Some biological parameters and colonization of Aleurodicus cocois on dwarf-cashew
The aim of this study was to investigate the biology and colonization of A. cocois on dwarf-cashew seedlings. Levels of colonization were scored on a scale ranging from 0 to 4, and biology was established by evaluation of oviposition and reproductive parameters. Egg incubation time was 7.1 ± 0.88 da...

| Sumario: | The aim of this study was to investigate the biology and colonization of A. cocois on dwarf-cashew seedlings. Levels of colonization were scored on a scale ranging from 0 to 4, and biology was established by evaluation of oviposition and reproductive parameters. Egg incubation time was 7.1 ± 0.88 days, first, second, third and fourth instar nymph phases lasted 5.9 ± 1.54, 6.8 ± 2.02, 5.2 ± 1.93 and 8.1 ± 2.69 days, respectively, egg-to-adult development took 33.1 ± 4.06 days, adult longevity was 14.3 ± 5.52 days and female fecundity was 43 ± 8.5 eggs female-1. Peak colonization occurs within 190 days. |
