“…Therefore, knowing the genetic resources of the selection candidates and using the tools of computer science help in this process (Khan, Matos, & Lima, 2009); it is not enough to have knowledge of the individuals, being also necessary to know the environmental variables that can affect their performance. Schafaschek, Hickel, Pereira, Oliveira, and Toledo (2016) found that local queens presented better performance for honey storage than queens introduced from other regions, possibly because queens introduced from other regions were brought virgin and were not acclimated to the environment, which ultimately affected their productive performance.…”

The objective of this research was to evaluate royal jelly production from Africanized honeybee queens of different lineages (lineage selected for honey production, lineage selected for royal jelly production and unselected) produced by single and double grafting and to compare royal jelly production among their offspring. Data were tested by double factorial analysis of variance and the means were compared by Tukey test at 5%. The parameters evaluated were: queen weight at emergence, percentage of larvae acceptance in the upper and lower bars, royal jelly per cup (mg) and royal jelly per colony/collection (g). Queens selected for honey presented greater weight at emergence, while the unselected queens were the lightest. Double grafting was better than simple grafting, since the queens were born 2.38% heavier. There was no difference (p > 0.05) in relation to royal jelly production according to neither the lineage nor even comparing the method by which the queens were produced. The cost of labor to produce queens by double grafting was much higher, as by the simple grafting about 170% more queens were born. The potential of Africanized honeybees with adequate production management and favorable environmental conditions favors the production of royal jelly.

“…The results corroborate with Faquinello et al (2011) who found that superior genotypes can express themselves differently depending on the production system to which they are submitted. Schafaschek et al (2016) also found that queens from different regions had their development influenced by the adopted management and local climatic variables, with advantage to the adapted local queens. Therefore, it is recommended the adoption of different management for colonies with queen from other regions.…”

“…The loss of many colonies in the winter of 2013, can be explained by a severe winter occurred, including the occurrence of snow, that is uncommon in the region. The establishment of the colonies with queens from other regions may have been difficult because an influence of climatic variables compared of the colonies with local queens, as verified by Schafaschek et al (2016). The introduction of the queen so late December to April, may have been difficult the initial development of this colonies because a shortage of flowering in this period in the region.…”

The hygienic behavior and variables related to the varroa mite in Apis mellifera colonies, with queens of different origins, were evaluated from October 2013 to June 2014. Queens from the selection program of the Maringá State University (Maringá / PR), from a beekeeper/ producer of Santa Terezinha/ SC and unselected queens, randomly selected in an experimental apiary (Irineópolis / SC) were evaluated. Colonies with queens of Maringá presented an increase in the invasion rate and total reproduction of varroa as there was reduction of hygienic behavior. This group presented a reduction in the effective reproduction of the mite, with a mean of 2.3 fertile offspring. Colonies with queens of Santa Terezinha presented an increase in the invasion rate due to the reduction of hygienic behavior, but in a less marked manner, since this characteristic remained stable, with an average of 92.0%. The total and effective reproduction of the mite for this group was 1.7 and 0.9 of total and fertile offspring, respectively. Colonies with queens of Irineópolis showed the lowest hygienic behavior (78.0%) and the highest total (12.6) and effective (5.3) reproduction of the mite. The use of selected queens, with hygienic behavior, interferes with the varroa population dynamics, contributing to the reduction of the invasion and total and effective reproduction rates of the mite.

“…No Brasil, o ácaro Varroa foi detectado pela primeira vez no ano de 1978 (ALVES; FLECHTMANN; ROSA, 1978), e embora as abelhas africanizadas apresentem resistência à patologia, nos últimos anos tem-se despertado preocupação quanto o aumento na taxa de reprodução do ácaro em células de abelhas operárias, quase o dobro quando comparado com a taxa de reprodução no período inicial de surgimento da doença no país. Este aumento significativo pode estar relacionado a mudanças genéticas entre os haplótipos de ácaros encontrados no território nacional (CARNEIRO et al, 2007;GARRIDO et al, 2003;WIESE;SALOMÉ, 2020), e pela ação de mudanças climáticas, fatores A varroatose está presente em todas as regiões do Brasil (GEHRKE;PUKER, 2020;MOREIRA et al, 2017;BARRETO, 2013;PINTO et al, 2015;SCHAFASCHEK et al, 2016), acometendo as abelhas africanizadas, porém, ao contrário do que acontece em outros países, os danos à apicultura brasileira causados por este ácaro ainda são toleráveis (CALDERÓN et al, 2010), pois estas espécies de abelhas desenvolveram rapidamente mecanismo de resistência, denominado de comportamento higiênico de remoção de crias doentes/infestadas (CORREIA-OLIVEIRA et al, 2018). Para mensurar os níveis de infestações nas crias, retirou-se de cada colônia amostral um pedaço de favo contendo crias operculadas (pupas).…”

O Varroa destructor é o ectoparasita mais prejudicial às abelhas Apis mellifera, ele pode parasitar tanto abelhas adultas como crias, se alimentando da hemolinfa e dos tecidos adiposos desses insetos, introduzindo no processo, diversos vírus que chegam a causar o declínio total da colônia. A dinâmica populacional deste ácaro em abelhas africanizadas no alto sertão paraibano ainda é pouco estudada e conhecida pelos apicultores da região. Portanto, objetivou-se com este trabalho, avaliar os índices de infestação desse ácaro em colônias de abelhas africanizadas nos municípios de Aparecida – PB e São Francisco – PB, a fim de descrever sua dinâmica populacional nas localidades. Para isso, entre os meses de março e maio de 2020, foram realizadas três coletas de aproximadamente 300 espécimes de abelhas adultas retiradas dos quadros centrais de ninho, e cerca de 100 crias operculadas que foram mantidas em recipientes e levadas ao Laboratório de Entomologia para calcular as porcentagens de infestação nos dois estágios biológicos. Os resultados demonstraram ocorrência de Varroa destructor em todas as colônias analisadas nos dois municípios, no entanto, a dinâmica populacional do ácaro variou entre essas localidades, em Aparecida – PB a maioria das colônias tiveram taxa de infestação de 0,1-2% em ambos os estágios biológicos analisados, já em São Francisco, o maior percentual de colônias tiveram infestação nas suas crias entre 12,1->15%, e nas adultas de 2,1-4%. Os índices de infestação de Varroa nas crias de abelhas africanizadas em São Francisco – PB indicam grau moderado de varroatose, necessitando de intervenção pelos apicultores.
