Life table of the red spider mite Tetranychus bastosi (Acari: Tetranychidae) on different host plants

Abstract

Tetranychus bastosi Tuttle, Baker and Sales was described from Ceará state, northeastern Brazil. It has so far been reported from 25 plant species, among which cassava (Manihot esculenta Crants), common bean (Phaseolus vulgaris L.) and papaya (Carica papaya L). Although there is no information about its impact on crop yield, high population levels have been observed on some crops, leading to suppose that damage might occur in some occasions. In this study, fertility life table parameters were calculated for T. bastosi on cassava, common bean and papaya at 25 ± 2 °C, 70 ± 5% RH and photoperiod of 12/12 h. The best performance of T. bastosi occurred on C. papaya and P. vulgaris, on which the intrinsic rate of population increase reached 0.184 and 0.183 female/female/day, respectively. These results agree with the most common occurrence of this mite on papaya and on common bean than on cassava.

The Resistance of Seven Host Plants to Tetranychus merganser Boudreaux (Acari: Tetranychidae)

“…(Asteraceae), P. lunatus (Fabaceae) and P. vulgaris (Fabaceae)), and found that T. urticae Koch lays more eggs on fabaceous plants. Further, De Lima et al [27] documented that the total fecundity and daily oviposition rate of T. bastosi Tuttle, Baker & Sales were higher in C. papaya (50.6 ± 4.4), than on P. vulgaris (36.1 ± 2.5) and Manihot esculenta (Euphorbiaceae) (26.5 ± 2.2). Chacón-Hernández et al [11] reported that T. merganser oviposited more on fabaceous plants than on solonaceous plants.…”

“…It is likely that T. merganser females lay a higher numbers of eggs on C. papaya than on other plant species, this is caused by differences in nutrient contents, morphological characteristics and different secondary metabolites found in different plant families. [26][27][28][29][30].…”

“…Chacón-Hernández et al [11] reported values of r of T. merganser on fabaceous (0.4237) and solanaceous (0.6014) plants, lower than those obtained in this present study (0.7133 and 0.5568, respectively). De Lima et al [27] found that T. bastosi had the best reproduction rates on both caricaceous and fabaceous plants than on euphorbiaceous plants. There are a variety of factors influencing the population growth parameters of tetraniquids, e.g., host plant species, quality of the host plant, strain of mite, environmental factors, plant breeding method and data analysis method [14,26,27,29,33].…”

Avicultura de postura em Pernambuco: Uma análise pela cadeia de valor

“…Uma preocupação significativa está relacionada ao ácaro-praga Tetranychus bastosi Tutler, Baker & Sales, o qual tem sido registrado em plantios em diferentes regiões do Brasil, e é considerado uma das principais pragas da cultura no mundo (CRUZ et al ,2012;PEDRO-NETO et al, 2013;BARROS, 2013;LOFEGO et al, 2013;LIMA et al, 2017;CAÑARTE et al, 2020). Característico por produzir teias, T. bastosi se alimenta do conteúdo celular extravasado das células perfuradas pelas quelíceras em forma de estiletes, e ataca folhas velhas, provocando manchas branco-acinzentadas e prateadas na face abaxial da lâmina, além de ondulações por todo o limbo e encarquilhamento (DRUMMONT et al, 1984;SANTOS et al, 2006;SATURNINO et al, 2005;BELTRÃO et al, 2007;GABRIEL, 2008; FRANCO; GABRIEL, 2008; DE MORAES; FLECHTMANN; SANTOS et al, 2008).…”
