The ability of Trichospilus diatraeae Cherian and Margabandhu, 1942 (Hymenoptera: Eulophidae) to search and parasitize Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) pupae in sugarcane stalks was evaluated. To analyze the ability for search and parasitism were used stalks of sugarcane (20 cm) where it was introduced a pupa of D. saccharalis (T1); a pupa and a caterpillar (T2) or a pupa and fecal matter (T3). Each stalk was placed in a transparent plastic bottle with 21 females of T. diatraeae. These pupae were isolated, after 72 h, in glass tubes at 25 ± 2 °C, 70 ± 10 % relative humidity, 14:10 light/dark. The experiment was developed in an entirely casualized design with three treatments and 12 repetitions. Percentage of D. saccharalis... |

O presente trabalho teve por objetivo avaliar a ação residual dos produtos etofemprox, fenitrotiom, metidatiom e triclorfom sobre adultos de Trichogramma pretiosum, bem como sobre as gerações F1 e F2 desse parasitóide, em condições de laboratório. Ovos do hospedeiro alternativo Anagasta kuehniella (Zeller) (Lep., Pyralidae) foram aderidos em cartelas de cartolina azul, inviabilizados sob lâmpada germicida e tratados por imersão nas soluções inseticidas e em água destilada (testemunha) por cinco segundos. Os ovos foram expostos ao parasitismo uma, 24 e 48 horas após o tratamento, por um período de 24 horas, e posteriormente mantidos em câmara climatizada a 24±1ºC, UR de 70±10% e 12 horas de fotofase até a emergência dos parasitóides.... |

The present research aimed to elucidate which aspects of immune responses in Diatraea flavipennella are suppressed by the parasitoid Cotesia flavipes, thus, ensuring parasitism success. We investigated the presence of apoptosis in fat body cells through the TUNEL technique. According to the results, reduced levels of nitric oxide and phenoloxidase activity were observed in larvae parasitized for three days, and reduced total number of hemocytes, after three and seven days. An increase in plasmatocytes and decrease in spherulocytes numbers were observed in the differential count on the third day of parasitism. The number of melanized microspheres in parasitized larvae was low and indicated less intense melanization. The ultrastructural analysis confirmed... |

The effect of the hyphomycete Paecilomyces fumosoroseus (Wise) Brown & Smith on the predatory and parasitic activity of Aphelinus asychis Walker, a common parasitoid of the Russian wheat aphid, Diuraphis noxia (Mordvilko), was investigated under three different humidities. Three cohorts of 20 female A. asychis were treated with 5.2 x 10(4) spores/cm² (twice the LD95 for D. noxia). Each female was then individually maintained in a ventilated Petri dish in which were placed three barley leaves and 20 third-instar D. noxia. Cohorts of 20 treated females were each held at one of the following relative humidities along with an equal number of untreated control insects: 67-73%, 85-89%, and 94-98%. Every 24 hours over a period of one week, the surviving... |

Este estudo determinou as espécies de hospedeiros do parasitóide Paraganspis egeria (Díaz, Gallardo & Walsh, 1996) (Hymenoptera: Figitidae) em esterco bovino, fezes humanas, rins de bovino, galinha e carcaça de suíno. As pupas foram obtidas pelo método de flutuação. Elas foram colocadas individualmente em cápsulas de gelatina e mantidas até a emergência das moscas e/ou parasitóides. A prevalência total de parasitismo foi de 3,4%. |

Abstract In Argentina, five galling species of the family Cecidosidae (Lepidoptera), including Cecidoses eremita Curtis and Eucecidoses minutanus Brèthes, have been cited. This note reports a preliminary study of their galls in "molles" (Schinus longifolius (Lindl.) Speg.) of Magdalena (Buenos Aires, Argentina). In April 2013, galls of C. eremita and E. minutanus were censused in randomly selected "molles". In April and December 2013, randomly selected galls were then collected and transported to our laboratory in hermetic bags, and conserved at -18 ºC until examination. Maximum diameter and wall thickness of collected galls were measured. About 84% of the observed "molles" (103/123) had galls of C. eremita and/or E. minutanus. The median of galls per tree... |

