| Para se conhecer a ação de misturas de alachlor com diuron ou com cyanazine para o controle de monotiledôneas e de dicotiledôneas em cultura de algodão 'IAC-17', foi conduzido um experimento de campo, em 1981/82, em Mogi-Mirim, SP, em solo com textura areno-argilosa, onde alachlor a 2,15 kg, 2,58 kg e 3,01 kg/ha foi aplicado em mistura de tanque com diuron, a 1,00 kg/ha ou com cyanazine a 1,00 kg/ha. Os herbicidas que compuseram as misturas foram empregados isoladamente, naquelas mesmas doses. Constaram do experimento ainda, duas testemunhas mantidas sem mato por meio de capinas e uma testemunha sem capina. Os 14 tratamentos foram distribuídos em blocos ao acaso, com quatro repetições. Foram realizadas observações visuais de infestação de mato aos 14, 31,... |

| Trees, shrubs, lianas or rarely herbs, often with milky or viscid sap. Leaves opposite or sometimes verticillate or alternate, simple and always entire, penninerved. Stipules minute or mostly wanting. Flowers actinomorphic, hermaphrodite, arranged in racemose or cymose inflorescences or solitary. Calyx gamosepalous, 5-lobed, imbricate, often bearing glands (squamellae) within. Corolla gamepetalous, usually salver-shaped or funnelform, the tube occasionally bearing more or less conspicuous faucal appendages within (corona), the limb 5-parted, the lobes usually contorted in aestivation. Stamens (4—)5, inserted in the corolla-tube, alternating with the corolla-lobes; filaments usually short; anthers 4-celled, introrse, often sagittate and apiculate with the... |

| Em um latossolo, com teor de P disponível entre baixo e médio foi instalado um ensaio destinado a comparar a eficiência de um fosfato natural parcialmente acidulado (FAPS) com a do super simples (SS) e a do fosfato de Araxá (FA) original, na cultura da cana-de-açúcar (cana-planta). Os dados obtidos mostraram que: (1) o FAPS deu uma produção que não diferiu estatisticamente da obtida com o SS, sendo superior ao FA como fonte de P2O5; (2) os dados de diagnose foliar sugerem que o FAPS e o SS funcionam como fonte de P e de S; (3) o teor de açúcares redutores no caldo aumentou em consequência da adubação fosfatada; (4) o FAPS, na dose mais alta, elevou o teor de sacarose do caldo. |

| The columellar muscle system consists anteriorly of a high number of longitudinal branches surrounding a hydrocoel, which forms higher up two lateral, one ventral and four smaller dorsal bundles. These bundles enter the muscular envelope of head and nuchal region, which is formed out of the wing-wall muscles. The two lateral bundles proceed farest apically to insert on the buccal appendages; the four dorsal fibres fuse with the walls of buccal organs and oesophagus, while the ventral muscles run into the posterior and lateral footlobes. The wings are attached to the body by an extra right and left muscle neither derived from the columellar nor from the wing-wall muscle system. So the posterior and lateral footparts are mesopodal, the wings epipodal and the... |

| Lianas or sometimes herbs, shrubs or trees. Leaves alternate, simple, often cordate or reniform, entire to deeply lobed. Stipules wanting. Flowers solitary or in axillary fascicles or corymbs, actinomorphic or zygomorphic, hermaphrodite. Perianth simple, coloured, united and variously 3-lobed, rarely with 3 rudimentary petals. Stamens 5, 6, 12 or ∞, free or connate to the style. Ovary inferior or half-inferior, mostly 4—6-locular, sometimes nearly apocarpous. Ovary numerous, anatropous, on axile placentas. Fruit a septicidal capsule. Seeds with endosperm and small embryo. About 600 species in 7 genera mostly in the tropics and subtropics, especially in South America; only a few species in the temperate regions. |

| Data are given on the identification, biology, ecology, hosts, geographical distribution, control, and other aspects of the myiasis-producing flies in the Neotropical Region. The bibliography contains almost 2400 references, mainly related to Cochliomyia (ca. 1170 references), Cuterebridae (with the exception of Dematobia hominis (over 390 references), and to Dermatobia hominis (over 520 references). For Cuterebridae and Cochliomyia the bibliography covers the Américas; for ali other groups it is restricted to the Neotropics. |
