A nematode pathogen of arum lily (Zantedeschia aethiopica) revealed in the search for a potential biological control agent against this noxious weed [PDF]
, 1997 Arum or calla lily (Zantedeschia aethiopica) is an important ornamental plant throughout the world. There is a small Australian industry based in Victoria which exports rhizomes within and outside of Australia. In Western Australia Z.

Pest Management Science, EarlyView.We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.

Regional analysis of spatiotemporal trends in Colorado potato beetle abundance
Pest Management Science, EarlyView.Leveraging a large data set on Colorado potato beetles in Wisconsin, we examine spatial and temporal abundance trends. Spatiotemporal statistical models substantially improve fit and show that climate and management factors are positively associated with abundance levels.

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations [PDF]
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low.

Pest Management Science, EarlyView.The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.

Herbicidal Weed Control Methods for Pastures and Natural Areas of Hawaii [PDF]
, 2002 General methods of weed control are described. Methods of application are detailed and illustrated, including conventional foliar, low-volume (drizzle) foliar, cut-surface (notching, cut-stump, basal bark), and soil ...

Pest Management Science, EarlyView.Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Mortality in an invasive ant does not scale linearly with fipronil exposure
Pest Management Science, EarlyView.Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.

A bioeconomic model for determining the optimal response to a new weed incursion in Australian cropping systems [PDF]
Invasions by non-indigenous plant species pose serious economic threats to Australian agricultural industries. When an invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing.

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae
Pest Management Science, EarlyView.Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.
