O objetivo deste trabalho foi avaliar a suscetibilidade das lagartas Anticarsia gemmatalis (Lepidoptera: Erebidae) e Chrysodeixis includens (Lepidoptera: Noctuidae) às proteínas Cry1 e Vip3A, bem como determinar se há a interação entre essas proteínas no controle das duas espécies. Bioensaios com as proteínas isoladas e em combinações foram realizados, e as concentrações letais CL50 e CL90 foram estimadas para cada condição. As proteínas Cry1Aa, Cry1Ac e Vip3Af foram as mais efetivas no controle de A. gemmatalis, enquanto Cry1Ac, Vip3Aa e Vip3Af foram mais efetivas no de C. includens. As proteínas Cry1Ac e Cry1Ca causaram maior inibição do desenvolvimento das larvas sobreviventes à CL50, em ambas as espécies. Combinações entre Vip3A e Cry1 apresentam efeito sinérgico no controle das espécies e a combinação Vip3Aa+Cry1Ea destaca-se no controle de A. gemmatalis e C. includens. Essas proteínas combinadas são promissoras na construção de plantas piramidadas, para o controle simultâneo das pragas.

This article mainly aims at addressing issues of the complexity and dynamics of beliefs in collaborative contexts for language teaching and learning, such as Teletandem. On the assumption that beliefs are dynamic and can be (re)signified, we present some of the results of a research about the interaction of beliefs of two Teletandem partners, a Brazilian and an Italian undergraduate student, addressing moments of convergence and divergence, as well as their possible origins and (re)significations from lived experiences. The results show how the Teletandem context can become a field for conflicts and clashes of beliefs and how the mediation as well as the relationship between the participants becomes essential for the conduction of language learning in collaborative environments.

Collective intelligence is an interdisciplinary subject and it has been explored for many different knowledge areas. As a proposal totally tied to the concept of information and information technologies and communication, it is considered as relevant the discussion about the topic within the scope of Information Science. Therefore, a descriptive and exploratory study was carried out from Pierre Levy's work, identifying the precepts of collective intelligence and its ambiences and implications. The research is documental, focusing on determining the state of the art of the production about collective intelligence, verifying what was produced by Pierre Lévy and by other authors about the subject, in order to point out what possible interventions of Information Science on studies about collective intelligence. The research showed that that in the field of Information Science there is little research on the theoretical level about collective intelligence. Nevertheless, discussions about the representation and organization of collective intelligence in digital environments have been recurrent in the present, thus opening new fields of approach between Information Science and conceptual research and practice in collective intelligence.
