O gênero Eucalyptus abrange as espécies arbóreas mais utilizadas para reflorestamento no Brasil. Devido ao seu elevado conteúdo de substâncias secundárias, esperava-se que os insetos não causassem sérios danos ao eucalipto. Contudo, muitos insetos, principalmente os da ordem Lepidoptera, tornaram-se sérias pragas na eucaliptocultura. O predador Podisus nigrispinus Dallas (Heteroptera: Pentatomidae) vem sendo utilizado contra insetos herbívoros tais como Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), principal praga do eucalipto, mas não se têm dados sobre seu estabelecimento em áreas de eucalipto. Dessa forma, o objetivo deste trabalho foi avaliar o potencial reprodutivo e sobrevivência de P. nigrispinus sobre T. arnobia proveniente de eucalipto e larvas de Tenebrio molitor L. (Coleoptera: Tenebrionidae) provenientes de criação massal em laboratório. Os aspectos biológicos de P. nigrispinus foram melhores sobre pupas de T. molitor em comparação aos indivíduos criados sobre lagartas de T. arnobia. Provavelmente, as lagartas de T. arnobia estão seqüestrando as substâncias secundárias das plantas de eucalipto e utilizando em sua defesa contra predadores como P. Nigrispinus, e se estes inimigos naturais não estiverem adaptados a tais compostos, a sua performance no controle da praga e no seu próprio desenvolvimento podem ser afetados negativamente.

ABSTRACT Objectives: The objective of this study is to compare the various nonlinear and time series models in describing the course of the coronavirus disease 2019 (COVID-19) outbreak in China. To this aim, we focus on 2 indicators: the number of total cases diagnosed with the disease, and the death toll. Methods: The data used for this study are based on the reports of China between January 22 and June 18, 2020. We used nonlinear growth curves and some time series models for prediction of the number of total cases and total deaths. The determination coefficient (R2), mean square error (MSE), and Bayesian Information Criterion (BIC) were used to select the best model. Results: Our results show that while the Sloboda and ARIMA (0,2,1) models are the most convenient models that elucidate the cumulative number of cases; the Lundqvist-Korf model and Holt linear trend exponential smoothing model are the most suitable models for analyzing the cumulative number of deaths. Our time series models forecast that on 19 July, the number of total cases and total deaths will be 85,589 and 4639, respectively. Conclusion: The results of this study will be of great importance when it comes to modeling outbreak indicators for other countries. This information will enable governments to implement suitable measures for subsequent similar situations.

AbstractVentral nerve cord severence in newly emerged females of Tenebrio molitor L. resulted in a rate of oocyte production significantly higher than in normal, mated females and much higher than in intact virgins. This suggests that some nervous, inhibitory factor normally controls oocyte production. Mating partially suppresses this inhibitory mechanism, but the higher rate of oocyte production in females with severed nerve cords indicates that the inhibitory mechanism is exercising some control over oocyte production at all times. A sequence of events in the control of oocyte production in Tenebrio is proposed.
