Biotic factors are more important than abiotic factors in regulating the abundance of Plutella xylostella L., in Southern Brazil

Disentangling factors limiting diamondback moth, Plutella xylostella (L.), spatio‐temporal population abundance: A tool for pest forecasting

“…However, despite the continuous availability of food sources throughout the year in some areas, P. xylostella showed a clear seasonality (Figures and ), in keeping with previous population surveillance studies (Chuang et al, ; Kfir, ; Mosiane et al, ; Nofemela, ). High populations were restricted between July and December (spilling into January), coincident with the periods of high temperatures, low RH and high availability of the host plant in Botswana, synonymous to similar other work (Kfir, ; Marchioro & Foerster, ; ). In addition, differences in diamondback moth populations across different farming regions are likely influenced by regional differences in abiotic factors, particularly temperature and relative humidity (Tonnang et al, ).…”

“…Furthermore, Marchioro and Foerster () attributed differential moth abundance in space to variations in rainfall patterns. Moreover, P. xylostella populations may vary spatio‐temporally owing to prevailing abiotic microclimatic variations and differential qualitative and quantitative resource availability (Kahuthia‐Gathu, ; Mosiane et al, ; Marchioro & Foerster ). The non‐availability of the host plants also negatively affected P. xylostella moth abundance.…”

“…Статус экономически значимого вредителя имеет капустная моль в тропических регионах мира -Индии, Базилии, Малайзии, Сенегале (Uthamasamy et al, 2011;Sow et al, 2013;Mohammad et al, 2014;Marchioro, Foerster, 2016). Таким образом, по литературным данным и результатам собственных исследований, проведенных в условиях Сибири, наблюдается увеличение численности по сезонам и количества лет с массовым размножением P. xylostella, и как следствие этого усиление ее вредоносности (Штерншис и др.…”

ESTADO DEL MIP DE Plutella xylostella (L.) (LEPIDOPTERA: PLUTELLIDAE) EN ARGENTINA

“…Son fundamentales los estudios de los factores que afectan la dinámica de la población para el desarrollo de estrategias de manejo para controlar P. xylostella (33). Estos autores, en trabajos posteriores (34) concluyeron que ni la temperatura y ni las precipitaciones registradas durante los experimentos de campo influyeron en la abundancia de la plaga. Sin embargo, para Bhagat et al (7) la gravedad de la incidencia de la polilla de las coles está muy influenciada por las condiciones climáticas predominantes que varían de región a región.…”
