O gênero Anthidium Fabricius na América do Sul: chave para as espécies, notas descritivas e de distribuição geográfica (Hymenoptera, Megachilidae, Anthidiini)

The genus Anthidium Fabricius in the South America: key for the species, descriptive notes, and geographical distribution (Hymenoptera, Megachilidae, Anthidiini). The Anthidiini, in South America, is represented by a single genus Anthidium Fabricius, 1804 (type-species: Apis manicata Linnaeus, 1758). Thirty nine species are treated in this paper, as follows: Anthidium alsinai Urban, 2001; A. andinum Joergensen, 1912; A. anurospilum Moure, 1957 nom. reval. (formerly = A. espinosai Ruiz, 1938); A. atricaudum Cockerell, 1926; A. aymara Toro & Rodríguez, 1998; A. chilense Spinola, 1851; A. chubuti Cockerell, 1910; A. colliguayanum Toro & Rojas, 1970; A. cuzcoense Schrottky, 1910; A. danieli Urban, 2001; A. decaspilum Moure, 1957; A. deceptum Smith, 1879; A. edwini Ruiz, 1935; A. espinosai Ruiz, 1938; A. falsificum Moure, 1957; A. friesei Cockerell, 1911; A. funereum Schletterer, 1890; A. garleppi Schrottky, 1910 = A. matucanense Cockerell, 1914 syn. nov.; A. gayi Spinola, 1851; A. igori Urban, 2001; A. larocai Urban, 1997; A. latum Schrottky, 1902; A. luizae Urban, 2001; A. manicatum (Linnaeus, 1758); A. masunariae Urban, 2001; A. nigerrimum Schrottky, 1910; A. paitense Cockerell, 1926; A. penai Moure, 1957; A. peruvianum Schrottky, 1910; A. rafaeli Urban, 2001; A. rozeni Urban, 2001; A. rubripes Friese, 1908 = A. boliviense Friese, 1920 syn. nov. = A. adriani Ruiz, 1935 syn. nov. = A. kuscheli Moure, 1957 syn. nov.; A. sanguinicaudum Schwarz, 1933; A. sertanicola Moure & Urban, 1964; A. tarsoi Urban, 2001; A. toro Urban. 2001; A. vigintiduopunctatum Friese, 1904; A. vigintipunctatum Friese, 1908, and A. weyrauchi Schwarz, 1943. Some taxonomic comments are made for each species, and new data on geographic distribution are also given. The females of A. andinum, A. igori, A. rozeni and the male of A. anurospilum are described for the first time. Identification keys (for males and females), as well as illustrations for almost all species, are provided.

Uma espécie nova de Xylocopa Latreille, 1802, e notas sobre Xylocopa transitoria Pérez e X. mordax Smith (Hymenoptera, Apoidea)

A new species of Xylocopa Latreille, 1802, and notes on Xylocopa transitoria Pérez and X. mordax Smith (Hymenoptera, Apoidea). Xylocopa (Neoxylocopa) orthogonaspis sp. nov. (Brazil, Amazonas) is described. It is a remarkable species from the Amazonian Region easily recognized by the strong and sharp right angle between upper and posterior portions of the scutellum; the wings are slightly brown with a brassy hue and a little vinaceous apex. Some notes to separate Xylocopa (N.) orthogonaspis sp. nov. from X. (N.) transitoria Pérez, 1901, and X. (N.) mordax Smith, 1874, are given. Xylocopa (N.) submordax Cockerell, 1935, on the other hand, is considered as a new synonym of X. (N.) transitoria Pérez, 1901.

Comportamento de parasitismo de Trichogramma atopovirilia Oatman & Platner e Trichogramma pretiosum Riley (Hymenoptera, Trichogrammatidae) em posturas de Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae)

The parasitism behavior of Trichogramma atopovirilia and T. pretiosum in Spodoptera frugiperda eggs was evaluated focusing on the features related to the associative learning (alpha conditioning) and recognition of the egg parasitized by the female after the first oviposition experience. Females of both species were observed to recognize the parasitized egg, which takes place after the female drills into the host egg. Following oviposition, 43.59% and 67.53 of females began to feed with an average feeding time of 73.26 ± 11.57 and 64.04 ± 7.05 seconds for T. atopovirilia and T. pretiosum, respectively. The time elapsed in each step of the parasitism behavior significantly decreased after the first oviposition experience, with a trend to stabilize after the 2nd or 3rd egg parasitized, indicating associative learning in these Trichogramma species.

