were collected from mid September 2002 to late May 2003 in Aliança, Carpina, Camaragibe, Goiana, Igarassu and Recife. A total of 5,485 mites of more than 27 species were found, of which the most common were the phytophagous species T. evansi and Brevipalpus phoenicis (Geijskes) (Tenuipalpidae), and the predaceous species Asca sp. (Ascidae), Phytoseius guianensis De Leon and Paraphytoseius orientalis (Narayanan, Kaur & Ghai) (both Phytoseiidae). Negative indexes of association were determined between T. evansi and each of... |

| The objective of the present study was to estimate the rates of parasitism of Lysiphlebus testaceipes (Cresson) on Schizaphis graminum (Rond.) and Aphis gossypii Glover under choice and no-choice condition tests. The experiments were carried out in a controlled environmental chamber at 25±1ºC temperature, 70±10% RH, and 12h photophase. Second and third instar aphid nymphs were used as hosts and for each colony one less than a day old L. testaceipes female was used. The previously mated and oviposition inexperienced female remained in contact with the hosts for 24 h. In the choice test 10 colonies of S. graminum and 10 colonies of A. gossypii having sections of sorghum leaves as substrate were used. For the no-choice test 10 colonies of S. graminum... |

| The pathogenicity of six entomopathogenic nematodes was assessed against nymphs of the sugarcane root spittlebug Mahanarva fimbriolata (Fabr.), in the laboratory. The efficiency of the most virulent agent was tested in the field. Seven laboratory treatments were designed with two specimens of the genus Heterorhabditis, three of Steinernema, one specimen of Steinernema glaseri (Steiner), and a control group. In the field, two experiments were conducted. The first experiment involved nine treatments: the control, four treatments with Heterorhabditis sp. (CB-n5) applied to the straw mulch at doses 6.6 x 10(7), 3.3 x 10(8), 6.6 x 10(8) and 3.3 x 10(9) IJs/ha, and four treatments with the nematodes applied to the soil and beneath the straw mulch layer, at the... |

| Phymastichus coffea LaSalle is an African endoparasitoid of adults of the coffee berry borer, Hypothenemus hampei (Ferrari) that was introduced into Mexico for biological control purposes. The objective of this study was to investigate the oviposition behavior of P. coffea on its host under laboratory conditions. The results indicate that P. coffea females exhibited 12 behavioral acts during and after oviposition, such as, walking, cleaning, flying, surface landing, resting, host landing, host antennation, touching the host with forelegs, host recognition, walking on the host, oviposition and cleaning after oviposition. The sequence of each behavior is described in an ethogram. |

| The lady beetle Coleomegilla maculata (De Geer) is a natural enemy of several insect pests and feeds on pollen and nectar to survive periods when prey is scarce. The effect of the feeding interval on the development, survival, fecundity, and longevity of C. maculata was determined. Newly hatched larvae of C. maculata were reared individually and fed with eggs of the Mediterranean flour moth Anagasta kuehniella (Zeller) at intervals of one, two, and three days under controlled conditions (23 ± 1ºC; 60 ± 10% RH; 12 h phtophase). The duration of larval instars and the total larval stage was prolonged as the feeding interval increased. The larval period lasted on average 9.2 ± 0.19 days when the larvae were fed daily with prey, and 14.6 ± 0.48 days when food... |

| Cell hypertrophy was the first reaction of the gut epithelial cells of Aedes aegypti (L.), Anopheles albitarsis (Lynch-Arribálzaga) and Culex quinquefasciatus (Say) to the toxins of strains 2362 and S1116 of Bacillus sphaericus, as cells had an increase of intracellular secretory activity. Soon after the cell hypertrophy developed, vesicles were formed at the cell apical portion, which detached with the plasma membrane, characterizing a type of apocrine secretion like. The first pathway of contamination of the mosquito larvae by these bacteria is through the gut, by feeding. Depending on the species of Culicidae and on the bacterial strain used, the hypertrophy of the gut epithelium occurred between 5 and 15 min after exposure to the contaminated... |
