ABSTRACT

Abstract It is recorded for the first time in the state of Rio Grande do Sul the occurrence of Scobina melanocephala (Lepeletier, 1823), Scobina thoracica (Jorgensen, 1913) and Scobina poeciloides (Ashmead, 1895), being this last the first record for Brazil. Scobina melanopyga (Klug, 1834) and Scobina torquata (Konow, 1903) were also found in the study. The analyzed material was collected utilizing Malaise traps in tobacco (Nicotiana tabacum L.) fields and is deposited at the Entomological Collection of Santa Cruz do Sul.

ABSTRACT

Phymastichus coffea LaSalle is an African endoparasitoid of adults of the coffee berry borer, Hypothenemus hampei (Ferrari) that was introduced into Mexico for biological control purposes. The objective of this study was to investigate the oviposition behavior of P. coffea on its host under laboratory conditions. The results indicate that P. coffea females exhibited 12 behavioral acts during and after oviposition, such as, walking, cleaning, flying, surface landing, resting, host landing, host antennation, touching the host with forelegs, host recognition, walking on the host, oviposition and cleaning after oviposition. The sequence of each behavior is described in an ethogram.

ABSTRACT

Four species of Hymenoptera: Tanaostigmodes ringueleti (Brèthes, 1924), T. mecanga sp.nov. (Chalcidoidea, Tanaostigmatidae), Allorhogas taua sp. nov. (Braconidae, Doryctinae) and Eurytoma sp. (Chalcidoidea, Eurytomidae) were reared from two different types of galls of Calliandra brevipes Benth. (Fabaceae, Mimosoidea) in Juiz-de-Fora, Minas Gerais State, Brazil. The two Tanaostigmatidae species are probably the gall inducers; the Braconidae species probably is phytophagous inquiline in round gall type. The two new species are described and illustrated, including their immature stages.


Quatro espécies de Hymenoptera: Tanaostigmodes ringueleti (Brèthes, 1924), T. mecanga sp. nov. (Chalcidoidea, Tanaostigmatidae), Allorhogas taua sp. nov. (Braconidae, Doryctinae) e Eurytoma sp. foram obtidas de dois diferentes tipos de galhas de Calliandra brevipes Benth. (Fabaceae, Mimosoidea) em Juiz-de-Fora, MG, Brasil. As duas espécies de Tanaostigmatidae são os prováveis indutores das galhas; a espécie de Braconidae, provavelmente é um inquilino fitófago das galhas globosas. Estas duas novas espécies são descritas e ilustradas, incluindo os seus estágios imaturos.

ABSTRACT

The parasitoid Spalangia endius Walker is an efficient controller of Dipteran pupae, such as Musca domestica L. The entomopathogenic fungus Beauveria bassiana (Bals.) Vuil. is a regulator of insect populations, including these synanthropic pests. The aim of this work was to explore the possibilities of utilizing both agents in a combined form for the biocontrol of the domestic fly. Recently formed M. domestica pupae were inoculated by immersion in conidia suspension (10(8) conidia/ml) with two strains of B. bassiana (Bb6 and Bb10). The inoculated pupae were offered to the female parasitoid. In one bioassay they were offered pupae inoculated a single day and in other, pupae inoculated the following day as well. In both bioassays non inoculated (control) pupae were offered to the parasitoids until their death. Thirty females of S. endius were used for each strain and bioassay. From the study of the parasitoid offspring, life tables were built and the reproduction net rate (R0) and intrinsic natural increase (r m) were obtained among other demographic parameters; the parasitism percentages and sex ratios were also analyzed. B. bassiana did not affect significantly the biodemography of the parasitoid when pupae were inoculated a single time. On the other hand the R0 and the rm were smaller than that of the control without the fungus when pupae were inoculated twice, although sporulation was not observed in the cadavers of S. endius.


