ABSTRACT We compared the cold tolerance of three populations of the salvinia weevil, Cyrtobagous salviniae. When exposed to 0°C, lethal time to kill 90% of adults from the Bayou Nicholas population was greater than the Houma and Natchitoches populations. This weevil exhibited phenotypic plasticity which could be used in mass rearing.

Abstract Salvinia molesta D.S. Mitchell (Salviniaceae) (giant salvinia), a floating aquatic fern of Brazilian origin, has been dispersed to much of the tropical and subtropical parts of the world



Low temperature reproduction of Cyrtobagous salviniae: good news for biological control of salvinia in a temperate climate.

Field trials usingSalvinia weevil in the temperate Hawkesbury-Nepean catchment New South Wales, Australia, show that biological control of salvinia in temperate regions is possible at river, creek, and dam sites.

Biological control of giant salvinia (Salvinia molesta) in a temperate region: cold tolerance and low temperature oviposition of Cyrtobagous salviniae

It is suggested that introduction of cold tolerant strains of C. salviniae could increase its effectiveness in temperate regions of the US.

Repeated Cold Exposure Effects on Mortality and Feeding Activity of the Salvinia Weevil, Cyrtobagous salviniae (Coleoptera: Curculionidae)

The effects of repeated cold exposure (RCE) on the overwintering mortality and feeding rate of adult C. salviniae and the feeding activity of adult weevils surviving RCE declined following exposure to 4 and 6 cycles of RCE.

Salvinia molesta D. S. Mitchell (Giant Salvinia) in the United States: A Review of Species Ecology and Approaches to Management

Abstract : Over the past 70 years, the free-floating aquatic fern Salvinia molesta D. S. Mitchell (giant salvinia) has spread from its native range in Brazil to many tropical and subtropical regions.

The biological control of aquatic weeds in South Africa: Current status and future challenges

A review of the biological control programme on waterweeds in South Africa shows significant reductions in the extent of invasions, and a return on biodiversity and socio-economic benefits through the use of this method.

What is phenotypic plasticity and why is it important

Phenotypic plasticity is important because it is an encompassing model to understand life on earth, it can increase fitness, generate novelity, and facilitate evolution, it structures ecological communities, and it has numerous practical applications.
