Abstract: The objective of this work was to identify and carry out a field testing of the sex pheromone composition of the mahogany shoot borer, Hypsipyla grandella, from a population in Southern Brazil. Abdominal glands of H. grandella females were excised and extracted using n-hexane; the gland extracts were analysed by gas chromatography (GC-FID and GC-MS). Wind-tunnel and electrophysiology experiments were conducted to evaluate the role of gland compounds in the mating behavior of H. grandella males. In the field, pheromone traps containing the identified pheromone were tested. In addition to the two previously identified compounds - (9Z,12E)-tetradecadien-1-ol and (9Z,12E)-tetradecadienyl acetate -, in insects from Central America populations, two...

Euschistus heros mass rearing technique for the multiplication of Telenomus podisi 86
Silva,Cleonor Cavalcante; Laumann,Raul Alberto; Blassioli,Maria Carolina; Pareja,Martin; Borges,Miguel.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults were determinated. Survivorship of nymph to adult was the highest (89%) at density 100 eggs per dish. Adult survivorship was independent of density, and 100 couples per cage were the best to improve quality of the produced progeny. In these conditions, fecundity was 160.8±9.28 eggs per female, and a total of 8,950±456 eggs per cage per month was produced. Two hundred couples per cage showed a negative...

Comparative biology of two congeneric stinkbugs, Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae) 86
Silva,Cleonor Cavalcante Alves; Laumann,Raul Alberto; Moraes,Maria Carolina Blassioli; Aquino,Michely Ferreira Santos de; Borges,Miguel.
The objective of this work was to compare the biology of Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae), two species of stinkbugs that occur as secondary pests in soybean. Life table procedures were used for evaluating nymphs, and fecundity tables for evaluating adults, in order to establish the demographics of the two species. The two species have similar demographic parameters, and the development of immature stages, from egg to adult, had similar duration periods of approximately 30 days. In both species, eggs and second-instar nymphs were the stages with higher mortality. Total egg production did not differ between females of both species. Fecundity and survival curves for adults showed similar trends in both species. However, C. ubica...
