| It was conducted a research, in urban areas, on the nesting habits and reproductive period of Pachycondyla striata, a species of ant that stings painfully. The study was motivated by the frequent reports of accidents in the city of São Paulo. The reports are more common during the reproductive seasons of the species, when the winged females sting the population, since they enter the houses of the people attracted to light. Although anaphylaxis for P. striata has not been reported yet, other close species may cause anaphylaxis, which makes important to understand their biology in order to take management and control measures. Fourteen green areas in the city of São Paulo, Brazil, were monitored in the search for the species and their nests that were found... |

| ABSTRACT Monodelphis glirina is endemic to the Amazon and its life habits and natural history are poorly known. Data on the species were collected in northern Mato Grosso, Brazil, including observations on its behavior and simpatry with congeners. During 10 expeditions and with an effort of 3,680 buckets-day, 29 M. glirina, three M. saci and one M. emiliae individuals were captured. Adults accounted for 82.8% of M. glirina captures, with a sex ratio of three males for each female. Capture of young and lactating females was seasonal, as both were captured only in the rainy season. We observed three events of M. glirina preying on rodents in pitfall traps, all with the same feeding behavior. We also report an individual climbing a tree at night, including a... |

| Eleonoria gen. nov. (type species: E. mesembria spec. nov. from Malaysia; five additional species from Japan, China (including Taiwan), Philippines, and Indonesia (Halmahera) are included), Orgilonia pasohensis spec. nov. from Malaysia, Orgilus reclinatus spec. nov. from Congo, O. alboannulatus spec. nov., and O. brevicaudatus spec. nov., both from Uganda, are described and partly illustrated. Keys to the species of Eleonoria gen. nov. and the genus Orgilonia van Achterberg are included. Eleonoria chuchiensis (Chou, 1995) is a new combination. The tribe Mesoscoelini Viereck, 1918 (= Aneurobraconinae Fahringer, 1936) is removed from the subfamily Agathidinae and included in the Orgilinae and synonymised with the tribe Mimagathidini (syn. nov.). |

| Lanceleaf crotalaria, Crotalaria lanceolata E. Mey (Leguminosae) was found hosting the small green stink bug, Piezodorus guildinii (Westwood), in Paraná State, Brazil. In the laboratory, nymphs showed less mortality when fed on immature pods of crotalaria (64%) than when fed on immature pods of soybean, Glycine max (L.) Merrill (88%). From 2nd stadium to adult, nymphs required less time to complete development on crotalaria (mean of females and males = 18.4 days) than on soybean (21.5 days). Fresh body weight at adult emergence was greater on crotalaria (mean of females and males = 51.4 mg) than on soybean (42.2 mg). Adult P. guildinii tended to live longer on crotalaria than on soybean. Mean adult longevity was 34.6 days on crotalaria, and 28.8 days on... |

| The biology of nymphs and adults of the neotropical pentatomid, Dichelops melacanthus (Dallas), feeding on the natural foods, soybean, Glycine max (L.) Merrill immature pods, and corn, Zea mays L. immature seeds, and on an artificial dry diet, was studied in the laboratory. Nymph developmental time was shorter on the natural foods (ca. 21-22 days) than on the artificial diet (28 days), and most nymphs reached adulthood on the food plants (55% on soybean and 73% on corn) than on the artificial diet (40%). Fresh body weight at adult emergence was similar and higher for females raised as nymphs on the natural foods, compared to females from nymphs raised on the artificial diet; for males, weights were similar on all foods. Mean (female and male) survivorship... |

| The southern green stink bug, Nezara viridula (L.), has several genetically determined types, three being the most common in Brazil: G (f. smaragdula - green body), O (f. torquata - green body with lateral and median lobes of the head and anterior margin of the pronotum yellow), and Y (f. aurantiaca - gold or orange body). Nymphal and adult performance of these types was studied at 15ºC/10hL, 22ºC/12hL, and 29ºC/14hL. Mean total nymph mortality in all types at 15ºC/10hL was high (ca. 80%), especially for type G (98%); at 22ºC/12hL, the greatest mortality (55%) occurred in type G, and at 29ºC/14hL in type Y (65%). In general, at combinations of higher temperatures and longer photoperiods, nymphs developed faster. Adult longevity of type G decreased from ca.... |

