| ABSTRACT Thaumastocoris peregrinus (Hemiptera, Thaumastocoridae) is a phytophagous pest of eucalyptus plantations. It was introduced in Brazil in 2008, and expanded rapidly due to its adaptive capacity to different climatic conditions. Eucalyptus has been planted in the Brazilian Amazon since the 1980s, being used in silvopastoral systems and for cellulose production. Since its introduction in the southernmost Brazilian state of Rio Grande do Sul, T. peregrinus has expanded its geographical distribution to 117 municipalities in states in the south (Rio Grande do Sul, Santa Catarina and Paraná), southeast (São Paulo, Espirito Santo, Rio de Janeiro and Minas Gerais), mid-west (Mato Grosso do Sul and Goiás) and northeast (Sergipe) of the country. Here we... |

| This study aimed to evaluate the oviposition preference of the Neotropical brown stink bug, Euschistus heros (F.) on artificial substrates of different colors (felt woven). For this, ten pairs of stink bugs were transferred into plastic pots. Each pot contained seven felts of 6x20 cm (100% polyester-atoxic) of different colors (white, black, blue, green, red, yellow and brown). The pots were evaluated daily for three weeks (21 days) being counted the number of eggs, clutches and eggs per clutch for each color of felt. The choice test was set in a completely randomized design. Data obtained was submitted to the analysis of variance and means were compared by Scott-Knott test at 5% probability. During the evaluation were produced 7074 eggs distributed in 977... |

| The leafminer Liriomyza sativae Blanchard is an important insect pest on melon crops in Brazil. However, the information about its biology on melon (Cucumis melo L.) is scarce. Therefore, the aim of this research was to know some biological aspects of this pest, reared on melon plants, under laboratory conditions at 25°C. Our results showed that the biological cycle of L. sativae lasts 15.9±0.04 days (egg-adult), namely: egg (2.7±0.01 days), larva (4.1±0.03 days) and pupa (9.1±0.03 days). The sex ratio is 0.51 and the females live (19.3±1.09 days) longer than males (16.2±0.96 days). These results can help in the integrated management of L. sativae on melon crops and improve the systems for rearing this leafminer in laboratory. |

| ABSTRACT Bermudagrass (Cynodon dactylon cv. Jiggs) is an important food source for dairy cattle in the semi-intensive milk production systems most often used in southern Brazil. Although many insect pests are associated with feed grasses, we report here the first occurrence of the fly Atherigona (Atherigona) reversura Villeneuve, 1936 (Diptera: Muscidae) feeding on bermudagrass in Brazil. This potential pest was observed in April 2015 in three localities (Abelardo Luz, Palmitos, and Videira) in western Santa Catarina, in southern Brazil. The infested plants had senescent and necrotic terminal leaves that reduced plant growth. New growth had to sprout new tillers from basal nodes, which resulted in a reduced plant growth rate. We also provide a... |
