“…There is limited data on phylloxera response to elevated temperatures above 30°C, and these have focused only on a geographic population (Buchanan 1990), a single‐sourced genetic variant of grapevine phylloxera (Korosi et al. 2009) or under green waste composting conditions (Bishop et al. 2002, Keen et al.…”

Background and Aims: Grape phylloxera, Daktulosphaira vitifoliae (Fitch), is a significant insect pest of grapevines and can cause mild to severe economic damage to ungrafted European grapevine, Vitis vinifera L., depending on the insect clonal type. Dry heat treatment is currently recommended as a disinfestation method to restrict the spread of phylloxera to uninfested vineyards on viticultural machinery. Methods and Results: G1 and G4 first instar grape phylloxera clones were subjected to two relative humidity (30 and 100%) and four temperature (30, 35, 40 and 45°C) treatment combinations to find the optimal temperaturehumidity combination to achieve 100% phylloxera mortality over the shortest time period. Conclusions: One hundred per cent mortality of two phylloxera clonal strains was achieved at 45°C for 75 min at 30% relative humidity. Some differences in clonal susceptibility to temperature and humidity treatments were observed. Significance of the Study: A novel screening method was developed, which validated the nationally recognised dry heat disinfestation protocol for grape phylloxera. The study also highlighted that different clonal lineages of phylloxera are influenced by both temperature and humidity.

“…The monitoring and evaluation was undertaken using a randomized complete block (RCB) design consisting of two treatments (Control and Compost) × four periods of exposure (Phases) × five replicates (compost windrows‐i.e., five of the seven windrows described above). This was an adaptation of the experimental protocol developed by Bishop et al (2002) and Keen et al (2002)…”

Environmental Risk Assessment of Compost Prepared from Salvinia, Egeria densa, and Alligator Weed

et al. 2009

Approximately 70,000 m(3) of salvinia (Salvinia molesta) was removed from the Hawkesbury-Nepean River, New South Wales (NSW), Australia, during 2004. This study assessed the risks associated with applying compost prepared from aquatic weeds (AWC) to land, namely, survival and spread of aquatic and terrestrial weeds, eutrophication of waterways, accumulation of heavy metals and phytotoxicity. The results demonstrate composting is an effective method of reducing the viability of aquatic and terrestrial weeds. However, mortality of alligator weed (Alternanthera philoxeroides), which was used as an indicator plant, was significantly (P < 0.001) correlated with the temperature within the windrows and the length of time the material was subjected to composting. Conditions within the central core of the windrow were sufficient to kill the alligator weed, although not all of the aquatic weed material was exposed to the windrows' central core. This resulted in alligator weed continuing to grow at the base of the windrow. To reduce the risk of weeds surviving and spreading in aquatic and terrestrial environments it is suggested compost windrows should be located on an appropriate hard pad to enable complete mixing of the material and ensure all material is exposed to temperatures >55 degrees C for greater than three consecutive days. The likelihood of other risks associated with the AWC was low. If composting is selected as the preferred method for managing organic material harvested from waterways, then ongoing monitoring and evaluation is required to validate the composting process and ensure consumer confidence in the final product.

“…However, less well managed systems that do not efficiently turn and combine the components of the compost pile can allow insect pests to survive at the margins of the compost where temperatures do not reach lethal limits (Bishop et al 2002;Keen et al, 2002). …”

This report demonstrates a probabilistic quantitative pathway analysis model that can be used in risk assessment for plant pest introduction into EU territory on a range of edible commodities (apples, oranges, stone fruits and wheat). Two types of model were developed: a general commodity model that simulates distribution of an imported infested/infected commodity to and within the EU from source countries by month; and a consignment model that simulates the movement and distribution of individual consignments from source countries to destinations in the EU. The general pathway model has two modules. Module 1 is a trade pathway model, with a Eurostat database of five years of monthly trade volumes for each specific commodity into the EU28 from all source countries and territories. Infestation levels based on interception records, commercial quality standards or other information determine volume of infested commodity entering and transhipped within the EU. Module 2 allocates commodity volumes to processing, retail use and waste streams and overlays the distribution onto EU NUTS2 regions based on population densities and processing unit locations. Transfer potential to domestic host crops is a function of distribution of imported infested product and area of domestic production in NUTS2 regions, pest dispersal potential, and phenology of susceptibility in domestic crops. The consignment model covers the several routes on supply chains for processing and retail use. The output of the general pathway model is a distribution of estimated volumes of infested produce by NUTS2 region across the EU28, by month or annually; this is then related to the accessible susceptible domestic crop. Risk is expressed as a potential volume of infested fruit in potential contact with an area of susceptible domestic host crop. The output of the consignment model is a volume of infested produce retained at each stage along the specific consignment trade chain.