| During a 3 week study, a total of 55 individuals of the redlip blenny (Ophioblennius atlanticus) were observed for at least two 15-minute periods, and several for ten of such periods. The sizes of their territories were estimated, the color pattern of each specimen an intra and interspecific interactions were recorded. The mean territory size of the redlip blenny in the study area appeared to be greater than that of these blennies studied in Curacao and Barbados by NURSALL (1977), the difference reflecting perhaps different methods of identifying the territories or a lower density of O. atlanticus in the Santa Marta área. Territories did not appear to be as consistently defended at the study area as at Barbados/Curacao and our impression ¡s that... |

| Observations on living estuarine nematodes show that previous feeding type classifications do not accurately represent the trophic structure of an intertidal mudflat in the Westerschelde Estuary (Netherlands). A new scheme with six major nematode feeding guilds is proposed: (1) microvores; (2) ciliate feeders; and (3) deposit feeders sensu stricto are all nematodes without a distinct buccal armature. In the first two groups bacteria and protozoa, respectively are the major particulate food sources, while other items are included in the diet of the third. The three other categories are recognized among the nematodes with a buccal armature: (4) epigrowth feeders; (5) facultative predators; and (6) predators. Diatoms and other microalgae are an important... |

| Clitoria fairchildiana (Howard) is a tree largely distributed in Brazil, used for urban arborization. In April 2001, the psyllid Euphalerus clitoriae Burckhardt & Guajará was reported on this plant in the metropolitan areas of Recife, PE, Brazil. This report records the occurrence of E. clitoriae and studies some of its biological aspects in this area. With this purpose, C. fairchildiana leaves were sampled weekly, and E. clitoriae nymphs as well as Aprostocetus sp. larvae and nymphs were collected and counted. The E. clitoriae population ranged from 2 to 90 nymphs per leaflet. The Aprostocetus sp. percentage of parasitism ranged from 3 to 24%. The frequency curve for pygidium width ranged from 120 to 140; 200 to 240; 300 to 380; 460 to 580, and... |

| Three species of oysters have been or are cultivated in Europe: Crassostrea angulata, C. gigas, and Ostrea edulis. If we follow the taxonomic critera of Grassé, the European oysters belong to the group of Mollusca, class of Lamellibranchia or Bivalves, order of Filibranchia, family Ostreidae with two genera: C. angulata (Lamarck), Portuguese, cupped oyster; C. gigas, (Thunberg), Japanese or Pacific, cupped oyster; Ostrea edulis (Linné), fiat European oyster. Some authors think that C. gigas and C. angulata belong to the same species. lndeed, Ranson stated that the characteristics of the larvae are the same, and Menzel obtained viable hybrids (F2) between these two oysters. AIso, Buroker et al. in studying the genetic variations of proteins and enzymes of... |

| Originating from the north eastern Asia, Crassostrea gigas is endemic to Japan, but has been introduced and translocated, mainly for aquaculture purpose, into several countries, almost worldwide (1). In North America, the species can be found from Southeast Alaska to Baja California, while in European waters the species is cultured from Norway to Portugal as well as in Mediterranean Sea (Fig.1) (2). Biological characteristics make it suitable for a wide range of environmental conditions, although it is usually found in coastal and estuarine areas within its natural range. Although highly variable, the invasiveness pattern of C. gigas has been demonstrated in several countries and therefore considered as a pest or a noxious species in those areas (3). |

| The principal objective of the work carried out in the deep waters adjoining the island shelf around Martinique between July 1991 and april 1992 was to establish an initial inventory of potentially exploitable deep benthic resources.The cylindrical lobster pot used during fishing experiments allowed the catch of a varied carcinological marine organisms of which six species at least have economic interest : 5 species of shrimp all belonging to the sub-order of Caridea of the Pandalidae family : Plesionika edwardsi, P. (macropoda) polyacanthomerus, P.laevis, Heterocarpus ensifer and H.laevigatus, and one species of prawn of the Nephropidae family : Eunephrops cadenasi. The yields, compared to those of commercial fishermen, were medium or good for Plesionika... |
