Combinations of Microbial and Insect Biocontrol Agents for Management of Weed Seeds
Important roles for biotic agents in integrated weed management include preventing seed production and weed emergence from the seed bank. Seed-attacking microorganisms have been described for a limited number of economically important weeds and serve as examples illustrating the potential for reducing weed seed production. Innundative releases of seed-feeding insects have also successfully redu...
متن کاملComplex interactions among biocontrol agents, pollinators, and an invasive weed: a structural equation modeling approach.
Herbivores, seed predators, and pollinators can exert strong impacts on their host plants. They can also affect the strength of each other's impact by modifying traits in their shared host, producing super- or sub-additive outcomes. This phenomenon is especially relevant to biological control of invasive plants because most invaders are attacked by multiple agents. Unfortunately, complex intera...
متن کاملMaximising the contribution of native-range studies towards the identification and prioritisation of weed biocontrol agents
Effective study in the native range to identify potential agents underpins all efforts in classical biological control of weeds. Good agents that demonstrate both a high degree of host specificity and the potential to be damaging are a very limited resource and must therefore be carefully studied and considered. The overseas component is often operationally difficult and expensive but can contr...
متن کاملExploratory survey in China for potential insect biocontrol agents of mile-a-minute weed, Polygonum perfoliatum L., in Eastern USA
A survey was undertaken in China between 1996 and 2001 for phytophagous insect fauna associated with mile-a-minute weed, Polygonum perfoliatum L. (Polygonaceae). The purpose was to identify potential biological control agents for this invasive plant in the eastern USA. The survey covered 23 provinces including northeastern China, where the climate is similar to that of the eastern USA, and sout...
متن کاملWhat Magnitude Are Observed Non-Target Impacts from Weed Biocontrol?
A systematic review focused by plant on non-target impacts from agents deliberately introduced for the biological control of weeds found significant non-target impacts to be rare. The magnitude of direct impact of 43 biocontrol agents on 140 non-target plants was retrospectively categorized using a risk management framework for ecological impacts of invasive species (minimal, minor, moderate, m...
