Biologia e tabela de vida de fertilidade da broca-do-morangueiro criada em dieta artificial

Abstract

Resumo -O objetivo deste trabalho foi determinar os parâmetros biológicos e a tabela de vida de fertilidade da broca-do-morangueiro (Lobiopa insularis) criada em dieta artificial à base de frutos de morangueiro, em condições de laboratório. A duração e a viabilidade média dos períodos embrionário, larval, pupal e ovo-adulto foram de: 4,1±1,5 dias e 80,6%; 22,2±5,0 dias e 60%; 10,8±2,3 dias e 90%; e 37,1±8,8 dias e 43,5%, respectivamente. Os períodos de pré-oviposição, oviposição e pós-oviposição foram de 96±18,9, 133±27,5 e 77±16,3 dias. A longevidade de machos (271±20,7 dias) foi menor do que a de fêmeas (318±14,9 dias). Há potencial de utilização de dieta artificial à base de morangos para a multiplicação da broca-do-morangueiro em laboratório.Termos para indexação: Fragaria x ananassa, Lobiopa insularis, Coleoptera, ecologia, Nitidulidae, Rosaceae. Biology and fertility life table of strawberry sap beetle reared on artificial dietAbstract -The objective of this work was to determine the biological parameters and fertility life table of the strawberry sap beetle (Lobiopa insularis) reared on artificial diet in laboratory conditions. The duration and the average viability of the embryonic, larval, pupal, and egg-to-adult periods were: 4.1±1.5 days and 80.6%; 22.2±5.0 days and 60%; 10.8±2.3 days and 90%; and 37.1±8.8 days and 43.5%, respectively. The pre-oviposition, oviposition, and post-oviposition periods were 96±18.9, 133±27.5, and 77±16.3 days. The longevity of males (271±20.7 days) was lower than that of females (318±14.9 days). There is potential for using artificial diet based on strawberries for the multiplication of the strawberry sap beetle in laboratory.

Life history traits and life table analysis of Lobiopa insularis (Coleoptera: Nitidulidae) fed on strawberry

“…Maximum adult longevity was 219 days for females and 211 for males. These values are lower than those observed by [ 35 ] for L . insularis fed on an artifitial diet: 306 days.…”

“…Survival of females ( Fig 1 ) and males were similar (Gehan-Wilcoxon test statistic = 0.17, p = 0.865). Survival from egg to adult (64.20%) was higher than that obtained by [ 35 ] (43.5%).…”

“…The number of eggs/female/day (18.1±3.74) was also higher in our study than [ 35 ], who reported a daily fecundity of 13.9±5.8 eggs/female/day. The pre-reproductive period was shorter than the reproductive and post-reproductive periods, which were significantly longer and more variable than the former ( Table 2 ).…”

Analyzing weight evolution in mice infected by Trypanosoma cruzi

“…According to Keele (2008), splines are segmented polynomial functions united by cutoff points known as "nodes", which are used for fitting a curve in a dataset. Spline functions have been widely used in the analysis of longitudinal data -for instance, in the fitting of lactation and growth curves, as seen in Caldeira (2011), Pinheiro et al (2013), Domingues, Gonçalves, Braz, & Pereira (2014), and Santos et al (2015). The literature provides several techniques to represent this fitting by parts, such as linear spline, cubic spline, Bspline, etc.…”

“…Females oviposit in the ground, and the larvae pupate within the first 10 cm (Cluigt et al 2007). The long life span of adults (up to seven months) and high reproductive output, indicate the presence of several overlapping generations (Bortoli et al 2014;Greco et al 2017).…”
