| Efficacy of essential oils from rhizomes of Alpinia conchigera, Zingiber zerumbet and Curcumazedoaria to repel Sitophilus zeamais and Tribolium castaneum at 0.003, 0.03, 0.15, 0.31, 0.63 and 1.27 μL/cm2 by Petri-dish choice bioassay indicated that the most efficiency was found in C. zedoaria oils (91.5%) followed by Z. zerumbet oils (89.4%) and A. conchigera oils (78.1%). For T. castaneum, A. conchigera oil (97.4%) was the most effective one, followed by C. zedoaria oil (95.3%) and Z. zerumbet oil (93.0%), respectively. Furthermore, the residual of three essential oils were also estimated at 1.27 μL/cm2 and the results demonstrated that Alpinia conchigera and Z. zerumbet oils strongly repelled both insects till the end of experiment (8 days) while C.... |

| Aleurodicus cocois (Curtis, 1846), the coconut whitefly, is a very damaging pest in Peru, mainly in avocado trees (Persea americana Mill.). It has been determined that entomopathogenic fungi can infect and kill white flies and can be used as biological control agents. The object of this research was to determine if there is any synergic action of the entomopathogenic fungi Paecilomyces fumosoroseus (Wize) Brown & Smith 1957 and Verticillium lecanii (Zimmerman, 1892) Viégas 1939, in controlling A. cocois. Plastic sterile dishes were prepared where 5 mL 2% agar were used for each stage; leaves infested with A. cocois were placed upon these. Three different treatments were applied by sprinkling: P. fumosoroseus (P), V. lecanii (V) or the mixture of... |

| ABSTRACT: Cyclocephala flavipennis Arrow, 1914 (Coleoptera: Melolonthidae), popularly known as white grub, is an insect widely disseminated in the South Region of Brazil. Despite the frequent occurrence of this white grub in areas cultivated with winter cereals, it is generally not considered a pest, since it feeds on straw and dead plant material. However, in 2015 and 2016, this insect has been identified as the damage-causing agent in the perennial winter pastures in Lages, Santa Catarina, Brazil. Damage was observed in patches and caused reduction in root depth and mass, resulting in loss of vigor, accelerated senescence in aerial parts, and death of tillers in Festuca arundinacea Schreb. and Dactylis glomerata L. plants. |

| The occurrence of Anastrepha aczeli Blanchard and Anastrepha similis Greene (Diptera: Tephritidae) is recorded in the state of Minas Gerais, Brazil. Specimens of A. aczeli were found in traps placed in orchards of acerola, Malpighia emarginata DC (Malpighiaceae), and citrus, Citrus sinensis (L.) Osbeck (Rutaceae), and A. similis was obtained in traps placed in citrus orchards located in the county of Bambuí, MG, Brazil. |
