Varroa destructor has been in Brazil for more than 30 years, but no mortality of honeybee colonies due to this mite recorded. Africanized bee infestation rates attained by varroa have low, without causing measurable damage Brazilian apiculture. The low reproductive ability parasite worker brood cells considered an important factor maintaining the host-parasite equilibrium. Nevertheless, possible substitution haplotype that occurred recently could affected population Brazil. females was...
Varroa destrutor haplotypesshowed only the specific alleles of haplotype J, while in bees from Santa Catarina, these were found 2.8% samples.The high frequency individuals with Korean genetic material is probably to reason for current reproductive capacity mite V. destructor recorded Catarina.
The mite Varroa destructor is the main pest causing damage to apiculture worldwide. In Brazil and other parts of world, where bees African origin their hybrids predominate, can survive these mites without treatment. Studies have shown a correlation between various genotypes its fertility in different geographical regions. Information about genotype could be helpful understanding diverse effects relationships with regions world. DNA analysis by RAPD technique has permitted identification...
Varroa destructor mite causes mortality of Apis mellifera bees throughout the world. Its greatest damage to these colonies has been reported in European countries and North America. The impact is related climate bee race on each region which plague established. little africanized honeybees Brazil levels infestation are relatively small stable. reproductive ability females was evaluated pupae workers 17-18 days age, obtained from eight beehives for twelve months. average number offspring...
SummaryThe effective reproductive capacity of Varroa destructor in honey bee colonies is currently calculated on the basis number female deutonymphs found singly infested worker brood cells at 17–18 days (two to three before emerges). This calculation presumes that will reach adult stage by time ecloses. Some may not, however, phase and there also could be mortality. In order examine this possibility, we studied mite reproduction Africanized then selected eight which over 90% contained a...
Inseticidas carbamatos, como o carbaril, exercem efeitos tóxicos em animais por inibirem a atividade de B-esterases, tais acetilcolinesterase (AChE) e carboxilesterase (CbE). Carbamatos usados na agricultura podem atingir os ambientes aquáticos afetando organismos não-alvo, aquáticos. Anfíbios anuros são particularmente sensíveis aos agrotóxicos, apresentarem fase inicial vida totalmente aquática muitas vezes limitada próximos à agricultura. Variações temperatura da água importantes nas...
