The type specimens of Apoidea (Hymenoptera) deposited in the entomological collection of Instituto Oswaldo Cruz, Rio de Janeiro, RJ, Brazil

A list of 41 Apoidea (Hymenoptera) type specimens deposited in the Entomological Collection of the Instituto Oswaldo Cruz, Rio de Janeiro, RJ, Brazil is presented. The types previously belonged to the Zikan and Schrottky private collections. A total of 11 holotypes and 30 paratypes are listed with their respective data and literature.

Larval and pupal periods of Peckia chrysostoma and Adiscochaeta ingens (Diptera: Sarcophagidae) reared under laboratory conditions

Peckia chrysostoma obtained mean viability of 97.0ñ2.4 por cento for larvae and of 96.9ñ2.5 por cento for pupae (total viability of 94.0ñ3.7 por cento). Adiscochaeta ingens obtained mean viability of 93.0ñ7.5 por cento for larvae and of 92.8ñ7.6 por cento for pupae (total viability of 86.0ñ7.3 por cento). P. chrysostoma obtained mean larval period of 185ñ4 hr at 18§C, of 94ñ2 hr at 27§C and of 88ñ2 hr at room temperature (range of 23§C and 29§C). A. ingens obtained mean larval period of 169ñ1 hr at 18§C, of 77ñ1 hr at 27§C and of 84ñ2hr at room temperature. P. chrysostoma obtained mean pupal period of 23.5ñ1.3 days at 18§C, of 12.5ñ0.7 days at 27§C and of 15.5ñ0.7 days at room temperature. A. ingens obtained mean pupal period of 33.0ñ2.2 days at 18§C, of 16.0ñ1.0 days at 27§C and of 19.0ñ1.0 days at room temperature.

Longevity of adults of Peckia chrysostoma and Adiscochaeta ingens (Diptera: Sarcophagidae) reared with and without protein

With access to a proteic source in the diet the mean longevity and lethal time (MLT) of Peckia chrysostoma was 52.6 ñ 5.5 and 30.3 ñ 5.9 days, respectively. With an isolated protein source, the mean longevity was 49.1 ñ 2.6 days and the MLT was 28.5 ñ 0.8 days. Without a proteic source the mean longevity and the MLT lowered to 37.4 ñ 4.0 and 18.1 ñ 1.3 days, respectively. For Adiscochaeta ingens the mean longevity with access to a proteic source in the diet was 29.0 ñ 6.0 days and the MLT was 16.7 ñ 2.7 days. The figures with an isolated proteic source were 26.9 ñ 4.8 and 14.9 ñ 2.0 days, and without a proteic source were 24.7 ñ 4.2 and 13.3 ñ 1.4 days, respectively. These results show that in P. chrysostoma the longevity is higher than in A. ingens and that the access to the proteic source increase the longevity in both species.

Interespecific competition between Peckia chrysostoma and Adiscochaeta ingens (Diptera: Sarcophagidae) larvae reared in laboratory

Groups of 10 and 20 first instar larvae of Peckia chrysostoma (Wiedemann, 1830) were combined in a proteic source media with groups of the same number of first instar larvae of Adiscochaeta ingens (Walker, 1849) under the environmental conditions of Rio de Janeiro, RJ, Brasil. P. chrysostoma and A. ingens obtained average competitive potentials of 94.0 ñ 2.0% and 31.0 ñ 5.0% respectively. In the second experiment, larvae of P. chrysostoma were introduced approximately 15 hr after the introduction of A. ingens larvae (whose majority had already passed to the second instar) in the media. The corresponding average competitive potential of P. chrysostoma (82.0 ñ 2.0%) was decreased when compared to the first experiment, but still greater than that of A. ingens (64.5 ñ 9.5%). The competitive potential of A. ingens, however, increased significatively, demonstrating the influence of its previous colonization in the media for achieving a higher viability. In both experiments the competitive potential of P. chrysostoma was greater and similar to observations cited in the literature. Control-groups of each species were observed, individually, for the comparison. The mean value obtained for P. chrysostoma was 94.0 ñ 3.7% (0.0% [experiment 1] and only 12.8% [experiment 2] greater than the average competitive factor). For A. ingens the average was 86.0 ñ 7.3% (64.0% [experiment 1] and 25.0% [experiment 2] greater than average competitive factor)

Comparison of the reproductive behavior between isolated Peckia chrysostoma (Wiedemann, 1830) and Adiscochaeta ingens (Walker, 1849) (Diptera: Sarcophagidae) females reared in laboratory

In both species, maintained under laboratory environmental conditions, anautogeny was comproved and all females that had free access to proteic source were fertiles. We obtained the following average values for Peckiachrysostoma: 59.7 ñ 15.6 and 81.8 ñ 15.4 days of longevity in the respective cases of free access and no access to proteic source, 21.4 ñ 4.3 days of pre-larviposition period and 35.2 ñ 16.5 days of larviposition period, 5.3 ñ 1.8 larvipositions female with 7.0 ñ 1.1 days of periodicity, 35.7 ñ 6.1 larvae per larviposition leading to a total number of 183.8 ñ 69.2 viable larvae per female and 94.8% ñ 5.3% of productivity. The mean number of ovarioles per female was 56.4 ñ 9.8, resulting in a reproductive potential of 63.3%. For Adiscochaeta ingens, the obtained average values were: 41.3 ñ 6.3 and 52 ñ 13.1 days of longevity in the respective cases of free access and no access to proteic source, 15.3 ñ 1.7 days of pre-larviposition period and 21.5 ñ 7.5 days of larviposition period, 3 ñ 0.7 larvipositions per female with 10.4 ñ 0.8 days of periodicity, 30.3 ñ 8.2 larvae per larviposition leading to a total number of 78.5 ñ 21.7 viable larvae per female and 90.1% ñ 16% of productivity. The mean number of ovarioles per female was 54.6 ñ 5.2, resulting in a reproductive potential of 55.5%. Within applied parameters, the values obtained for P. chrysostoma demonstrate its superior productivity in comparison with A. ingens
