Plectris alienaChapin, 1934, a white grub that promotes serious damage to a variety of crops in North America and Australia, has been reported for the first time in Brazil. Larvae and adults of P. aliena were recorded in sugarcane crops in the state of Mato Grosso do Sul, sampled by trenches in the soil with light traps, respectively, during 2012 and 2013. Root consumption was also determined for the first, second and third instar larvae. The species is univoltine; adults were found mainly in Aug and the peak of third instar larval density was in Apr in all fields sampled. Pupae and adults of P. aliena were observed in the soil profile at depths of up to 60 and 80 cm, respectively. Larvae of P. aliena of the second and third instar consumed the primary and secondary roots of sugarcane, causing serious damage. Third instar larvae consumed 916 mg of root fresh matter, representing 72 % of the sugarcane root system. These results assist in furthering the understanding of its larval dynamics in the soil and provide support for Integrated Pest Management. |

Abstract: There is a need to enhance agricultural intensification and diversification by establishing alternative crop-livestock-forestry systems. Our objective was to compare the production and physiological characteristics of corn (Zea mays L.) either intercropped with Marandu palisadegrass [Brachiaria (syn. Urichloa) brizantha (Hochst. ex A. Rich.) R. D. Webster] growing in full sun (FS), or in a crop-livestock-forestry with single-row (CLFs) and triple-row (CLFt) groves of Eucalyptus urograndis (hybrid of Eucalyptus grandis W. Hill ex Maiden and Eucalyptus urophylla S. T. Blake). In the CLFs and CLFt, the trees were spaced at 37 m (90 tree ha−1) and 30 m (135 tree ha−1), respectively. The experiment was carried out for 2 years in a randomised complete block with three replications in a strip-split-plot arrangement with measurements at 5 sites between groves (7 and 13 m on the south face, central, and 7 and 13 m on the north face). The forage mass for full sun, CLFs, and CLFt was 10.9, 9.5, and 6.2 Mg DM ha−1 in 2017 and 28.9, 21.5, and 14.0 Mg DM ha−1 in 2018, while the grain yield was 3.38, 3.34, and 1.66 Mg DM ha−1 in 2017 and 7.90, 4.66, and 2.55 Mg DM ha−1 in 2018. The forage mass (10.1 Mg DM ha−1 in 2017 and 23.9 Mg DM ha−1 in 2018) and grain yield (3.3 Mg DM ha−1 in 2017 and 5.0 Mg DM ha−1 in 2018) in the central and 13 m north distances were greater than in the 7 m north and south, with less light transmission and red: far-red ratio. We concluded that corn intercropped with palisadegrass in an integrated crop-livestock-forestry system was negatively affected by the reduction in radiation transmission, resulting in reduced corn height, forage mass, and grain yield than in the full sun.
