Abstract: development and viability of the egg parasitoids telenomus podisi ashmead and trissolcus brochymenae (ashmead) (hymenoptera: scelionidae) were studied at five constant temperatures ranging from 17°c to 32°c on its host, the predatory bug podisus nigrispinus (dallas) (heteroptera: pentatomidae). female development from egg to adult ranged from 10.8 days (32°c) to 48.6 days (17°c) for t. podisi, and from 10.2 days (32°c) to 35.4 days (17°c) for t. brochymenae. parasitism viability ranged from 89.0 to 92.7% for t. brochymenae. however, t. podisi viability decreased in lower and higher temperatures. lower threshold temperatures for egg to adult female development was estimated at 11.1°c for t. podisi and 9.5°c for t. brochymenae. thermal requirements for this period was 205.3 and 214.7 degree-days for t. podisi and t. brochymenae, respectively. number of generations per year of these parasitoids and its host, considering the temperature conditions of eucalyptus areas, were estimated to be 22.6, 23.9 and 10.2 for t. podisi, t. brochymenae and p. nigrispinus, respectively. these results indicate that t. brochymenae is better adapted to temperature variations than t. podisi, however, both species can successfully parasitize p. nigrispinus.

Abstract: pupae of thyrinteina arnobia (stoll) and thyrinteina leucoceraea rindge (lepidoptera: geometridae) were obtained from eucalyptus cloeziana f. muell and eucalyptus urophylla s.t. blake plants, respectively. specimens of a parasitoid emerged from t. arnobia pupae and also found parasitising t. leucoceraea pupae in the field were identified as palmistichus elaeisis delvare and lasalle (hymenoptera: eulophidae). this is the first report on p. elaeisis parasitizing t. arnobia and t. leucoceraea pupae in natural conditions in brazil. p. elaeisis also parasitized these hosts and bombyx mori linnaeus (lepidoptera: bombycidae), anticarsia gemmatalis hubner, pseudaletia sequax franclemont, alabama argillacea huebner (lepidoptera: noctuidae), dirphia moderata bouvier (lepidoptera: saturniidae) and halysidota pearsoni watson (lepidoptera: arctiidae) in the laboratory. the production and release of p. elaeisis could be an efficient alternative for controlling lepidoptera defoliators in eucalyptus plantations.

Abstract: Lepidoptera species were monitored in a plantation of Eucalyptus grandis in the Municipality of Bom Despacho, State of Minas Gerais, Brazil from March 1987 to February 1992. A total of 547 species were collected and divided in: primary pests: 13; secondary pests: 20; species without defined importance to eucalyptus: 79; and non-identified species: 435. These four groups had a mean of 5231.29; 338.18; 438.16 and 2222.87 individuals with a total of 8229.87 individuals collected per trap. The number of species without defined importance to eucalyptus, and non-identified species, increased during the collecting period of five years while those of primary and secondary pests showed similar numbers in all years. The most collected primary pests Thyrinteina arnobia Stoll and Stenalcidia sp. (Geometridae) showed higher frequencies during the driest and coldest periods of the year, whereas Psorocampa denticulata Schaus (Notodontidae) was most frequent during periods of higher rainfall. Species of groups III and IV increased in diversity with eucalyptus age. This area has a high probability of outbreaks of eucalyptus defoliating caterpillars, especially T. arnobia. For this reason, lepidopteran pests should be monitored in this plantation during the driest and coldest periods of the year, when they can reach population peaks. Rev. Biol. Trop. 54(2): 553-560. Epub 2006 Jun 01. De marzo de 1987 a febrero de 1992 se realizó un monitoreo con trampas luminosas en plantaciones de Eucalyptus grandis en Bom Despacho, Minas Gerais, Brasil. Se recolectaron 547 especies del orden Lepidoptera: plagas primarias: 13; plagas secundarias: 20; especies sin importancia definida para el cultivo de eucalipto: 79; y especies no identificadas: 435. Estos cuatro grupos tuvieron medias de 5231.29; 338,18; 438.16 y 2222.87 individuos por trampa respectivamente, para un total de 8229.87 lepidopteros recolectados por trampa. Durante los cinco a os hubo un aumento del número de especies de los grupos III y IV. Las plagas primarias con mayor número de individuos fueron Thyrinteina arnobia Stoll y Stenalcidia sp. (Geometridae), con las mayores frecuencias para los meses más secos y fríos del a o. Psorocampa denticulata Schaus (Notodontidae) fue más abundante en los periodos más lluviosos. La probabilidad de brotes de larvas desfoliadoras de eucalipto, principalmente T. arnobia, es alta en la región. Se recomienda hacer el monitoreo de lepidópteros plaga en los periodos más secos y fríos del a o, cuando pueden presentar picos poblacionales.

