| Discovery of male morphological characters for species identification was a great improvement in Trichogramma systematic. However, not all species could be easily identified. In some cases, the lack of males (thelytokous status of species that carry the Wolbachia symbiont) made Trichogramma identification impossible. This problem was solved via antibiotic and heating treatments for elimination of the bacteria and allowing the production of males. The only Trichogramma species reported in which thelytoky is not induced by bacterial infection is T. cacoeciae, so here another means of species identification is needed. This species was identified based on the ITS2 (Internal transcribed spacer 2) sequence, a modern technique that has been proved useful in... |

| 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... |

| 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 larval ectoparasitoid Euplectrus ronnai (Brèthes) is one of the components of a species complex that attacks the armyworm Mythimna (Pseudaletia) sequax Franclemont (Lepidoptera: Noctuidae). No data are available on the fecundity, longevity and host instar preference of E. ronnai, what prompted the conduction of this research. No parasitism occurred on the first and sixth instars of the host, and a positive relationship was found between host instar and the number of parasitoid eggs/host, which ranged from 1.5 on third- instar hosts to 3.6 on fifth instars. Females of E. ronnai showed a preference for either the fourth or fifth instar of M. sequax. There were no significant differences in the developmental time of the parasitoid, sex ratio, mean number... |

| Abstract Parasitoids manipulate the host metabolism for their own benefit by influencing its development and the direct or indirect result of it is the host death. This study aimed to observe the influence of parasitoidism of Paravilla sp. (Diptera, Bombyliidae) on the development of antlion larvae Myrmeleon brasiliensis (Návas, 1914) (Neuroptera, Myrmeleontidae). The specific objectives were to verify in which larval instars the parasitoid oviposition occurs, the influence of the parasitoid on the larval and pupal development time of M. brasiliensis, the differences in body length of the antlion larvae, as well as of the sex ratio of M. brasiliensis adults. For this, the larvae were differentiated in 1st, 2nd and 3rd instar and measures on body length... |

| Abstract: The objective of this work was to determine the biological parameters and thermal requirements of Trichogramma pretiosum TM strain reared on Helicoverpa armigera eggs. A card containing 20 eggs of H. armigera was offered for each T. pretiosum female, at temperatures of 18, 20, 22, 25, 28, 30 and 32°C. All life stages of T. pretiosum were observed under the given temperature conditions. The optimum temperature for the parasitism of T. pretiosum was 25°C, and the highest longevity was found at the same temperature. The highest parasitoid emergence rates occurred at temperatures of 22, 25 and 28°C. The highest proportion of T. pretiosum individuals emerged per egg was observed at 18°C. Concerning the sex ratio, the highest proportion of females... |

| ABSTRACT: Information on selective herbicide, including glyphosate that does not affect non-target organisms such as natural enemies, are important in integrated pest management programs in maize. The dose 13.94 L ha-1 of glyphosate was evaluated in females on 10 Trichogrammatidae species. A female of each Trichogrammatidae species was individually positioned per test tube with a card containing approximately 45 Anagasta kuehniella Zeller, 1879 (Lepidoptera: Pyralidae) eggs. For 48 h parasitism was allowed, and later the cartons were sprayed with the herbicide or with distilled water, for the control treatment. The glyphosate showed variable effects for parasitoids. The emergence of T. acacioi females was lower but that of T. atopovilia, T. demoraesi, and... |

| ABSTRACT This is the first report of Cotesia scotti (Valerio and Whitfield) comb. nov. in Brazil, attacking larvae of the black armyworm, Spodoptera cosmioides, and the southern armyworm, S. eridania. The moth larvae were found respectively, infesting a protected cropping of organic tomato in Hidrolândia, Goiás, Brazil, and a transgenic soybean crop in São José dos Pinhais, Paraná, Brazil. Biological, molecular and morphological characters were used to confirm the identity of the specimens. Parasitoid identification presented a challenge since the species has most diagnostic characters of the genus Cotesia Cameron, but few in the poorly defined genus Parapanteles Ashmead. Based on morphological and molecular evidence, we transfer Parapanteles scotti to the... |

| The geographic ranges of Heimbra opaca (Ashmead, 1894), H. bicolor Subba Rao, 1978 and H. parallela Stage & Snelling, 1986 are extended based on study of material deposited in the entomological collections of the Laboratório de Sistemática e Bioecologia de Parasitoides e Predadores da APTA (Ribeirão Preto, SP, Brazil) of the Instituto Brasileiro de Geografia e Estatística (Brasília, DF, Brazil). Symbra potiguara Perioto & Fernandes sp. nov. (Hymenoptera, Eurytomidae) is described, illustrated and compared with S. cordobensis Stage & Snelling, 1986, the single species previously known for this genus. A key to the genera of Heimbrinae and to the species of Symbra is provided. |

| Specimens of the aphid parasitoid, Binodoxys brevicornis (Haliday, 1833), were reared from the mummies of Cavariella aegopodii (Scopoli, 1763) collected on Foeniculum vulgare (Apiaceae) at the Campus of the Universidade Federal de Lavras, in the city of Lavras, Minas Gerais State on September/2002. This is the first record of B. brevicornis in Brazil. |
