Interspecific Mating Effects on Locomotor Activity Rhythms and Refractoriness of Aedes albopictus (Diptera: Culicidae) Females

Abstract: This study tests the hypotheses that the locomotor activity of Ae. albopictus females is not significantly altered by the presence of accessory gland (AG) extracts from conspecific and heterospecific males, and that Ae. albopictus females remain receptive to mating with conspecific males even after receiving AG of Ae. aegypti males. Virgin Ae. albopictus females were injected with saline (control group), AG extracts of Ae. aegypti males (aegMAG) or AG extracts of Ae. albopictus males (albMAG). Locomotor activi… Show more

“…From a quantitative perspective, insemination modifies the strength of A. coluzzii ’s female activity in both LD and DD; this effect is apparent from the decreased levels of the peaks that occur shortly after lights off and lights on under LD, the increase in overall night activity in both LD and DD, a sustained and constant level of activity at night for at least 6 days, and, lastly, from the delayed onset of activity under both light regimens, this delay reaching almost half an hour in some individuals under DD. The modification of activity strength by insemination has been previously observed in Anopheles [ 9 , 30 ] and in other mosquito species [ 75 ]. For example, two closely related taxa of the Culex pipiens complex, Cx p. pallens and Cx p. molestus , both display strengthened nightly activity after insemination, and in Cx p. molestus daily activity is suppressed so that this taxon becomes purely nocturnal [ 76 , 77 ].…”

“…O sistema de análise de atividade que foi utilizado é o Drosophila Activity Monitor (Trikinetics), que foi desenvolvido inicialmente para estudos com moscas do gênero Drosophila, mas que vem se mostrando muito eficiente também nos estudos de ritmos circadianos de mosquitos (LIMA-CAMARA et al, 2013;FEITOZA et al, 2020). Assim, os mosquitos foram colocados individualmente em tubos de vidro, com 10 mm de diâmetro e 7 cm de comprimento, tendo, em uma das extremidades, um pequeno algodão embebido com solução açucarada 15%.…”

“…Os dados foram organizados em planilhas do Excel e normalizados por transformação logarítmica (Log N+1), para deixar a distribuição mais restrita, considerar os valores iguais a zero e evitar que os valores muito altos ou muito baixos mascarassem os resultados (PADILHA et al, 2018;FEITOZA et al, 2020). Para as análises estatísticas, também foram utilizados os valores de atividade locomotora transformados em Log (N+1).…”
