Twelve new species of Tomoplagia reared from capitula of Asteraceae collected in southern and southeastern Brazil are described (T. achromoptera n. sp., T. aczeli n. sp., T. bicolor n. sp., T. brasiliensis n. sp., T. cipoensis n. sp., T. dimorphica n. sp., T. grandis n. sp., T. interrupta n. sp., T. matzenbacheri n. sp., T. rupestris n. sp., T. variabilis n. sp., and T. voluta n. sp.). Five of these species have highly atypical wing markings, differing from the usual pattern for the genus, which includes five oblique yellow bands. Aberrant wing patterns were previously known in only three species. All the new species were reared from capitula of Vernonieae, confirming this Asteraceae tribe as the main host group of Tomoplagia species. Of these new species,... |

The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated. The digestive tract contents of insects captured in pheromone traps in two cotton fields and two areas of native vegetation (gallery forest and cerrado sensu stricto) were analyzed. The insect was captured all through the year only in the cerrado. It fed on pollen of 19 different plant families, on Pteridophyta and fungi spores and algae cysts. Simpson Index test showed that the cerrado provided... |

The fall army worm Spodoptera frugiperda (Smith) is a migratory important pest of corn, sorghum, rice, grass and bermudagrass in North and South America. This species has diverged into two genetically differentiated but morphologically identical strains, "the rice" and "the corn". They have been analyzed by sequencing the genes cytochrome oxydase I, II and ITS1 from populations from the United States and Brazil. However, no such studies were performed in Colombia. In here, we identified 43 haplotypes by sequencing a fragment of the COI gene from 102 individuals, of which 40 had already been identified as the "corn" and "rice" strains or to their hybrids from Tolima, and the rest were collected from corn, cotton, sorghum, grass and rice fields in other... |

The effect of seven natural diets on the development and reproduction of Bonagota cranaodes (Meyrick) was evaluated under laboratory conditions. The experiments were carried out at the temperature of 23 ± 1ºC, with 70 ± 10% of RH and a photoperiod of 16:8h (L:D). The larvae were reared on apple, grapevine and honeysuckle (Lonicera japonica). On the first two foods three types of diet were used: spring leaves, summer leaves and fruits. The number of instars varied from five to seven. The larvae reared on apple leaves had, in general, fewer instars than those reared on grapevine and honeysuckle leaves. The duration of larval development differed between diets. The larvae reared on spring apple leaves showed the shortest duration, and those on fruit the... |

Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host plants. Saccharosydne subandina can be distinguished from its congeners by the following combination of features: uniformly light green-yellowish color with a distinctive rounded black macula on both genae; vertex 1.5x longer than wide, and projecting beyond eyes almost one half of its length; parameres divergent with internal and external angles acute; and... |

The adult female of Neohydatothrips denigratus (De Santis) is redescribed, the male and immature stages (larva, prepupa and pupa) are described for the first time, and aspects of the biology of this species are made known. Descriptions of the different stages of development were made from laboratory-reared specimens on using twigs of Phaseolus vulgaris as a feeding and oviposition substrate. Neohydatothrips denigratus undergoes its life cycle on the leaves of P. vulgaris, no immature stages were found in flowers or fruits. Under controlled conditions (21 ± 2ºC; 80 ± 4% RH; photophase: 12h), this species needed 21.6 ± 1.60 d to complete development (egg: 7.0 ± 1.00 larva I: 3.7 ± 1.40; larva II: 4.2 ± 1.10; prepupa: 1.8 ± 0.70, pupa: 5 ± 1). Longevity was... |

Abstract Insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). Galls are changes in the pattern of growth and development of plant tissues or organs in response to the action of an inducing organism, usually an insect. The goal of the present study was to inventory the insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). The collections were carried out along all the trails, totaling 16 hours of sampling. Forty-three morphotypes of insect galls were found in 24 plant species (18 genera and 15 families). Sapindaceae and Euphorbiaceae were the most richness host plant families. Six new records of host plant species are presented: Senefeldera verticillata (Vell.) Croizat. (Euphorbiaceae), Inga acuminata (Fabaceae), Ocotea elegans... |

Oxylopsebus brachypterus new genus and species from humid tropical forest, Department of Santa Cruz, Bolivia is described and illustrated. Although with reduced elytra, the genus is placed in Oxycoleini based on the following characters: female urosternites modified, the first as long as the second to fourth together, the second with a brush for covering the eggs with detritus after being laid; the male with six visible urosternites, the first twice as long as the second; eyes with superior lobes; prothorax divergent behind, disc of pronotum with calli; procoxal cavities closed behind. Oxylopsebus gen. nov. would seem to fall between the Oxycoleini and Psebiini and be less closely related to the Obriini and Luscosmodicini, the four tribes in which the... |

Abstract: The objective of this work was to analyze the faunistic composition of the insect pests that occur during the fallow period in cotton (Gossypium hirsutum) crop residues in the state of Mato Grosso do Sul, Brazil. The study sites were the municipalities of Alcinópolis, Chapadão do Sul, Costa Rica, Aral Moreira, Dourados, and Sidrolândia. A sampling design with two replicates per municipality was used. Each replicate comprised 100 random points, and each point corresponded to a cotton plant that was entirely inspected, to count the insect pests on it. The obtained fauna was analyzed and a rarefaction curve of the species was generated. During the evaluation period, a total of 23 species were recorded in the cotton crop residue, and the most... |

A busca por informações sobre as espécies de cerambicídeos associadas à Ocotea puberula (Rich.) Nees (Lauraceae) em galhos cortados por Oncideres cervina Thomson, 1868 (Cerambycidae: Coleoptera), motivou o presente estudo. De 49 galhos cortados do hospedeiro na região central do estado do Rio Grande do Sul, determinou-se a emergência de cerambicídeos com avaliações bissemanais. Além de O. cervina, o serrador dos galhos, foram observadas três espécies de cerambicídeos, Trestonia capreola (Germar, 1824), Dihammaphora signaticollis Chevrolat, 1859 e Tropidozineus rotundicollis (Bates, 1863) (Cerambycidae: Coleoptera), sendo para duas o primeiro registro de planta hospedeira desta família botânica. O período de emergência dos cerambicídeos de galhos de O.... |

Piperaceae species have been placed among the basal angiosperm and are adapted to a variety of habitats including moist forests, secondary vegetation and dry high lands. The major anatomical/morphology features are of small trees, vines, and shrubs for Piper species, while the epiphytic and succulent characteristics are predominant forms among Peperomia species. Their secondary chemistry can be mostly represented by amides, phenylpropanoids/lignoids, and chromenes in addition to a phletoria of biosynthetically mixed-origin secondary compounds. Although several amides and lignans are known as insecticides, several phytophagous insects, among which some considered pests of economic importance, have been observed feeding vigorously on Piperaceae species.... |

Abstract Heteropsylla caldwelli Burckhardt (Psyllidae, Ciriacreminae) is reported for the first time from Brazil (States of Minas Gerais, Paraná, Rio Grande do Sul) from Enterolobium contortisiliquum (Vell.) Morong. The earpod tree, from Albizia edwallii (Hoehne) Barneby and J.W. Grimes and Senegalia polyphylla (DC.) Britton (Fabaceae, Mimosoideae), all previously unknown hosts. The population dynamics of the psyllid were investigated in a seven-year-old plantation of E. contortisiliquum in an abandoned open-pit coal mine in Candiota, Rio Grande do Sul during two years. The population showed peaks in spring and summer, correlating directly with the mean air temperature and the population size of microhymenoptera. |
