A diversificação da vegetação reduz o ataque do bicho-mineiro-do-cafeeiro Leucoptera coffeella (Guérin-mèneville) (Lepidoptera: Lyonetiidae)?
Provedor de dados: 82
Autores: Amaral,Dany S; Venzon,Madelaine; Pallini,Angelo; Lima,Paulo C; DeSouza,Og.
The effects of increasing plant diversity on the population of the coffee leaf-miner Leucoptera coffeella (Guérin-Mèneville) were investigated in two organic coffee production systems. One system consisted of coffee intercropped with banana trees (shaded system) and the other one of coffee intercropped with pigeon pea (unshaded system). The increase in plant diversity on both systems was achieved via introduction of green manures such a perennial pea nut, sunn hemp and Brazilian lucerne. The population of L. coffeella, predation and parasitism of L. coffeella mines were biweekly evaluated during eight months. The increase in plant diversity on both systems did not affect the attack of L. coffeella on coffee leaves and the mine parasitism rate. However,...

Efeito da profundidade de aplicação e da distribuição de inseticidas líquidos no controle de cupins de montículo em pastagens (Isoptera: Termitidae)
Provedor de dados: 82
Autores: Fadini,Marcos A. M.; DeSouza,Og; Fanton,César J.
Foi testada a eficiência de duas profundidades de aplicação de cupinicidas líquidos para o controle de cupins de montículo Cornitermes sp. (Isoptera: Termitidae) em pastagens na região Sul de Minas Gerais. Estes aplicadores diferiam basicamente quanto à profundidade e distribuição da calda cupinicida dentro do ninho, sendo um aplicador de tubo curto e outro de tubo longo e perfurado. Os resultados mostram que, o aplicador e tubo longo e perfurado apresenta maior eficiência de controle de cupins de montículo em pastagem e que a profundidade e distribuição de aplicação da calda cupinicida interfere na taxa de mortalidade das colônias. O uso de um aplicador com tubo longo, pode ser uma estratégia adequada para o efetivo controle de cupins de montículo, quando...

Teaching entomology: moving from paternalism to active learning
Provedor de dados: 44
Autores: DeSouza,Og; Lima,Eraldo; Reis Jr.,Ronaldo; Pallini,Ângelo.
We propose a shift in the traditional way to teach Entomology for undergraduate and postgraduate courses. We envisage a system in which undergraduate and postgraduate students interact, discussing Entomology outside the classroom. This would get them to actively seek for knowledge, rather than being paternalistically told how they should learn. Such a system does not preclude lectures as a didactic strategy, nor it rules out lecturers as responsible for instructorship. On the contrary, we believe lectures and discussion outside classroom are complementary for effective teaching. Our results show that undergraduate and postgraduate students who interact outside classroom are able to get better grades even when submitted to traditional written tests....

Reproduction and survival of Muscina stabulans under laboratory conditions
Provedor de dados: 65
Autores: Krüger,Rodrigo Ferreira; Ribeiro,Paulo Bretanha; Erthal,Simone Giehl; DeSouza,Og.
This is the first published report concerning reproduction and survival using life table analyses of fertility and survival for Muscina stabulans maintained under laboratory conditions with artificial diets. The intrinsic rate of growth, reproduction rate and average generational time were obtained, suggesting a rapid population growth under these rearing conditions. These findings permitted the creation of time models of survival and oviposition, as well as a quantitative estimate of the adaptation capacity of this species.
