“…In their larval phase they consume seeds from many plant families, although 84% of their host plants are Fabaceae (Bondar, 1936;Johnson, 1981;Johnson et al, 1995;Kingsolver, 2004). M. bicoloripes and Stator limbatus Horn were also obtained in other studies on the insects associated with fruits and seeds of E. contortisiliquum in Pernambuco, Brazil (Meiado et al, 2013). Meiado et al (2013) described a strict relationship between the number of holes in the fruits and the number of M. bicoloripes individuals, with seven as the maximum number of individuals feeding on E. contortisiliquum fruits.…”

“…The number of Cerambycidae (3 individuals/ 1.69%) was low compared to the results obtained by Meiado et al (2013). This family can be found in different habitats during development and most species are wood-borers (Marinoni et al, 2001).…”

This study aimed to inventory the herbivore insects associated with Enterolobium contortisiliquum (Vell.) Morong (Fabaceae) fruits and seeds and their primary and secondary parasitoids. Six samples collected between May and October 2013 yielded 210 fruits, from which 326 insects of six orders emerged: Coleoptera, Hymenoptera, Lepidoptera, Diptera, Thysanoptera and Psocoptera. Coleoptera (five families) was represented by the seed consumers Merobruchus bicoloripes Pic, Stator sp. Bridwell (Chrysomelidae, Bruchinae), two species of Silvanidae, one species of Scolytinae (Curculionidae), one species of Nitidulidae and one species of Cerambycidae. The cerambycid was also observed forming galleries on fruit mesocarp. Immature individuals of Lepidoptera were observed consuming the fruits and seeds. From the seven Hymenoptera families, only two species were associated with Coleoptera, being Horismenus Walker sp. (Eulophidae) as parasitoid of M. bicoloripes, and Neoheterospilus falcatus (Marsh) (Braconidae) as parasitoid of Scolytinae. The Lepidoptera parasitoids represented four genera: Pseudophanerotoma Zetel, Chelonus Panzer (Braconidae), Orgilus Nees (Braconidae) and Goniozus Forster (Bethylidae). The host associations for the reared parasitoids Bracon Fabricius (Braconidae), Pimplinae sp. (Ichneumonidae) and Perilampus Forster (Perilampidae) were not confirmed. We obtained a single representative of Diptera (Tachinidae) associated with Lepidoptera hosts in this food web.

rEsumo -O objetivo deste estudo foi avaliar a morfometria do fruto e as respostas germinativas de sementes de Handroanthus spongiosus (Rizzini) S. Grose (Bignoniaceae) submetidas a fatores ambientais, assim como contribuir para o conhecimento da ecofisiologia dessa espécie ameaçada de extinção. As sementes foram coletadas no município de Casa Nova, localizado Norte do Estado da Bahia. Foi determinada a temperatura ideal para germinação das sementes, além de avaliar o efeito da temperatura e dos estresses hídrico e salino na germinação das sementes. Também foram avaliados o peso, o comprimento e a quantidade de sementes em cada fruto da espécie. Foi observado que não há uma uniformidade no tamanho e na quantidade de sementes presente nos frutos. A temperatura ideal para a germinação das sementes foi 25°C e a espécie se mostrou tolerante a faixa de temperatura de 15 a 35°C. Observou-se, ainda, que H. spongiosus não se mostrou tolerante aos estresses hídrico e salino, o que pode estar relacionado à distribuição restrita da espécie em algumas regiões da Caatinga.

Grose (Bignoniaceae) seeds submitted to environmental factors, as well as to contribute to the knowledge of the ecophysiology of this species threatened with extinction. Seeds were collected in the municipality of Casa Nova, located north of the State of Bahia. It was determined the ideal temperature for seed germination, besides evaluating the effect of temperature and water and saline stress on seed germination. The weight, length and quantity of seeds in each fruit of the species were also evaluated. It was observed that there is no uniformity in the size and quantity of seeds present in the fruits. The ideal temperature for seed germination was 25°C and the species showed tolerance to a temperature range of 15 to 35°C. It was also observed that H. spongiosus was not tolerant to water and saline stress, which may be related to the restricted distribution of the species in some Caatinga regions. KEywords

“…Intensity of predispersal and post-dispersal infestation by several predators contributes significantly to seed mortality, affecting the distribution of several forest species (ZHANG et al, 1997;SANTOS et al, 2001). Some studies show that the fruits and/or seeds of a great number of economically or ecologically valuable native tree species are regularly damaged by different groups of insects (HULME & BORELLI, 1999;SANTOS et al, 2001;SARI et al, 2002;MEIADO et al, 2013), many of which are strikingly preyspecific (JANZEN, 1980). Predispersal predation by insects may cause mortality in up to 80% of the seeds produced in many grassland and forest habitats (ANDERSEN, 1988).…”

Predispersal infestation of Vochysia haenkeana seeds by Lius conicus

et al. 2017

The deficient development of fertile seeds of native forest plant species in Brazil limits the reproduction of these plants in various conditions. Among the limiting biotic factors in quality and quantity of the forest seeds, borer insects are quite prominent, before and after their dispersion. This study reports for the first time a host of the buprestid beetle Lius conicus (Gory & Laporte, 1840). The larval development of L. conicus takes place in the seed capsules of Vochysia haenkeana Mart. (Vochysiaceae), a typical tree species in the Brazilian cerrado biome. In two regions of the cerrado in Goiás State, Brazil, almost ripe fruits of V. haenkeana were collected directly from the plants. After natural drying, and fruit and seed processing in laboratory, damage caused by the L. conicus larvae was quantified and qualified. Bigger fruits were preferred as hosts. Fruits developing on the eastern side of the plant were most frequently occupied by L. conicus. Seed lots of bigger fruits showed damage up to 37.5% from the infestation by L. conicus larvae. There was only one larva per fruit, which damaged all the seeds of the capsule (three or four) and generally consumed around 26% of the seed dry mass.
