| A high incidence of the bug Sthenaridea carmelitana (Carvalho) on sorghum, Sorghum bicolor, and on corn, Zea mays, was observed in the field, in Sete Lagoas, MG. In laboratory, using a free choice test, the bugs preferred to feed on sorghum grain (from milk to hard stage) than on other plant parts like panicle (without grain) or leaf. S. carmelitana preferred to feed on sorghum than on corn. |

| The coreid bug Leptoglossus zonatus (Dallas) is an important pest that can feed on several economically important plants such as corn, soybean, sorghum, cotton, among others. In Campinas, São Paulo state, Brazil, nymphs and adults of L. zonatus have been found mainly on corn Zea mays L. In field work carried out during the month of May, at the end of the vegetative cycle of corn, adults and nymphs of L. zonatus were observed feeding on Spathodea campanulata Beauv (Bignoniaceae), a tree of African origin widely used in urban green belts, parks and street in Brazilian cities.It is possible that L. zonatus can use the plant S. campanulata as an alternative food resource during the periods when corn is not present or is not at the right vegetative stages. |

| Since 1988, the medfly Ceratitis capitata (Wiedemann) was described infesting papaya (Carica papaya) cv. Sunrise Solo in North of the State of Espírito Santo, Brazil. Two experiments were carried out to determine the infestation of C. capitata and Anastrepha obliqua (Macq.) in papaya fruit, healthy and infected by sticky disease. In the 1st experiment (forced infestation), no infestation of C. capitata in the healthy fruits was observed, and 60.6 pupae/fruit were obtained in the infected fruit. For A. obliqua, the infestation index was 10.3 and 72.4 pupae/fruit for healthy and infected fruit respectively. In the 2nd experiment (inoculated eggs), the infestation index for C. capitata was 4.0 and 6.3 pupae/fruit and for A. obliqua 10.1 and 10.4 pupae/fruit,... |

| We inventoried and characterized the kinds of gall, gall-inducing insects and host plants from Serra Geral between August 2013 and July 2014. Two phytophysiognomies, cerrado sensu stricto and caatinga-cerrado, were examined monthly along transects during ca. 4 hours per visit, totaling 48 hours of sampling effort. A total of 49 gall morphotypes were found on 14 species of host plants in 18 genera and 13 families. Fabaceae and Malpighiaceae were the families with the most galls, with 22 and 10 gall morphotypes, respectively. The genera of host plant with the greatest richness of galls were Copaifera L. (n=10), Bauhinia Benth. (n=6), and Mimosa L. (n=5). Galls were found on leaves, buds and stems. The majority of the galls were globoid, glabrous, isolated,... |

| Our goal was describe the gall richness through the characterization of their external shapes and occurrence patterns in their host plants from Parque Estadual da Serra do Cabral. In a universe of 34 families, 64 genera and 89 plant species, 47 gall-inducing insects in 21 families, 32 genera and 39 host plant species were recorded. The families, which hosted higher gall richness, were those with highest abundance. Asteraceae represented 33% of the species collected followed by Malpighiaceae 8% and Fabaceae 8%, each one concentrating 25%, 19% and 8% of gall-inducing insects, respectively. The organ most attacked was the leaf (51%), followed by the stem (42%) and the terminal branch (4%). Ninety-six percent (96%) of galls were glabrous. Only 25.5% of the... |

| This is the first study about galls, gall makers and associated fauna of the Ecological Station of Jataí. Galls are plant structures formed by abnormal growth of cells, tissues or organs induced by several organisms, as fungous, nematoids and insects. Five areas of the conservation unity, two in the phytophysionomy of cerrado in regeneration and three in the cerradão area were studied, totalizing 69 morphotypes of galls on 41 host species from 24 families. This is the first record of Annonaceae as the richest family in morphotypes in Brazil; 34 gall makers and associated fauna were identified, which 23 Diptera (67.4%), eight Hymenoptera (23.5%), two Hemiptera (5.8%) and one Thysanoptera (2.9%). Were described 41 new morphotypes of gall and made the first... |

