Potential displacement of the native Tenuisvalvae notata by the invasive Cryptolaemus montrouzieri in South America suggested by differences in climate suitability

Abstract

Tenuisvalvae notata (Mulsant) (Coccinellidae) is a predatory ladybird beetle native to South America. It specializes in mealybugs prey (Pseudococcidae), but relatively little is known about its ecology. In contrast, the ladybird beetle Cryptolaemus montrouzieri Mulsant (Coccinellidae) is indigenous to Australia and has been introduced to many countries worldwide including Brazil for biological control of mealybugs. The potential impacts of these introductions to native coccinellids have rarely been considered. The software CLIMEX estimated the climate suitability for both species as reflected in the Ecoclimatic Index (EI). Much of South America, Africa, and Australia can be considered climatically suitable for both species, but in most cases, the climate is considerably more favorable for C. montrouzieri than T. notata, especially in South America. The CLIMEX model also suggests seasonal differences in growth conditions (e.g. rainfall and temperature) that could affect the phenology of both species. These models suggest that few locations in South America would be expected to provide T. notata climatic refugia from C. montrouzieri. Although other ecological factors will also be important, such as prey availability, this analysis suggests a strong potential for displacement of a native coccinellid throughout most of its range as a consequence of the invasion by an alien competitor.

Cannibalism and intraguild predation between endemic and introduced coccidophagous lady beetles (Coleoptera: Coccinellidae)

“…2013; Lima & Santos 2018). Based on the thermal requirements of T. notata and C. montrouzieri , and the climatic conditions in different regions of Brazil, both species could occur in the same places (Ferreira et al 2021), as reported by Peronti et al . (2016); in a field survey in the State of São Paulo, Brazil, both lady beetle species were found in the same area.…”

“…2020) and used the CLIMEX model to estimate the global geographic distribution of T. notata and C. montrouzieri (Ferreira et al . 2021) based on climatic conditions and thermal requirements of both predators. We found that both studied species could occur in tropical and subtropical areas, in the same habitat, and prey upon the same prey.…”

“…Oliveira et al (2021) estimated that in warmer areas, the introduced species have a higher number of descendants per year than the native species. Prior to this work, our research group has investigated the thermal requirements and predation potential of T. notata (Ferreira et al 2020) and used the CLIMEX model to estimate the global geographic distribution of T. notata and C. montrouzieri (Ferreira et al 2021) based on climatic conditions and thermal requirements of both predators. We found that both studied species could occur in tropical and subtropical areas, in the same habitat, and prey upon the same prey.…”

“…Also, the exotic lady beetle species Cryptolaemus montrouzieri Mulsant, 1853 was introduced in Brazil to control Planococcus citri (Risso 1813) in citrus orchards (Sanches & Carvalho 2010) and more recently used to control the hibiscus mealybug Maconellicoccus hirsutus (Green, 1908) (Culik et al 2013;Lima & Santos 2018). Based on the thermal requirements of T. notata and C. montrouzieri, and the climatic conditions in different regions of Brazil, both species could occur in the same places (Ferreira et al 2021), as reported by Peronti et al (2016); in a field survey in the State of São Paulo, Brazil, both lady beetle species were found in the same area. Hence, they could compete for resources in the same habitat and intraguild predation might happen when prey is limited.…”

“…Las especies exóticas representan una amenaza para la estructura, función e integridad de los ecosistemas (Ferreira et al, 2021), contribuyen a la extinción de algunas especies (Rocha et al, 2021) e introducen agentes infecciosos al ambiente colonizado (Hernandez-Colina et al, 2021). La paloma de collar turca (STRDEC, Streptopelia decaocto) es una especie invasora con amplia distribución en Norteamérica (eBird, 2021).…”
