SYSTEMATICS AND BIOLOGY OF THE CROP ASSOCIATED SPECIES OF POLYNEMA (HYMENOPTERA: MYMARIDAE) IN SOUTHERN ARIZONA (PARASITOIDS, PARASITE, ALFALFA HOPPERS, LEAFHOPPERS).

LAKIN, KENNETH RYAN. January 1985 (has links)
Egg parasitoid wasps of the genus Polynema (Hymenoptera: Mymaridae) were collected over a 4-year period from crop-associated areas in southern Arizona. Seven morphologically distinct species were collected with 3 species identified. Evidence was found for the existence of an additional sibling species. Taxonomic characters currently used for this genus were evaluated for stability when the parasitoids develop in alternate hosts and some were found to be unreliable. A key to the Polynema species from Arizona were composed utilizing new characters. Biological studies were carried out on 5 of these species to determine host species, longevity, developmental time, and potential fecundity. Three of these species exhibit the potential for sympatric parasitization of the eggs of the threecornered alfalfa hopper. A 2-year study of the seasonal distribution of these parasitoids in alfalfa fields in southern Arizona was carried out.

Diferenciação etológica e morfofisiológica das castas de Mischocyttarus (Monogynoecus) montei, Zikán, 1949 (Hymenoptera, vespidae, mischocyttarini), com especial referência à regulação social das colônias

A biologia e a organização social das vespas eussociais primitivas, em especial o gênero Mischocyttarus, são pouco conhecidas, apesar da grande diversidade de espécies desse gênero nos trópicos. Com o objetivo de identificar os mecanismos envolvidos na regulação social de Mischocyttarus (M.) montei, foram coletadas 9 colônias para a análise da morfofisiologia dos indivíduos, sendo que destas, 6 foram previamente observadas em condições naturais no Campus da Unesp de Rio Claro, SP. Foi verificado que a dinâmica hierárquica desta espécie é regulada através de três estratégias principais: a) interações agonísticas moderadas entre os indivíduos de maneira a permitir que fundadoras se associem, estabelecendo uma hierarquia de dominância mas ao mesmo tempo garantindo a viabilidade da colônia no início do ciclo; b) alimentação e gasto energético diferencial dos adultos, onde os mais dominantes ingerem maiores quantidades de alimento, em especial fontes de proteína, ao mesmo tempo em que realizam tarefas de baixo custo energético e comportamentos relacionados à dominância; e c) utilização da oofagia diferencial como forma indireta de competição e monopolização da postura de ovos. Através desses mecanismos, a hierarquia é regulada de forma dinâmica, de maneira a permitir que 2 qualquer indivíduo possa ocupar diferentes papéis dentro da colônia, uma vez que, como verificado, os adultos emergem com capacidades reprodutivas similares e não apresentam diferenças morfológicas significativas entre as castas. A determinação de suas funções na colônia dependerá, portanto, das estratégias acima descritas. / The wasps, due to their monophyletic characteristics, are an excellent model to explain the evolutionary scenario of the social behavior in the Hymenoptera. The biology and social organization of primitively eusocial wasps, especially of Mischocyttarus genera, are relatively poor studied, despite of its marked diversity in Neotropical regions. With the aim of identify the traits involved in social regulation of M. (Monogynoecus) montei nine colonies were collected and used in morphological and physiological analysis, from these six were monitored in natural conditions at UNESP, in Rio Claro, SP. The results showed that the hierarchical dynamics of this specie is regulated based on three main strategies: a) moderated agonistics interactions among nestmates, which leads to foundress associations foundations and assure the establishment of a dominance hierarchy and the success of the colony in initial phases of development; b) different feeding and energetic cost tasking of adults, whereas the dominant females feed on higher quantities of food, especially protein, and perform tasks with low energetic cost, mainly those related to dominance; and c) differential oophagy as an indirect strategy of competition, avoiding the subordinate oviposition. Through these mechanisms the hierarchy is regulated in a dynamical way, in which any female can assume different tasks in the colony, once the adults emerge with similar reproductive potential and a marked morphological caste differentiation is absent. The role of each nestmate, therefore, will depend on the strategies previously described.