Abstract: palmistichus elaeisis delvare and lasalle (hymenoptera: eulophidae) is a gregarious and polyphagous parasitoid mainly of lepidoptera pupae. the objective of this paper as to study the developent of parasitoid on bombyx mori l. (lepidoptera: bombycidae) pupae exposed to one, nine, 18, 27, 36, 45 or 54 female p. elaeisis, respectively. the females of the parasitoid remained in contact with pupae for 24 hours in glass tubes (14.0 x 2.2 cm), packed in a climatic chamber regulated at 25 ± 2°c, 70 ± 10% relative humidity and photo phase of 12 hours. with the exception of density 1:1 (72.72%), in other densities parasitism was 100%. adults of p. elaeisis did not emerge from pupae at densities of 1:1 and 9:1, but 100.0% of parasitoid emergence was observed at the density of 45:1 and 54.54% at 54:1. the duration of the life cycle of this parasitoid ranged from 20 to 28 days. p. elaeisis produced 49 to 589 descendants per pupa of b. mori. the sex ratio of p. elaeisis ranged from 0.93 ± 0.01 to 0.97 ± 0.01 without differences with 18, 27, 36, 45 and 54 females/host. this parasitoid should be reared with the density of 45 females per pupa of b. mori.

Anais da Sociedade Entomológica do Brasil , 1998, DOI: 10.1590/S0301-80591998000100010
Abstract: the effect of feeding intervals on podisus nigrispinus (dallas) (heteroptera: pentatomidae) females was studied. females were fed during 24 hours after either one, two, four, eight or 16 days with musca domestica l. (diptera: muscidae) larvae at 24 ± 3o c, 70 ± 10% rh and photophase of 12 hours. females of p. nigrispinus fed every one, two and four days produced higher number of eggs (225.4, 184.6 and 135.3 eggs, respectively) than those fed every eight or 16 days (8.3 and 0.0 eggs, respectively). females fed every four days lived longer (43.0 days) than those fed every eight or 16 days (27.3 and 10.6 days).

Abstract: trichogramma is among the most important genus of biological control. this research evaluated the parasitism potential of trichogramma maxacalii on eggs of oxydia vesulia at different embryonic developmental stages. twenty five eggs of o. vesulia one, three, five and seven days old were offered to the parasitoid in a fifteen replication essay, for a period of 24 hours. parasitism rate, viability, sexual rate and females that parasited were not influenced by the age of o. vesulia eggs. low parasitism rate of t. maxacalii in eggs of o. vesulia was found but more than 70% of the females of this parasitoid showed parasitism on eggs up to five days old.

Abstract: lepidoptera defoliators are important pests of eucalyptus. this research aimed to evaluate the potential of trichogramma acacioi and trichogramma pretiosum (hymenoptera: trichogrammatidae) to control the eucalyptus defoliator oxydia vesulia (lepidoptera: geometridae). biological parameters and parasitism rate of trichogramma on eggs of o. vesulia were evaluated under laboratory conditions. trichogramma pretiosum did not parasitized eggs of o. vesulia but more than 93% of t. acacioi females parasitized eggs of this defoliator, showing its potential for the biological control of this lepidoptera.
