Última Varroa destructor mite in Africanized honeybee colonies Apis mellifera L. under royal jelly or honey production Animal Sciences Santos, Pedro da Rosa; Wielewski, Priscila; Halak, Andre Luiz; Faquinello, Patrícia; Toledo, Vagner de Alencar Arnaut de.  This study evaluated the level of invasion of Varroa mite into worker brood cells, the infestation rate on adult worker honeybees, total and effective reproduction rates of the mite in Africanized honeybee colonies under royal jelly or honey production. Invasion and infestation rates were not statistically different between honeybee colonies producing honey or royal jelly and the averages for these parameters were 5.79 and 8.54%, respectively. Colonies producing honey presented a higher (p < 0.05) total and effective reproduction of Varroa than colonies producing royal jelly. There was a negative correlation between levels of invasion and infestation with minimum external temperature, relative humidity and rainfall. The variables month and season...

La varroasis es considerada la más seria enfermedad parasitaria de las abejas (Apis mellifera L.) y es provocada por el ácaro Varroa destructor Anderson &amp; Truemann. Una gran cantidad de productos han sido probados para el control de esta enfermedad parasitaria. Actualmente se han generado razas resistentes, problemas de contaminación de la miel y de otros productos de la colmena, debido al uso indiscriminado y reiterado de algunos productos contra este ácaro. La tendencia actual es el uso de productos naturales como parte de una estrategia de control integrado. Esta investigación tuvo como objetivo evaluar los efectos de los aceites esenciales extraídos de Lavandula officinalis Chaix y Laurelia sempervirens (Ruiz et Pav.) Tul. sobre el ácaro Varroa...

Ano: 2004 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0365-28072004000300003 Evaluation of Metarhizium anisopliae var. anisopliae Qu-M845 Isolate to Control Varroa destructor (Acari: Varroidae) in Laboratory and Field Trials Chilean J. Agric. Res. Rodríguez,Marta; Gerding,Marcos; France,Andrés; Ceballos,Ricardo. The effectiveness of the Metarhizium anisopliae (Metschinkoff) Qu-M845 isolate was evaluated in laboratory and field trials. It was previously selected for thermal resistance (at 30 and 35 ºC) and pathogenicity on Varroa destructor (Anderson and Trueman). In the laboratory, the first evaluations were carried out by spraying and increasing the concentration from zero to 10(8) conidia mL-1 on varroa adults. Lethal concentrations required for 50 and 90% mite mortality (LC50 and LC90) were 3.8 x 10(5) and 8 x 10(7) conidia mL-1, respectively (&#967;2 = 2.03). In the autumn field trials, three application methods (doses of 5 x 10(10) conidia per hive) were evaluated. The treatments were: a) conidia stamped on filter paper, located on every second frame...

Ano: 2009 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-58392009000400009 Selection of Entomopathogenic Fungi to Control Varroa destructor (Acari: Varroidae) Chilean J. Agric. Res. Rodríguez,Marta; Gerding,Marcos; France,Andrés. The aim of this work was select entomopathogenic fungi tolerant to temperatures inside the brood area of honey bees (Apis mellifera) for to control Varroa destructor. For this purpose, 50 Beauveria bassiana (Balsamo) Vuillemin and 48 Metarhizium anisopliae (Metschn.) Sorokin isolates were evaluated at 30 and 35 ºC. For each isolate, colony discs of 5 mm with mycelium were placed in the center of a Petri dish with Sabouraud dextrose agar (SDA) medium. The dishes were incubated at 30 and 35 °C, without light. Radial growth of each colony was measured daily. All the B. bassiana and M. anisopliae isolates presented a lineal growth rate at a temperature of 30 ºC. However, at 35 ºC, most of the isolates did not grow, except three B. bassiana and 14 M. anisopliae...
