| ABSTRACT The Brazilian Poplar Moth, Condylorrhiza vestigialis (Guenée), compromises the wood productivity of poplar trees (Populus sp.), mainly affecting the matchstick industry in southern Brazil. Considering the lack of information on rearing techniques for this insect, the objective of this study was to develop an artificial diet to rear C. vestigialis with biological characteristics similar to the wild insects. A properly diet will enable bio-ecological studies and biological control programs using the baculovirus Condylorrhiza vestigialis multiple nucleopolyhedrovirus (CvMNPV). To attain this objective, first, three artificial diets were tested. Only the diet based on corn, wheat germ and yeast as a protein source (Diet 3) was able to supply the... |

| Most common pests of eucalyptus plants in Brazil are leaf cutting ants and defoliating caterpillars. Other groups, eventually, feeding on eucalyptus include Heteroptera and cicadas. The objectives of this work were to identify and to describe attack symptoms of Cephisus siccifolius (Walker 1851) (Hemiptera: Aphrophoridae) on eucalyptus trees in a stand of 25.77 hectares in the State of Bahia, Brazil, where 99.3% of them were attacked by this spittlebug. Damage was more severe on branches and leaves. Tree death was, relatively, low while those cut showed 4.7 colonies of this spittlebug with 21.9 nymphs per colony. Cultural control with the removal of trees attacked was recommended. |

| This study aimed to enlarge the records of forest species attacked by leaf cutting ants in Viçosa, in the state of Minas Gerais. The rising was accomplished in the Campus of the Universidade Federal de Viçosa, being considered only nest active that were cutting and carrying fragments of forest essences. For the study it was evaluated temperature measures and distances of the nest to the attacked tree. As results are observed the occurrence of three quenquém species (Acromyrmex niger Smith, F., 1858, Acromyrmex subterraneus molestans Santschi, 1925 and Acromyrmex subterraneus subterraneus Forel, 1893) and two saúva species (Atta sexdens rubropilosa Forel, 1908 and A. laevigata F. Smith, 1858) attacking 14 forest species. |

| O objetivo deste trabalho foi avaliar a resistência de clones comerciais de E. camaldulensis e E. urophylla ao ataque de Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae). O experimento foi conduzido entre maio de 2007 e abril de 2008, em João Pinheiro, MG, com cinco clones de E. camaldulensis e cinco de E. urophylla. O delineamento experimental foi de blocos ao acaso, contendo 25 plantas por parcela, com quatro repetições. Mensalmente foram coletadas quatro folhas das nove plantas centrais de cada parcela, quantificando o número de ovos e ninfas do inseto. As maiores médias para ovos e ninfas foram observadas para os clones de E. camaldulensis, os quais foram classificados como altamente suscetíveis ao ataque do psilídeo-de-concha. Os clones de E.... |

| The present study aimed at identifying which insect species damages seeds of Erythrina crista-galli L. From November 2012 to January 2013, six E. crista-galli trees were selected in the city of Santa Maria, Rio Grande do Sul State, Brazil, and six pods were taken from each tree. Such pods, properly packaged and identified, were taken to UFSM’s forest pest laboratory and stored in plastic containers until the adults emerged. The emerged specimens were identified as Terastia meticulosalis, which consumed 15.42% of the seeds. This is the first reported occurrence of T. meticulosalis preying on seeds of E. crista-galli in the state of Rio Grande do Sul, Brazil. |

| This study aimed to develop an alternative model of trap for interception with ethanol for flying insects, in order to reduce the costs related to surveys of insects of the subfamily Scolytinae (Curculionidae), conducted in forest ecosystems. The model of trap, called PET-SM, was manufactured with recyclable materials: plastic plate, polyethylene (PET) bottle of two liters, PET bottle of 600 mL, and a hose with alcohol 96 GL used as attractive. Compared to other models used to monitor Scolytinae, the PET-SM model proved to be effective for capture, presenting a greater number of species and offering a lower cost of manufacture. doi: 10.4336/2012.pfb.32.69.115 |

| ABSTRACT Forest species can have their seeds damaged by granivorous insects, especially by those in their larval stage. In this context, this study aims to report the occurrence of Amblycerus species in Cordia trichotoma seeds, to describe their main damage to seeds and effects on germination, as well as their associated hymenopteran parasitoids. Therefore, seven trees were selected in the municipality of Taquaruçu do Sul, RS, Brazil. Fruits were collected weekly from the medium third of the tree crown, from the beginning of their formation until total dehiscence. To examine the damage caused by granivorous insects within the fruits, 15 fruits from each tree were sectioned with a scalpel. Furthermore, 10 fruits from each tree were stored individually in... |

| The life-history and biology of Dirphia araucariae Jones, 1908, including its life fertility table, are here described. Moths were reared in the laboratory under controlled conditions on their host plant, Araucaria angustifolia (Bertoloni) O. Kuntze - Araucariaceae. We describe several life-history traits of the species, namely: developmental period, survival rate, growth rate, fertility, fecundity, sex ratio, cephalic capsule width, and pupal weight. Mean duration of life stages were: egg = 26.78 days; larva = 61.78 days; prepupa = 6.85 days; pupa = 62.46 days; adult = 8.37 days. We found statistically significant differences between sexes for adult, larval and pupal stage duration; larval stage was longer in females while pupal stage was longer in males.... |