Beyond Smith's rule: An optimal dynamic index, rule for single machine stochastic scheduling with convex holding costs

Most research on single machine scheduling has assumedthe linearity of job holding costs, which is arguablynot appropriate in some applications. This motivates ourstudy of a model for scheduling $n$ classes of stochasticjobs on a single machine, with the objective of minimizingthe total expected holding cost (discounted or undiscounted). We allow general holding cost rates that are separable,nondecreasing and convex on the number of jobs in eachclass. We formulate the problem as a linear program overa certain greedoid polytope, and establish that it issolved optimally by a dynamic (priority) index rule,whichextends the classical Smith's rule (1956) for the linearcase. Unlike Smith's indices, defined for each class, ournew indices are defined for each extended class, consistingof a class and a number of jobs in that class, and yieldan optimal dynamic index rule: work at each time on a jobwhose current extended class has larger index. We furthershow that the indices possess a decomposition property,as they are computed separately for each class, andinterpret them in economic terms as marginal expected cost rate reductions per unit of expected processing time.We establish the results by deploying a methodology recentlyintroduced by us [J. Niño-Mora (1999). "Restless bandits,partial conservation laws, and indexability. "Forthcomingin Advances in Applied Probability Vol. 33 No. 1, 2001],based on the satisfaction by performance measures of partialconservation laws (PCL) (which extend the generalizedconservation laws of Bertsimas and Niño-Mora (1996)):PCL provide a polyhedral framework for establishing theoptimality of index policies with special structure inscheduling problems under admissible objectives, which weapply to the model of concern.

Biologia e parasitismo de Trichogramma atopovirilia Oatman & Platner e Trichogramma pretiosum Riley (Hymenoptera, Trichogrammatidae) em ovos de Spodoptera frugiperda (J.E. Smith) (Lepidoptera, Noctuidae)

Comparou-se a capacidade de paratisimo e o desenvolvimento de Trichogramma atopovirilia Oatman & Platner e T. pretiosum Riley visando à seleção da espécie mais adequada para o controle de Spodoptera frugiperda (J. E. Smith). Os experimentos foram conduzidos em laboratório à temperatura de 25±2ºC, U.R. de 70±0% e fotoperíodo de 14L:10E. Tanto T. atopovirilia como T. pretiosum desenvolveram-se bem e mostraram-se adaptados a ovos de S. frugiperda, mesmo após serem criados por várias gerações em ovos de Anagasta kuehniella Zeller. Entretanto, fêmeas de T. atopovirilia foram mais agressivas e de maior especificidade à praga, já que apresentaram maior capacidade de parasitismo em posturas com diferentes barreiras físicas e maior aceitação pelo hospedeiro natural, em relação à A. kuehniella. Por este maior parasitismo e especificidade de T. atopovirilia aos ovos da praga, deve-se dar preferência à utilização desta espécie para controle de S. frugiperda.

Notas sobre o tipo de Trigona limao Smith (Hymenoptera, Apidae, Lestrimelitta)

O nome limao tem sido usado para espécies distintas do gênero Lestrimelitta. O material-tipo de Smith depositado no The Natural History Museum (Londres) foi examinado. A operária de L. limao é descrita e o lectótipo para Trigona limao Smith, 1863 é designado. Esta espécie encontra-se restrita aos cerrados da porção central do Brasil, de São Paulo ao Maranhão. Distingue-se de outras espécies pelos seguintes caracteres diagnósticos: vértice com pouquíssimas cerdas eretas, muito finas e curtas, restritas à região interocelar; bordo anterior do mesoscuto com cerdas eretas castanhas nas laterais; laterais do mesepisterno com cerdas eretas esparsas e restritas à porção ventral e curvatura entre porções lateral e ventral, tornando-se mais longas próximo à base da coxa média; contorno da abertura do espiráculo propodeal, aproximadamente 2,5 x mais longo do que largo; flancos do propódeo coberto por pilosidade decumbente esbranquiçada, fina e ramificada; esporão mesotibial muito reduzido; tergo metassomal 1 com cerdas enegrecidas nas porções laterais.
