“…Besides the great potential of this fruit species due to its high vitamin C content, the leaves are also widely used in common medicine as expectorant (FERREIRA et al, 2012;PEREIRA et al, 2019;MUIANGA et al, 2016). It has been reported that these leaves have insecticidal, anti-inflammatory, antimicrobial and antioxidant properties (ANDRADE FILHO et al, 2010).…”

The Anacardium humile A. St.- Hil. fruit tree has productive potential, being their fruits appreciated in the Cerrado region for having characteristic flavor, however, this species is still exploited in an extractive way, being necessary studies for its domestication. The aim of this work was to estimate the leaf area of Anacardium humile. One hundred leaves were collected in the biological collection from a genetic resources field and evaluated for length, width and fresh weight, and scanned at resolution of 300 dpi to determine the leaf area with the aid of the ImageJ image analysis program. Subsequently, a leaf disc with a diameter of 22.27 mm was detached at the basal portion of each leaf, in which the fresh weight of the discs was obtained. Data were submitted to descriptive analysis and the relationship among the features explained by Pearson’s correlation with the software Rbio. The data were also subjected to regression analysis to explain the relationship between leaf area and measurements of width, length and leaf weight, and to fit the proper statistical model with the software Origin. It was concluded that leaf area can be determined by image analysis software and linear measurements are correlated to leaf area.

“…Os autores também descrevem que o ácido anacárdico, extraído de folhas de Anacardium humile, provocou 100% de mortalidade em larvas de 4° estádio nas concentrações até 0,000025 mg/mL. O extrato aquoso de folhas de Anacardium humile (ANDRADE FILHO et al, 2010) nas dosagens de 20; 8; 4; e 0,5 mg/mL provocaram o alongamento do ciclo da fase jovem da moscabranca (Bemisia tuberculata) em comparação com o controle (13,58 dias). A aplicação foi feita por pulverização do extrato aquoso em plantas de mandioca e as ninfas atingidas se tornaram pupas após 20,76; 21,02; 21,81 e 23,43 dias, respectivamente, nas concentrações de 0,5; 4; 8 e 20 mg/mL.…”

Foi investigada a ação repelente do líquido da casca da castanha-de-caju (LCC) Anacardium occidentale L. sobre o caruncho Dinoderus minutus Fabricius, (1775), na Base de Pesquisa em Ciências Agráriasda Universidade Católica Dom Bosco, município de Campo Grande - MS. Colmos maduros de Bambusa vulgaris Schrad (1808), foram coletados de uma touceira local. Destes, foram obtidos doze toletes colocados para secar em estufa a 50±3ºC por 48h. Em seguida foram impregnados, por imersão, durante 24h em concentrações de 0,03; 0,05 e 0,09 mg/mL de LCC. Após as impregnações, os toletes foram desidratados em uma estufa durante 12h a 50±3ºC e distribuídos aleatoriamente em uma arena de acrílico instalada em uma sala de 27 m3. O experimento foi repetido durante cinco dias consecutivos durante 24h cada. Em cada repetição foram liberados no centro da arena 60 carunchos adultos para avaliar a atratividade ou repelência dos mesmos em relação aos toletes. A avaliação contabilizou os carunchos que não conseguiram penetrar nos toletes de bambu. Todas as concentrações repeliram o caruncho-do-bambu, porém, sem diferenças significativas.

“…From this perspective, the presence or synergy of the compounds found in the ethanolic extracts of leaves, stems, and roots are thought to be responsible for the deleterious effects on A. monuste orseis behavior and development. Phytochemical prospecting of various botanical extracts and the influence of the secondary compounds on the biology and behavior patterns of a number of pest arthropods have been discussed (Restello et al, 2009;Andrade Filho et al, 2010;Boiça Júnior et al, 2013). These investigations have shown the detrimental effect of the phenolic compounds, tannins, terpenes and saponins on eggs, larvae, pupae, and adult phases of different insects and mites, in which terpenes are outstanding in all studies.…”

-The objective of this work was to evaluate the phytochemical profile and bioactivity of extracts of Brazilian stinging ("cansanção") nettle (Cnidoscolus urens) on cabbage caterpillar (Ascia monuste orseis). Mortality, larval stage duration, pupal viability and mass, percentage of deformed pupae, and feeding preference were evaluated. The constituent classes of the ethanolic extracts were also identified by analytical thin-layer chromatography (TLC). Ethanolic extracts of leaves and roots at 2% (m/v) and aqueous extract of roots at 20% (m/v) prolonged the larval phase of the insect. The ethanolic extract of leaves at 2% reduced pupal viability, and pupae from all treatments showed reduced masses and generated deformed adults. Except for the ethanolic extract of stem at 2% (m/v), all other extracts showed a deterrent effect on A. monuste orseis larvae. The phytochemical analysis of ethanolic extracts showed the major presence of phenolic compounds, naphthoquinones, anthraquinones, coumarins, anthracene derivatives, terpenes, and steroids, as well as tannins. Aqueous extracts at 20% concentration and ethanolic extracts at 2% of leaves, stems, and roots of cansanção nettle cause larval mortality and also reduce leaf consumption, pupal viability, and pupal mass of A. monuste orseis.