| Gall-inducing insects are very specious in vegetations of southeastern Brazil. Our goal was describe the gall richness by characterizing their external forms and their patterns of occurrence on host plants. Samples were collected from Campos de Altitude at four regions of the Mantiqueira Range: 1) Parque Estadual da Serra do Brigadeiro, 2) Parque Nacional do Caparaó, 3) Parque Estadual do Ibitipoca, 4) Parque Nacional do Itatiaia. We found 93 gall species within 13 families, 30 genera and 50 host plant species. We recorded 38 gall species in Parque Estadual da Serra do Brigadeiro, 21 in Parque Nacional do Caparaó, 23 in Parque Estadual do Ibitipoca and 20 in Parque Nacional do Itatiaia. Asteraceae represented 33% of the species collected, followed by... |

| The external morphology of the sensilla, including pores and permeable points on the cuticle of the antennae of adults of Neomegalotomus parvus (West.) (Heteroptera: Alydidae) was investigated with regard to their olfactory function. Behavioural evidence of olfaction, the importance of the different antennal segments in locating the host under still-air, and the responses of the insects to plants' scents and to pheromones in wind assays were also studied. With the scanning electronic microscope mechanoreceptor sensilla were found on the four segments of the antennae of N. parvus. The density of the sensilla was greater on the 4th segment. On the apical segment, sensilla with olfactory morphological traits were observed. Bugs with intact antennae located... |

| A circular cryptic plasmid named pPAGA (2,734 bp) was isolated from Pantoea agglomerans strain EGE6 (an endophytic bacterial isolate from eucalyptus). Sequence analysis revealed that the plasmid has a G+C content of 51% and contains four potential ORFs, 238(A), 250(B), 131(C), and 129(D) amino acids in length without homology to known proteins. The shuttle vector pLGM1 was constructed by combining the pPAGA plasmid with pGFPmut3.0 (which harbors a gene encoding green fluorescent protein, GFP), and the resulting construct was used to over-express GFP in E. coli and P. agglomerans cells. GFP production was used to monitor the colonization of strain EGE6gfp in various plant tissues by fluorescence microscopy. Analysis of EGE6gfp colonization showed that 14... |

| The effect of six natural diets on the development and reproduction of Argyrotaenia sphaleropa (Meyrick) was measured under laboratory conditions, at 23 ±1ºC temperature, 70 ± 10% RH, and photoperiod of 16L:8D. Larvae were reared on three types of diet (spring leaves, summer leaves and fruits) from two different host plants (apple tree and grapevine). Larval development, number of instars, survival, weight of pupae, fecundity, and fertility varied as a function of diets. The shortest time span of larval development, the greatest pupal weight, and the greatest adult fecundity and fertility was observed on insects feeding on spring apple leaves. The duration of larval development was longer on fruits than on leaves. The lowest larval survival occurred on... |

| Laboratory and greenhouse experiments were carried out to study food and oviposition preference by Phyllophaga cuyabana (Moser) on different plant species as Cajanus cajan L. (pigeon pea), Crotalaria juncea L. (sun hemp), Crotalaria spectabilis Roth (showy crotalaria), Crotalaria ochroleuca G. Don (slenderleaf rattlebox), Glycine max [L.] Merrill (soybean), Gossypium hirsutum L. (cotton), Helianthus annuus L. (sunflower), Stizolobium aterrimum [Mucuna aterrima] Piper & Tracey (velvetbean) and Zea mays L. (mayze). In no-choice experiments, the number of eggs layed in sunflower, C. juncea and soybean was larger compared to cotton. Despite the fact that the adults did not discriminate among plants, in dual-choice test, the proportion of eggs layed and... |

| The development and reproduction of the citrus leafminer (CLM), Phyllocnistis citrella Stainton, were evaluated in six citrus genotypes in order to identify genotypes with resistance traits that could be applied in a program for the development of citrus varieties resistant to the citrus leafminer. Tests were conducted under controlled laboratory conditions (25 ± 1ºC, 70 ± 10% RH, and 14h photophase). Seedlings of each genotype tested were infested with eggs obtained from a stock colony of CLM maintained on 'Cravo' lemon (Citrus limonia L. Osbeck), and the duration and survival of the eggs, larval and pupal stages, pupal size and weight, fecundity and longevity of adults, and sex ratio were evaluated. No influence was observed on the duration and survival... |
