Bemisia tabaci is an agricultural pest of worldwide distribution that causes serious damage to several crops. It is of crucial importance to control this pest, especially for large-scale production. Accordingly, formulations based on essential oils of pesticidal action are potentially promising in the agricultural sector. Additionally, the nanoencapsulation of these bioactive compounds promotes their protection from environmental degradation and prolongs their biological activity. Here, we develop PCL (poly-ε-caprolactone) nanoparticles containing essential oils of Xylopia aromatica leaves and fruits and evaluate their insecticidal effect in B. tabaci Middle East Asia Minor 1 biotype B. The average yields of essential oils from leaves and fruits of X. aromatica were 0.05 and 0.80%, respectively. The major compounds in the essential oil of leaves were bicyclogerma-crene (44.80%), α-pinene (8.23%) and β-pinene (7.75%) while in fruits were α-pinene (35.40%), β-phellandrene (31.05%) and β-pinene (22.51%). The PCL nanoparticles containing the essential oils exhibited encapsulation efficiency of 95% and particle diameter smaller than 500 nm. Biodegradable nanospheres substantially protected the essential oils from accelerated degradation caused by UV light and also prevented possible phytotoxic activity of the in natura essential oil from leaves of X. aromatica in high concentrations, probably due to the gradual release. In natura and nanoencapsulated essential oils from leaves and fruits decreased (up to 98%) the oviposition of B. tabaci in common bean leaves. Our results indicate that both in natura and nanoencapsulated oils of X. aromatica may potentially be used as alternative to the chemical control of B. tabaci.

Abstract: The growing demand for soybean has led producers to adopt different plant arrangements. However, this technology information in Cerrado conditions is scarce and further studies in order to understand the effects of soybean crop are necessary. Therefore, the objective of this study was to evaluate different cropping systems, with and without addition of plant population using a soybean variety of semi determinate growth habit in Brazilian Cerrado conditions. The experiments were carried out in the crop years 2013/14 and 2014/15 in Rio Verde - GO, Brazil, in randomized block design with 4x2 factorial arrangement, consisting of four sowing systems (traditional; reduced; double rows and cross) associated to two plant populations (recommended and increase of 33%) of the Anta 82 RR® variety. The results showed that in the 2013/14 season due the better water distribution, the use of double row implantation system presented greater grain yield than the others. Also, with lower rainfall, the 2014/15 season was not influenced by implantation system. The increase in plant population to 665,000 plants ha-1 demonstrated that the densification in the semi-determinate soybean variety was not an interesting technique. |
