| Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea... |

| In several insects, sex-pheromones are essential for reproduction and reproductive isolation. Pheromones generally elicit stereotyped behaviors. In moths, these are attraction to conspecific sex-pheromone sources and deterrence for heterospecific sex-pheromone. Contrasting with these innate behaviors, some results in social insects point toward effects of non-sex-pheromones on perception and learning. We report the effects of sex-pheromone pre-exposure on gustatory perception and habituation (a non-associative learning) in male Agrotis ipsilon moths, a non-social insect. We also studied the effect of Z5-decenyl acetate (Z5), a compound of the sex-pheromone of the related species Agrotis segetum. We hypothesized that conspecific sex-pheromone and Z5 would... |

| The species Helicoverpa armigera is one of the most important polyphagous and widely distributed pests in the world. Its occurrence was recently reported on soybean and cotton, in the states of Goiás, Mato Grosso and Bahia, Brazil. Tomato is also host species of H. armigera, among the 200 registered, being one of the most important crops in the Espírito Santo state. The production of tomatoes is fully dedicated for fresh consumption and the damage caused by H. armigera in fruits make unfeasible marketing. Therefore, this study aimed to record the occurrence of H. armigera in tomato crop in the Espírito Santo state. From February 2012 to October 2013, insects were collected from tomato plants in some producing areas. After insect identification, by... |
