Biological Control of Purple LoosestrifeA case for using insects as control agents, after rigorous screening, and for integrating release strategies with research
P urple loosestrife (Lythrum salicaria L.) is an exotic wetland perennial responsible for the degradation of many prime wetland habitats throughout the temperate regions of the United States andExpand
Host Specificity and Environmental Impact of Two Leaf Beetles (Galerucella calmariensis and G. pusilla) for Biological Control of Purple Loosestrife (Lythrum salicaria)I
Evaluation of the potential environmental impact of the two leaf beetles showed that benefits of an introduction outweigh potential risks to winged lythrum or swamp loosestrife. Expand
Establishment of insect biological control agents from Europe against Lythrum salicaria in North America
Three European biological control agents of the exotic, wetland, perennial plant purple loosestrife, Lythrum salicaria L., were released in North America in 1992 and 1993 and successfully passed the most critical phase for establishment in NorthAmerica; production of the generation following release.

Developing a Sterile Insect Release Program for Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae): Effective Overflooding Ratios and Release-Recapture Field Studies
Results suggest that an overflooding ratio as low as 5:1 can effectively suppress C. cactorum in field cages and that releasing both genders together is more effective than releasing males only. Expand
Biology, host specificity tests, and risk assessment of the sawfly Heteroperreyia hubrichi, a potential biological control agent of Schinus terebinthifolius in Hawaii
A risk analysis was conducted toquantify the acceptability of non-targetspecies as host plants for H. hubrichi on the basis of the insect's performance atvarious stages in its life cycle, and it was found that the risk to this native plant relative to S. terebinthifolius was too high to request introduction of this insect into theHawaiian environment.

Host Specificity and Environmental Impact of the Weevil Hylobius transversovittatus, a Biological Control Agent of Purple Loosestrife (Lythrum salicaria)I
An environmental assessment of the potential effects of the release of the purple loosestrife borer in North America indicated that benefits outweigh any potential negative impact, and its field release was proved in 1992. Expand
Successful Biological Control of Tropical Soda Apple (Solanales: Solanaceae) in Florida: A Review of Key Program Components
Host specificity tests conducted under laboratory and field conditions demonstrated that the leaf feeding beetle Gratiana boliviana Dunal was a specialist herbivore that completes development only on the target weed. Expand
Flight Phenology of Male Cactoblastis cactorum (Lepidoptera: Pyralidae) at Different Latitudes in the Southeastern United States
Initiation and timing of the 3 generational flights has importance in the current United States and Mexico monitoring program for presence and expansion of this invasive pest, development of mapping programs to identify monitoring windows and management efforts with the Sterile Insect Technique. Expand
Genetics, taxonomy, and ecology of certain species of Galerucella (Coleoptera: Chrysomelidae)
Two European chrysomelids, Galerucella calmariensis (L.) and G. pusilla (Duftschmidt), show promise as biological control agents against the weed Lythrum salicaria L.salicaria, which would increase to five the number of GalerUcella species in North America. Expand
