The subterranean termite, Coptotermes havilandi Holmgren, is reported from a previously undocumented site located in Manzanillo, Colima, Mexico. This is the first record of that exotic species on the West Coast of North America. Termites were found inhabiting and damaging pine logs in a fiscal warehouse at Manzanillo harbor. Their proximity to the harbor, in addition to the lack of any other infestations in the surroundings, suggests that they were probably introduced as a result of maritime trade. New distribution records are also reported in Mexico City (Mexico) and the State of Pará (Brazil). This study shows that that species continues being introduced in many countries despite the efforts of harbor quarantines.

El termes subterráneo, Coptotermes havilandi Holmgren, se registra de un sitio previamente no documentado localizado en Manzanillo, Colima, México. Es el primer registro de esta especie exótica en la costa oeste de América del Norte. Esta especie fue encontrada dañando tablas nuevas de pino almacenadas en una bodega fiscal del puerto de Manzanillo. Su proximidad al puerto, así como la falta de infestaciones en los alrededores, sugiere que muy probablemente fue introducida por vía marítima. También se incluyen nuevos registros de distribución en la Ciudad de México, D.F. (México) y para el estado de Pará (Brasil). Este trabajo muestra que la especie continúa siendo introducida por el hombre a muchos países a pesar de las cuarentenas establecidas.

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 Zikán and Schrottky private collections. A total of 11 holotypes and 30 paratypes are listed with their respective data and literature

Peckia chrysostoma obtained mean viability of 97.0±2.4% for larvae and of 96.9±2.5% for pupae (total viability of 94.0±3.7%). Adiscochaeta ingens obtained mean viability of 93.0±7.5% for larvae and of 92.8±7.6% for pupae (total viability of 86.0±7.3%). P. chrysostoma obtained mean larval period of 185±4 hr at 18ºC, of 94±2 hr at 27ºC and of 88±2 hr at room temperature (range of 23ºC and 29ºC). A. ingens obtained mean larval period of 169±1 hr at 18ºC, of 77±1 hr at 27ºC and of 84±2hr at room temperature. P. chrysostoma obtained mean pupal period of 23.5±1.3 days at 18ºC, of 12.5±0.7 days at 27ºC and of 15.5±0.7 days at room temperature. A. ingens obtained mean pupal period of 33.0±2.2 days at 18ºC, of 16.0±1.0 days at 27ºC and of 19.0±1.0 days at room temperature.

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

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 ± 2.0% and 31.0 ± 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 ± 2.0%) was decreased when compared to the first experiment, but still greater than that of A. ingens (64.5 ± 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 ± 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 ± 7.3% (64.0% [experiment 1] and 25.0% [experiment 2] greater than average competitive factor).

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 ± 15.6 and 81.8 ± 15.4 days of longevity in the respective cases of free access and no access to proteic source, 21.4 ± 4.3 days of pre-larviposition period and 35.2 ± 16.5 days of larviposition period, 5.3 ± 1.8 larvipositions female with 7.0 ± 1.1 days of periodicity, 35.7 ± 6.1 larvae per larviposition leading to a total number of 183.8 ± 69.2 viable larvae per female and 94.8% ± 5.3% of productivity. The mean number of ovarioles per female was 56.4 ± 9.8, resulting in a reproductive potential of 63.3%. For Adiscochaeta ingens, the obtained average values were: 41.3 ± 6.3 and 52 ± 13.1 days of longevity in the respective cases of free access and no access to proteic source, 15.3 ± 1.7 days of pre-larviposition period and 21.5 ± 7.5 days of larviposition period, 3 ± 0.7 larvipositions per female with 10.4 ± 0.8 days of periodicity, 30.3 ± 8.2 larvae per larviposition leading to a total number of 78.5 ± 21.7 viable larvae per female and 90.1% ± 16% of productivity. The mean number of ovarioles per female was 54.6 ± 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
