| 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 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... |

| 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... |

| 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... |

| 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 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... |

| 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 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... |

| 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... |

| 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.... |
