Descrição de Brontostoma doughertyae sp. nov. e estudo morfológico comparativo com B. rubrum (Amyot & Serville, 1843) (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae)

Brontostoma doughertyae n. sp. (Hemiptera-Heteroptera: Reduviidae: Ectrichodiinae), from Espirito Santo and Bahia States, Brazil is described based on male specimens. A comparative analysis between the phallic structures of Brontostoma rubrum (Amyot & Serville, 1843) and B. doughertyae sp. nov. is presented. Three structures are important to distinguish them: the gonoporal process (PrG); support of the phallosoma (SPh) and the phallosoma (Ph). A key for the brazilian species of Brontostoma is presented.

The first records of Saica apicalis Osborn & Drake, 1915 and Pseudosaica florida (Barber, 1953) for Brazil are presented. Taxonomical notes on Saica Amyot & Serville, 1843 and Pseudosaica Blinn, 1990 are given.

Associação de moscas-das-frutas (Diptera: Tephritidae) com a "meleira do mamoeiro" (Carica papaya L.)

Since 1988, the medfly Ceratitis capitata (Wiedemann) was described infesting papaya (Carica papaya) cv. Sunrise Solo in North of the State of Espirito Santo, Brazil. Two experiments were carried out to determine the infestation of C. capitata and Anastrepha obliqua (Macq.) in papaya fruit, healthy and infected by sticky disease. In the 1st experiment (forced infestation), no infestation of C. capitata in the healthy fruits was observed, and 60.6 pupae/fruit were obtained in the infected fruit. For A. obliqua, the infestation index was 10.3 and 72.4 pupae/fruit for healthy and infected fruit respectively. In the 2nd experiment (inoculated eggs), the infestation index for C. capitata was 4.0 and 6.3 pupae/fruit and for A. obliqua 10.1 and 10.4 pupae/fruit, for healthy and infected fruit respectively. The high suscetibility of green fruit of papaya infected by sticky disease for C. capitata and A. obliqua was discussed

Infestação natural de Anastrepha spp. (Diptera: Tephritidae) em umbu-cajá no Município de Cruz das Almas, Recôncavo Baiano

The objective of this work was to quantify the natural infestation, pupal survival and fruit fly species associated to fruits of Spondias sp. in the Reconcavo Baiano, State of Bahia, Brazil. From March to July, 2002, 49 samples of fruits were collected with the total of 4,095 fruits and a biomass of 74.4kg. About 30,579 fruit fly puparia were obtained from which 37.4% yielded adults. Anastrepha obliqua (Macquart) (99.6%) was the dominant species, followed by A. fraterculus (Wied.) (0.24%) and A. sororcula Zucchi (0.17%). The infestation index was 410,7 pupae for kilogram of fruits and 7.5 pupae per fruit.

Brontostoma bahiensis sp. nov. de Ectrichodiinae (Hemiptera, Heteroptera, Reduviidae) do Estado da Bahia, Brasil

A new species of the genus Brontostoma Kirkaldy, 1904, from the State of Bahia, Brazil, is described.

Caprilesia gen. nov. and C. almirantiana sp. nov. (type species) are described from Brazil, Bahia. Illustrations of the holotype and also a key for the American genera of Saicinae are presented.

Synopsis of the Chryxinae (Hemiptera, Reduviidae)

Synopsis of the Chryxinae with keys to the genera and species of the subfamily are presented. Chryxus bahianus sp. nov. and the male of Wygodzinskyella travassosi (Lent & Wygodzinsky, 1944) are described.

Telenomus (Hymenoptera: Scelionidae), Egg Parasitoid Of Caligo Brasiliensis (C. Felder, 1862) (Lepidoptera: Nymphalidae) In Southern Brazil

Caligo brasiliensis (C. Felder, 1862) (Lepidoptera: Nymphalidae: Morphinae: Brassolini) (Casagrande, 2004), is a common butterfly in southern Brazil. The larvae feed on leaves of Musa argentea L., Musa sapientum L., Musa parasidiaca L. (Musaceae), Hedychium coronarium Koen. (Zingiberaceae) and Euterpe edulis Mart. (Palmae) according to Silva (1907), Silva et al. (1968) and D’Abrera (1987). Caligo spp. larvae, sometimes, are even abundant enough to be considered as a pest on banana plantations (Hogue, 1993) but rarely reaching economic importance (Fancelli et al., 1998). Nevertheless, Malo and Willis (1961) suggested that Caligo eurilochus (Cramer, 1775), a very close species of C. brasiliensis, in the absence of effective natural biological control, could easily become a serious banana pest. Information about egg parasitoids of Caligo spp. is scanty. In banana plantations particularly, the attack of the trichogrammatid species related to Xenufens ruskini Girault, 1915 is recorded for C. eurilochus in Ecuador (Malo and Willis, 1961); Xenufens ruskini for Caligo memnon (C. Felder et R. Felder, 1867). In Honduras and Colombia the attack of the encyrtid Ooencyrtus caligo Noyes is the record for Caligo illioneus (Cramer, 1775) eggs (Noyes, 1985) and Ooencyrtus sp. in eggs collected in Costa Rica (Harrison, 1963). There is no record about Caligo brasiliensis egg parasitoids in literature. Johnson (1984) established eleven host-specific groups of Telenomus Haliday: T. tabanivorus from Diptera, T. californicus, T. arzamae, and T. dalmanni species group complex from Lepidoptera, T. floridanus, T. crassiclava, T. podisi, T. phymatae, T. laricis, T. nigricoxalis from Hemiptera, and T. longicornis with host unknown. From Brazil, several species of Telenomus californicus species group (Johnson, 1984) were recorded as endoparasitoids of lepidopteran eggs (Loiácono and Margaría, 2002).
