Abstract:
... The fruit fly, Bactrocera invadens is an alien invasive pest of mango in Africa. The predatory African weaver ant, Oecophylla longinoda is being promoted for managing B. invadens and classical biological control with the Opiine parasitoid, Fopius arisanus is also underway. The current study investigated interactions between these two natural enemies. Specifically we assessed whether semiochemicals ...

Abstract:
... All entomopathogenic fungi infect insects by direct penetration through the cuticle rather than per os through the gut. Genetic transformation can confer fungi with per os virulence. However, unless the recipient isolate is nonpathogenic to the target insect, mortality caused by a transgenic isolate cannot be attributed solely to oral virulence due to the potential for some simultaneous cuticular ...

Castanea; Cryphonectria parasitica; Hypovirus; biological control; field experimentation; fungi; orchards; stems; trees; virulence; viruses; Spain
Abstract:
... Chestnut blight is controlled in Europe by using Cryphonectria hypovirus CHV1, a non-encapsulated RNA virus. The chestnut blight fungus, Cryphonectria parasitica, is weakened by the virus, and healing tissue growth occurs in the host tree. Transmission of this cytoplasmic hypovirus is restricted by the incompatibility system of the fungus, so that the hypovirus can be transmitted only between isol ...

Abstract:
... Soil habitat conditions that promote abundance and persistence of entomopathogenic nematodes (EPNs) might be encouraged by reduced tillage and compost amendments. We hypothesized that altered soil management with reduced tillage, cover crops (clover and barley), and compost (100kg of N/ha), would increase survival and biocontrol services of EPNs, compared with conventional management. Field trials ...

Abstract:
... The combined release of species of generalist predators can enhance multiple pest control when the predators feed on different prey, but, in theory, predators may be excluded through predation on each other. This study evaluated the co-occurrence of the generalist predators Macrolophus pygmaeus Rambur and Orius laevigatus (Fieber) and their control of two pests in a sweet pepper crop. Both predato ...

Abstract:
... Miconia calvescens is a small tree from the Neotropics that has become an aggressive invader of forest ecosystems in the Pacific. Classical biological control is the sole sustainable method for controlling such invasions. Among the numerous pathogens that have been found on miconia, the fungus Coccodiela miconiae stands out as a very promising biocontrol agent. It is often found in native situatio ...

Abstract:
... Despite efforts of eradication and sanitation, Phytophthora ramorum persists in the United States and abroad. Fungicides have limited effectiveness, but there are concerns that they may only inhibit pathogen growth and hasten resistance development after repeated fungicide applications. Biological control is an active control measure that can work continuously as long as the agent is alive and act ...

Abstract:
... Plant-provided food may enhance survival and establishment of omnivorous predators on target crops but on the other hand they may adversely affect predation rates and thus their potential for biological control of target pests. However, it is not known how predation is affected by plant food quality and prey density. The omnivorous predator Macrolophus pygmaeus is commonly used in augmentative rel ...

Abstract:
... Candida sake CPA-1 is an antagonistic yeast that has previously been shown to effectively control Botrytis bunch rot in grapes. The efficacy of biological control agents is dependent on their survival, which may also depend on climatic conditions. However, few studies have evaluated the effect of abiotic factors affecting the survival of biological control agents, such as temperature (T) or relati ...

Abstract:
... The woodwasp, Sirex noctilio, is a significant global pest of exotic pine plantations in the Southern Hemisphere and now threatens native pine forests in North America. Management in Australia relies on biocontrol using the nematode, Deladenus (=Beddingia) siricidicola (Bedding), which infects and sterilises females who then further disperse the nematode. This pest is spreading into warmer regions ...

Abstract:
... South Africa has one of the world’s biggest gold mining regions with an associated problem of acid mine drainage (AMD), which increases the bioavailability of heavy metal contaminants in water. The prevalence of water hyacinth (Eichhornia crassipes) in South African water systems, despite the release of seven biocontrol agents since 1974, is often attributed to high levels of eutrophication. Metal ...
