“…We demonstrated that the increased levels of •NO in the treatment of M. rileyi could have caused the death of the insects, through the oxidative stress mechanism, corroborating with described by Branco et al (2014Branco et al ( , 2016. •NO is potentially toxic, particularly involved with oxidative stress (Moncada & Higgs, 2006).…”

“…The latter includes a group of detoxifying enzymes such as superoxide dismutase and catalase. Previous studies have demonstrated that agrochemicals such as glyphosate (Monserrat et al, 2007;Sies, 1993) and even some natural extracts (Branco et al, 2016(Branco et al, , 2014 are able to cause an imbalance between the production of ROS and the antioxidant system, inducing entomotoxic effects by increasing oxidative stress. Oxidative damage to biomolecules, such as lipid peroxidation and protein modifications, can lead to cell death (Cobb & Cole, 2015).…”

Anticarsia gemmatalis is one of the most important pests in world soybean crop. The most common intervention is the application of agrochemicals, such as novaluron and glyphosate. Among biological control agents, much attention has been drawn to entomopathogenic fungi, as Metarhizium rileyi. Here, we examined the changes that occur in the immune system (total and differential hemocyte count), secondary effects (caterpillar morphology), and oxidative metabolism after the caterpillars were exposed to M. rileyi, novaluron or glyphosate. M. rileyi was able to induce changes in the width, length, and weight of A. gemmatalis pupae, along with an increased in the number of defense cells. Novaluron prompt changes the insect’s immunity, and glyphosate caused milder immunological effects. However, it caused significant secondary effects including malformations in pupae and adults, and an increase in nitric oxide (NO) levels. Mortality observed when treating insects with novaluron and malformations due to glyphosate treatments did not occur due to oxidative stress. However, when insects were exposed to M. rileyi, we verified significantly increased levels of NO and concluded that these insects died due to oxidative stress. Our data provide evidence that contributes to better understanding the mechanism of herbicide-fungus interaction in the management of Anticarsia gemmatalis.

“…The dominant tree species in the studied consortium system is the conifer Araucaria angustifolia, a species that produces insect repellent substances (Branco et al 2014), factor which can contribute to the herbivory of other consorted species that lack such mechanisms. In the insect ecology context, a diversification of the entomofauna is expected within the more diverse agroforestry system, which may be in equilibrium because of the environmental stability (Fazolin 1997).…”

Effects of different cultivation systems in leaf traits and herbivory damage in Ilex paraguariensis (Aquifoliaceae)

et al. 2015

Different environmental conditions are crucial to determine many attributes in plants by selective pressures. Plant traits and ecological interactions may present variation in outputs in these distinctive selection scenarios. In south Brazil, yerba mate (Ilex paraguariensis A. St.-Hil.) has been cultivated in monoculture and in consortium systems, differing significantly in lightning intensity and associated plant richness. In this study, three areas of both cultivation systems were monitored to verify the plant outputs in leaf area and herbivory damage. Our results showed that consortium system cultivation presents higher values of leaf area and higher damage by herbivory. Higher leaf area in consortium system corresponds to numerous studies and corroborates the phenotypic plasticity expected for Ilex paraguariensis. On the other hand, the higher leaf damage opposed the hypothesis that greater plant richness should promote the best herbivory control by natural enemies. Despite the higher foliar loss plants cultivated under consortium system present adequate leaf area to farmers. Beside species richness, other plant community traits play important role in mitigation of herbivory.

“…This allelopathic potential seems to serve A. angustifolia on the successional dynamics of Araucaria Moist Forests. Our group has investigated the entomotoxic effect of an aqueous extract obtained from bracts of A. angustifolia on the velvetbean caterpillar Anticarsia gemmatalis (Lepidoptera: Erebidae) [20]. This extract, rich in phenolic compounds, was able to increase the number of malformed pupae (0.15, 1.5 and 7.5 mg), along with a decrease in the emergence of the insects (1.5 and 7.5 mg), and these effects were related with the lipid, protein and DNA damage detected in the larvae via oxidative stress.…”

“…Our group has importantly contributions regarding A. angustifolia biological effects. We reported that bracts (sterile seeds) contain high levels of chemical compounds with important pharmacological actions in several models of study [17][18][19][20]. Despite the different extraction conditions employed in distinct studies, phenolic compounds can be regarded as the major constituents in this particular plant.…”

Araucaria angustifolia is a tree that belongs to Araucariaceae family and it is mainly found in Southern Brazil. This plant has a notable therapeutical history in folk medicine holding great socioeconomic and environmental importance. Until now, some studies were conducted to assess its chemical composition, biological and pharmacological properties. The studies have shown that the bark, knot, needles (leaves), seeds and bracts (sterile seeds) contain high concentrations of active compounds and exhibit different biological effects. In the folk medicine the different parts of this plant are used to treat various types of illnesses, such as shingles, respiratory tract infections, sexually transmitted diseases and some types of wounds. Bearing this in mind, this review focuses on all currently chemical and biological effects already reported for A. angustifolia and provide a novel perspective and useful information for future research.
