Ocorrência de Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae) no Estado de Goiás

The bronze bug Thaumastocoris peregrinus Carpintero & Dellape (Hemiptera: Thaumastocoridae) was found in Goias state attacking Eucalyptus camaldulensis Dehnh. e E. urophylla S. T. Blake. The insect was detected in the cities of Sao Luiz do Norte, Sao Francisco de Goias and Goiânia.

Morphoagronomic Characterization of Tomato Plants and Fruit: A Multivariate Approach

Consumers in the fresh fruit market choose fruits mainly following criteria related to the external appearance. However, the introduction of new material for planting depends on the productive capacity of the plant as well as on the formation of fruit that meets consumer desires. Given the above, the objective of this study was to morphoagronomically characterize tomato genotypes using multivariate statistics. The genotype seedlings (Ellus, Black Mauri, Green Zebra, Green Tomato, Pomodoro Marmande, Pomodoro Fiorentino, Pitanga, and Black Krim) were transplanted 30 days after sowing. The morphoagronomic characterization of the genotypes was carried out by evaluating plants and fruits. The data were analyzed using descriptive analysis, namely, position and variability measurements. In addition, a multivariate cluster analysis and a principal component analysis were carried out for plant and fruit attributes. The cluster and principal component analyses were efficient in characterizing plants and/or fruits of different tomato genotypes. Such efficiency enhances result interpretation and proposed inferences, with applied relevance for the producers. The genotype Ellus has a combination of morphoagronomic plant and fruit traits superior to other genotypes. Such superior traits enable a high productivity.

The stingless bee mandaçaia (Melipona quadrifasciata Lepeletier) increases the quality of greenhouse tomatoes

The pollination of tomatoes in greenhouses using bees (especially Bombus species) has increased worldwide, providing increased productivity. However, no concrete initiative has been carried out with bees for tomato pollination on a commercial scale, in greenhouses in Brazil. Thus, the aim of this study was to evaluate Melipona quadrifasciata efficiency in pollination and consequent production of tomatoes of different growth habits in greenhouse environment. Two experiments were conducted. The pollen load of the creeping tomato (determined growth) flowers and the fruit quality was quantified in the first experiment, in the greenhouse cultivation treatments with bees, without bees, and in the open environment. In the second experiment, the treatments were carried out with tomato of indeterminate growth in greenhouse with bees and without bees. The bees presented foraging behavior and visitation to tomato flowers. The pollen load for the determined tomato was 433% larger in a closed environment with bees when compared with results obtained in the greenhouse without bees. Fruits produced in greenhouses with bees presented 15% more fresh mass and 41.1% more seeds, than the fruit produced in an open environment. Seed production for indetermined growth tomato was 33% higher when the flower was pollinated and the tomato mass increased up to 16%. The results show the importance of using M. quadrifasciata for pollination in a greenhouse environment. Native bees for pollination of agricultural crops in greenhouse showed promising results, especially for the tomato crop, which is benefited by pollination.

FIRST RECORD OF Tingis americana DRAK, 1992 (TINGIDAE) IN Handroanthus heptaphyllus (VELL.) MATTOS (BIGNONIACEAE) SEEDLINGS IN A GREENHOUSE IN STATE OF GOIÁS

Diseases and pests related to the initial development of native forest species in Brazil are little known. Bedbugs can cause accelerated way of damage to plants, causing damage to the development and even death of the plant. So the aim of this study is to report the first record of Tingis americana Drake, 1922 in seedlings of Handroanthus heptaphyllus (Vell.) Mattos in a greenhouse in the Goias State. H. heptaphyllus had scores chlorosis and necrosis in both the faces of the folioles. After a week of initiation of the infestation, the folioles started to die and fall of the plant, and several seedlings totally lost their leaves. There nymphs and adults (male and female) Tingis americana present on the abaxial surface of the leaves. The Goiás
