Giant Salvinia

The salvinia weevil, Cyrtobagous salviniae (Calder & Sands) (Coleoptera: Curculionidae) (Figure 1), is a subaquatic (underwater) herbivorous insect native to Brazil (Calder and Sands 1985). This insect feeds on the invasive aquatic plants Salvinia molesta D. S. Mitchell and Salvinia minima (Baker). This insect is an effective classical biological control agent used in several countries to control the invasive giant salvinia, Salvinia molesta (D. S. Mitch). Feeding by Cyrtobagous salviniae larvae and adults kills its invasive host plants and restores recreational, agricultural, and ecosystem functions in aquatic systems. In the United states, the insect has been credited for controlling Salvinia minima in Florida (Jacono et al. 2001) and causing the decline of Salvinia molesta in Texas and Louisiana (Tipping et al. 2008).

Penelitian dilaksanakan selama 28 hari di Pusat Penelitian Lingkungan Hidup Institut Pertanian Bogor (PPLH-IPB). Perlakuan terdiri dari ikan kecil (panjang total 7-12 cm) dengan kepadatan 5 dan 10 ikan/akuarium dan ikan besar (panjang total 21-24 cm) dengan kepadatan 2 dan 4 ekor/akuarium. Kiambang (Salvinia molesta) dengan biomassa awal 100 gram dimasukkan pada setiap akuarium untuk menutupi permukaan wadah sebesar 75%. Hasil penelitian menunjukkan bahwa bobot tertinggi biomassa giant salvinia yang dikonsumsi sebesar 164,13±62,12 gram terjadi pada perlakuan grass carp ukuran besar dengan padat tebar 4 ekor, yang diikuti dengan pertambahan bobot ikan rata-rata sebesar 6,63±6,51 gram.

Adult Weevil

In 2012, a giant salvinia (Salvinia molesta Mitchell) biological control project was initiated in Louisiana. Although similar quantities of salvinia weevils (Cyrtobagous salviniae Calder and Sands) were released at all sites, weevil densities were highly variable among sites. Additionally, signs of plant nitrogen depletion (yellowing plants) were observed at some sites. Because it is well known that plant nutrition can affect the success of a biocontrol agent because of slowed development and/or reduced fecundity, the correlation between giant salvinia nitrogen content and Salvinia weevil density was investigated during the growing seasons of the second and fourth years. During 2013, weevils were reintroduced to sites, and the magnitude of adult weevil density increase varied by site. Giant salvinia nitrogen content varied among sites and sampling dates. Upper Big Break plants had greater nitrogen than all other sites during 75% of sampling dates. Additionally, adult and larval densities were significantly correlated to plant nitrogen content. During 2015, trends were less distinct and weevil densities and nitrogen content varied based on the interaction between sampling date and site, but a significant correlation was not detected. Results from 1-yr of a 2-yr study confirmed published reports of the importance of plant nitrogen content to salvinia weevil productivity. Additional studies are warranted to evaluate and understand the role of nitrogen at giant salvinia biocontrol field sites.

AbstractImmense stands of bald cypress [Taxodium distichum (L.) Rich.] make it difficult for herbicide applicators to access the free-floating fern giant salvinia (Salvinia molesta Mitchell), which can be found growing under the canopy of the trees. The difficulty of accessing these areas, as well as avoiding direct contact of herbicides with tree foliage, provides a substantial amount of nonmanaged plant material capable of rapidly reinfesting treated sites, thus making management efforts null and void. Herbicide application during the winter, when bald cypress sheds its leaves, may be an ideal time to manage S. molesta and minimize negative impacts on the nontarget tree. Therefore, the herbicides diquat, glyphosate, flumioxazin, and glyphosate+diquat were evaluated at one of the three application timings (December, January, or February) against S. molesta and immature bald cypress during the winter. All herbicide treatments, except diquat applied in February of year 1, reduced S. molesta biomass 40% to 100%. In addition, flumioxazin applications during December, January, and February provided ≥70% S. molesta control with little or no negative impacts to bald cypress health. A treatment by timing interaction revealed that trees exposed to flumioxazin did not result in a significant decrease in average leaf length when compared with reference trees 20 wk after bud break at any of the three application timings. In addition, bald cypress exposed to flumioxazin produced the highest probability of a refoliation pattern equivalent to the nontreated reference trees. Although complete tree mortality was not documented in either study, delayed and abnormal leaf formation, reduced leaf length, irregular canopy formation, or no negative effects were observed among herbicide-treated bald cypress. This research suggests that winter herbicide applications over the top of dormant bald cypress may be a practical management technique for controlling severe infestations of S. molesta.
