This study aimed to evaluate the effects of pesticides, used in the organic system, on Apis mellifera under laboratory conditions. Four multiple (0.25x, 0.5x, 1x and 2x) concentrations as recommended by they manufacturers of the following products: Rotenat CE®, Pironat®, Biopirol 7M®, Organic neem®, Natuneem® and lime sulfur were tested by topical application and ingestion. Of all the products and concentrations tested, only the lime sulfur (5000 ml 100L-1 and 10000 mL 100L-1 of water) by ingestion, and Rotenat CE® (1200ml 100L-1 of water) on topical application were considered slightly harmful for A. mellifera, as the classification of IOBC/WPRS for the laboratory tests. |

ABSTRACT: The innate immune system of honeybees mainly consists in antimicrobial peptides, cellular immunity and melanisation. In order to investigate the immune response of honeybees to immune stressors, three stress degrees were tested. Newly emerged bees naturally DWV-infected were collected from a Varroa mite-free apiary and divided into three experimental groups: naturally DWV infected bees, PBS injected bees, and artificially DWV super infected bees. Phenoloxidase activity and haemolymph cellular subtype count were investigated. Phenoloxidase activity was highest (P<0.05) in DWV-superinfected bees, and the haemocyte population differed within the three observed groups. Although, immune responses following DWV infection have still not been... |

The presence of bees (Apis mellifera L.) in urban areas has increased in recent years due to environmental disturbances caused by humans. Bee migration to cities may provoke serious accidents, since some people present allergic reactions to their venoms. In Rio Claro city, São Paulo state, Brazil, the number of calls to the fire brigade for removal of bee swarms, and the number admissions in local hospitals due to bee stings were investigated during 2002 and 2003, and a correlation between these data and the average temperature, rainfall and relative humidity was found. The study period was divided into three phases according to the number of times that the fire brigade was called to remove swarms (263 times): January to July 2002 - 51 calls (19.39%);... |

The present study aimed to acquire knowledge regarding some aspects of the epidemiology and injuries provoked by honeybees and caterpillars in southern Santa Catarina State, Brazil. Epidemiological information concerning accidents with both animals was prospectively collected from the System of Injury Notification Information (SINAN) files of the Municipal Health Secretary of the Criciúma region, Brazil. Between 1994 and 2006, 203 cases of accidents were registered, 149 provoked by honeybees (73.39%) and 54 by caterpillars (26.61%). The majority of the victims (200 cases) presented full recovery, two cases presented sequelae after recovery, and only one death was recorded in a case involving honeybee injury. The high frequency of victim recovery suggests... |

The presence of Apis mellifera in places such as candy and soft drink factories, restaurants, and ice-cream shops has been a concern to many people. In the yellow passion-fruit crop, Apis mellifera is able to collect all anther pollen but has no active role in pollination. Honeybees also visit animal feeders with chopped sugar cane, preventing the cattle from eating. This work studied the effect of natural and synthetic substances as Apis mellifera repellents in vitro in the yellow passion-fruit crop and in confined beef cattle feeders. There was a repellent effect in vitro with the following substances in decreasing order: tobacco, rue, garlic, parsley, and century plant extracts; average effect was twenty-five minutes. For the yellow passion-fruit,... |

Africanized honeybees from five colonies were marked with P-32 and taken to an apple grove for a flight behavior study. The method used to determine the flight range was to put out an array of tagged trees in a cross pattern with the colonies arranged in the center point of a 0.8 ha test area. The tagged trees were located 10 meters apart in the 4 rows of 50 meters each, arranged according to the North, South, East, and West directions. Bees were collected while visiting the tagged tree flowers twice a day, during a ten-day period. The number of honeybees marked decreased in relation to the distance from the hives. Analysis of variance showed that a linear regression was highly significant to describe the process. Geographic directions did not affect the... |
