Asymmetric intraguild predation of Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) on a native Coccinellidae guild Rev. Bras. entomol.
Castro-Guedes,Camila Fediuk de; Almeida,Lúcia Massutti de; Moura,Mauricio Osvaldo.
Abstract Harmonia axyridis is an exotic species that can cause serious impacts on native biodiversity in areas where it is introduced to act as a biological control agent. This predator is often involved with intraguild predation, in most cases with aphids predators. Here, we report the results of experiments designed to understand the outcome of the invasion of H. axyridis on native coccinellid aphidophagous guilds using intraguild predation as a theoretical framework. Tests were conducted to determine the interactions between 1st and 4th instars larvae and H. axyridis adults, with Cycloneda sanguinea, Cycloneda pulchella, Eriopis connexa and Hippodamia convergens larvae, as well as eggs predation rate. Two treatments were used: absence and presence of...

Cladocers, Copepods and Rotifers in rice-fish culture handled with metsulfuron-methyl and azimsulfuron herbicides and carbofuran insecticide Ciência Rural
Golombieski,Jaqueline Ineu; Marchesan,Enio; Baumart,Joele Schmitt; Reimche,Geovane Boschmann; Resgalla Júnior,Charrid; Storck,Lindolfo; Santos,Sandro.
This study determined the effects of metsulfuron-methyl, azimsulfuron and carbofuran in communities: Cladocers, Copepods and Rotifers that are present in irrigated rice farming with the rice-fish system. The field experiment was conducted in the 2004/05 growing season with eight treatments. The fish species were: Cyprinus carpio, Ctenopharyngodon idella and Aristichthys nobilis, introduced seven days after treatments were applied. Water samples were collected 17 days before and 1st, 3rd, 10th, 18th, 31th, 51th, and 75th days after the agrochemicals were applied for identification and evaluation of the zooplankton. The results indicated that the herbicides did not affect the zooplankton community studied and carbofuran insecticide application provoked...

Development of Dichelops melacanthus and its egg parasitoid Telenomus podisi reared on Bt-soybean MON 87701 x MON 89788 and its near conventional isoline under different temperatures Anais da ABC (AABC)
Bortolotto,Orcial C.; Bueno,Adeney F.; Stopa,Ynaiara K.; Silva,Gabriela V.; Queiroz,Ana Paula.
Dichelops melacanthus was studied under controlled conditions (60 ± 10% RH and 14/10 h L/D photoperiod), and three constant temperatures (19, 25, and 31 ± 2 °C). Fresh pods of MON 87701 × MON 89788 soybeans and its near non-Bt isoline (A5547) were supplied to nymphs and adults. The biology of T. podisi was studied in the same controlled RH conditions, but only at the standard temperature of 25 ± 2 °C. Overall, the development of D. melacanthus was better at higher temperatures, which accelerated the development of the stink bug without affecting adult biological parameters. No influence of Bt-soybeans on the biology of the pest was observed in any temperature studied, which shows that D. melacanthus is not affected by this transgenic soybean. The egg...

Effects of a formulation of Bacillus thuringiensis on the parasitoid Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) under laboratory conditions. Repositório Alice
SA, L. A. N. de; CAPALBO, D. M. F.; NARDO, E. A. B. de; MAIA, A. H. N..
Assessing the potential environmental effects of biopesticides is an important part of its development and registration process. In Brazil little attention has been given to this approach, but now with the new approved rules for biopesticides registration that issue will be increasingly considered (COSAVE, 1997). Among the potential safety issues related to the use of microorganisms for pest control pathogenicity and toxicity effects on non-target beneficial organisms are the main concern (OECD, 1995; USEPA, 1989; Cook et al, 1996). In addition to that potential hazards there are those posed by microbial contaminants and by sybstances used in the formulation of biopesticides (e.g. stickers, carriers, spreaders, UV protectors) (Burges, 1981). Bacillus...

Phytophagous mites on genetically modified maize with Bacillus thuringiensis genes Ciência Rural
Ferreira,Tamara Esteves; Fadini,Marcos Antonio Matiello; Mendes,Simone Martins; Marinho,Cidália Gabriela Santos; Cruz,Ivan.
ABSTRACT: The study of non-target organisms such as mites, can provide information about the possible effects of transgenic maize cultivars on the arthropod community. This study aimed to evaluate the abundance of phytophagous mites in the area of Bt maize and evaluate the instantaneous population growth rate, and food preference of phytophagous mites on Bt maize. We registered the species occurrence and the number of adult mite individuals on four maize cultivars, one non-Bt 30F35, and three containing the proteins Cry1Ab (30F35 Yg), Cry1F (30F35 Hx) and Vip3a (Impacto Viptera). Cry proteins disrupt the midgut epithelium of insect pests. The food preference and instantaneous population growth rate (ri) were evaluated using the two-spotted spider mite...

Safety of Beauveria bassiana (Bals.) Vuill. to Gallus domesticus L. BABT
Haas-Costa,Jucelaine; Alves,Luis Francisco Angeli; Daros,Alaxsandra Aparecida.
Beauveria bassiana, an important insect pathogen was used to evaluate its effect on the feeding, behavior, histology of the digestory system and anatomy of Gallus domesticus. The fungus (strain Unioeste 4) was administrated orally treated with chicken food. Chicken feces were collected, and the birds observed for 28 days. Also, were evaluated the weight of the birds, as well as any sign of intoxication or pathological modification. Tissue samples were withdrawn to test lesions with the optic microscope. There was 100% of survival of the birds, and no behavior alteration or external lesion was found. The test group presented the highest weight gain (1383.9±54.4g). Viable conidia were observed in the feces until 24 h after feeding the fungus, indicating that...