This is the first study about galls, gall makers and associated fauna of the Ecological Station of Jataí. Galls are plant structures formed by abnormal growth of cells, tissues or organs induced by several organisms, as fungous, nematoids and insects. Five areas of the conservation unity, two in the phytophysionomy of cerrado in regeneration and three in the cerradão area were studied, totalizing 69 morphotypes of galls on 41 host species from 24 families. This is the first record of Annonaceae as the richest family in morphotypes in Brazil; 34 gall makers and associated fauna were identified, which 23 Diptera (67.4%), eight Hymenoptera (23.5%), two Hemiptera (5.8%) and one Thysanoptera (2.9%). Were described 41 new morphotypes of gall and made the first... |

Pupae of Thyrinteina arnobia (Stoll) and Thyrinteina leucoceraea Rindge (Lepidoptera: Geometridae) were obtained from Eucalyptus cloeziana F. Muell and Eucalyptus urophylla S.T. Blake plants, respectively. Specimens of a parasitoid emerged from T. arnobia pupae and also found parasitising T. leucoceraea pupae in the field were identified as Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae). This is the first report on P. elaeisis parasitizing T. arnobia and T. leucoceraea pupae in natural conditions in Brazil. P. elaeisis also parasitized these hosts and Bombyx mori Linnaeus (Lepidoptera: Bombycidae), Anticarsia gemmatalis Hubner, Pseudaletia sequax Franclemont, Alabama argillacea Huebner (Lepidoptera: Noctuidae), Dirphia moderata Bouvier... |

Corn (Zea mays L.) is cultivated in large areas and considered one of the world's major cereal crops. There are several arthropod pests that can reduce its production such as the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lep.: Noctuidae), which is considered to be the main pest for corn. Fall armyworm is primarily controlled by insecticides. The use of biological control agents to manage this pest is growing with an emphasis on the egg parasitoid Trichogramma pretiosum Riley (Hym.: Trichogrammatidae). Thus, the aim of this research was to evaluate the impact of the following insecticides (g ai L-1) beta-cypermethrin (0.03), chlorfenapyr (0.60), chlorpyrifos (0.96), spinosad (0.16), etofenprox (0.10), triflumuron (0.08),... |

ABSTRACT: From those of the mealybug family, the citrus mealybug, Planococcus citriRisso, 1813 (Hemiptera: Pseudococcidae) is frequently held responsible for various diseases occurring in vineyards. This is a first time report in Brazil, on the occurrence of a parasitoid controlling P. citri. In our search for the natural enemies of P. citri, bunches of grapes with the vine were collected every week for one month, in those regions where table grapes were produced, like Petrolina, Pernambuco, Brazil. In these samples, among the natural pest infestations Coccidoxenoides perminutusGirault, 1915 (Hymenoptera: Encyrtidae) was the only natural enemy species reported. In this research, we attempted to study the potential of parasitism as well as the strategies... |

The oviposition behaviour of Gryon gallardoi (Brèthes, 1914) on eggs of Spartocera dentiventris Mendonça Jr. (Berg, 1884) of different ages (2, 3, 4, 5, 6, 7, 8 and 12 days) was investigated. Groups of 12 eggs of each age were exposed to single females of G. gallardoi, and the oviposition behaviour was recorded under a stereomicroscope for two hours. Ten replicates were used for each age. In order to identify the moment the parasitoid egg was released inside the host, 1-day old eggs of S. dentiventris were exposed to G. gallardoi females, and the oviposition was interrupted at intervals of 20, 40, 60, 80, 100, 120, 140 and 160s after ovipositor insertion had initiated. Five behavioural steps were recorded: drumming, ovipositor insertion, marking, walking... |
