“…However, many factors affect establishment and success of Lepidoptera in biological control programs. Dray et al (2001) discuss these factors in their unsuccessful attempts to establish a Spodoptera pecticornis Hampson (Lepidoptera: Noctuidae) against waterlettuce (Pistia stratiotes L.) in Florida. The Callopistria spp., also belonging to Noctuidae, may face similar challenges.…”

Lygodium microphyllum, Old World climbing fern, is native to the wet tropics and subtropics of the Old World and an invasive weed in southern Florida. Exploration for natural enemies of this weed was conducted between 1997 and 2002 in Australia, China, India, Indonesia, Japan, Malaysia, New Caledonia, Singapore, Taiwan, Thailand, and Vietnam. Two species of mites and 20 insect species were collected. The eriophyid mite, Floracarus perrepae Knihinicki and Boczek, was the most widely distributed and appeared to cause significant damage to the plant over time. Several unique geographical genotypes of F. perrepae were identified. Other promising candidates for further research are the musotimine pyralid species, Neomusotima conspurcatalis Warren, Cataclysta camptozonale Hampson, Cataclysta sp. 2, and Musotima sp., all leaf-feeders, as well as the stem-borer Ambia sp. All of the herbivores collected, except the eriophyid, typically occurred at low field densities. The pyralid species may reach high densities and cause great damage in Florida in the absence of their co-evolved natural enemies. The mite F. perrepae shows the greatest potential for biological control based on field surveys and initial laboratory observations; however, future studies must identify mite genotypes that are best adapted to the invasive Florida form of the fern.

“…Other factors may be influencing the effectiveness of C. salviniae as a herbivore, possibly including nutrient limiting and interspecies interactions with other arthropods ). The red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) has been known to impact populations of C. salviniae and prey on other biological control agents for aquatic plants (Dray et al 2001;Cuda et al 2004;Parys & Johnson 2012). Other reports of predation on C. salviniae include Hydrochus sp.…”

“…Biological control, being effective and having a low cost and relatively high environmental safety, has been widely accepted [6]. However, many natural enemies have recently been verified as being inefficient in biologically controlling invasive plants in the invaded communities [7], [8], even though the host-specific agents were efficient in pot experiments. Thus, exploring the mechanism underlying this phenomenon would be important and useful in developing future biological controls of invasive species.…”

Interactive Effect of Herbivory and Competition on the Invasive Plant Mikania micrantha

A considerable number of host-specific biological control agents fail to control invasive plants in the field, and exploring the mechanism underlying this phenomenon is important and helpful for the management of invasive plants. Herbivory and competition are two of the most common biotic stressors encountered by invasive plants in their recipient communities. We predicted that the antagonistic interactive effect between herbivory and competition would weaken the effect of herbivory on invasive plants and result in the failure of herbivory to control invasive plants. To examine this prediction, thus, we conducted an experiment in which both invasive Mikania micrantha and native Coix lacryma-job i were grown together and subjected to herbivory-mimicking defoliation. Both defoliation and competition had significantly negative effects on the growth of the invader. However, the negative effect of 75% respective defoliation on the above- and below-ground biomass of Mikania micrantha was alleviated by presence of Coix lacryma-jobi. The negative effect of competition on the above- and below-ground biomass was equally compensated at 25%, 50% and 100% defoliation and overcompensated at 75% defoliation. The interactive effect was antagonistic and dependent on the defoliation intensity, with the maximum effect at 75% defoliation. The antagonistic interaction between defoliation and competition appears to be able to release the invader from competition, thus facilitating the invasiveness of Mikania, a situation that might make herbivory fail to inhibit the growth of invasive Mikania in the invaded community.