El parasitoide Spalangia endius Walker es un reconocido controlador de pupas de dípteros, tal como la Musca domestica L. El hongo entomopatógeno Beauveria bassiana (Bals.) Vuil. es un regulador de poblaciones de insectos, incluidas estas plagas sinantrópicas. El objetivo del trabajo fue explorar las posibilidades de utilización conjunta de ambos agentes para el control de la mosca. Se trataron pupas recién formadas de esta plaga con una suspensión de conidios (10(8) conidios/ml). Pupas inoculadas con dos cepas (Bb6 y Bb10) del hongo fueron ofrecidas a los parasitoides hembra. En un ensayo se les ofreció pupas inoculadas el primer día y en otro, inoculadas también al día siguiente; en los dos ensayos se les colocaron pupas normales hasta la muerte del parasitoide. Se usaron 30 hembras de S. endius para cada cepa y ensayo. A través del estudio de la progenie del parasitoide se construyeron tablas de vida, obteniéndose las tasas netas de reproducción (R0) e intrínsecas de incremento natural (r m) entre otros parámetros demográficos, así como el porcentaje de parasitoidismo y la proporción de sexos. B. bassiana no afectó significativamente la biodemografía del parasitoide cuando se lo expuso una sola vez, en cambio la R0 y la rm fueron más bajas que en el testigo sin el hongo cuando fueron expuestos dos veces, aunque no se observó esporulación en los cadáveres de S. endius.

ABSTRACT

Se realizaron investigaciones para determinar la presencia de especies de avispitas del género Trichogramma en el Estado Lara, Venezuela. En el campo, se colectaron huevos de lepidópteros en varios cultivos los cuales fueron llevados al laboratorio y observados diariamente hasta la emergencia de los adultos de Trichogramma. Las especies de Trichogramma también fueron obtenidas utilizando trampas con huevos de Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) y Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). En el laboratorio, especimenes machos de Trichogramma fueron montados en láminas microscópicas para mostrar la genitalia y otros caracteres morfológicos usados para su identificación. Los resultados mostraron que Trichogramma atopovirilia Oatman y Platner emergió de huevos de S. frugiperda colectados en plantas de maíz en La Palomera, Humocaro Alto y en El Parchal, Humocaro Bajo, Municipio Morán. T. atopovirilia también emergió de huevos de S. frugiperda colectados en plantas de maíz en Sabana Grande y en huevos de S. cerealella usados como trampas en plantas de pimentón en Tintinal, Municipio Andrés Eloy Blanco. T. exiguum Pinto y Platner emergió de huevos de S. frugiperda usados como trampas o colectados en plantas de maíz en Totumito y en La Palomera, Humocaro Alto. T. pretiosum Riley emergió de huevos de Phthorimaea operculella Zeller colectados en papa almacenada en Monte Carmelo, Sanare. La identificación de las especies de Trichogramma del Estado Lara permitirá su incorporación en futuros programas de control biológico de insectos plaga del orden Lepidoptera.


This work was conducted to determine the occurrence of Trichogramma wasp species in Lara State, Venezuela. Lepidopteran egg samples collected from various crop leaves were observed daily under laboratory conditions for emergence of Trichogramma species adult wasps. Trichogramma were also obtained from traps containing eggs from the hosts Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). In the laboratory, specimens of Trichogramma species were mounted on microscope slides to show male genitalia and other morphological characters used for its identification. Trichogramma atopovirilia Oatman y Platner emerged from S. frugiperda eggs collected in a cornfield at La Palomera, Humocaro Alto and at El Parchal, Humocaro Bajo, Municipio Morán. T. atopovirilia also emerged from S. frugiperda eggs collected in a cornfield at Sabana Grande and from S. cerealella eggs used as traps in a pepper culture at Tintinal, Municipio Andrés Eloy Blanco. T. exiguum Pinto y Platner emerged from S. frugiperda eggs used as traps or collected in cornfield at Totumito and at La Palomera, Humocaro Alto. T. pretiosum Riley emerged from Phthorimaea operculella Zeller eggs collected on stored potatoes at Monte Carmelo, Sanare. The identification of Trichogramma species in Lara State would be useful in the development of biological control programs for lepidopteran pests.
