  • Spatial ecology of Dermolepida albohirtum, a major pest of sugarcane in Queensland: importance of a landscape approach
    2011
    Co-Authors: François-régis Goebel, Nader Sallam
    Abstract:

    Ecology has become increasingly permeated by the notion that everything takes place within a spatial context and that the distribution of habitat may strongly impact on distribution, dynamics and evolution of natural populations. In the agricultural context, understanding the influence of landscape structure (i.e. arrangement, connectivity and quality of habitat patches) on the movements of insect pests and pest outbreaks has become essential for implementing good pest management strategies. The subterranean habitat of white grubs ("larvae") and ability of beetles ("adult") to fly through the landscape once emerged make these insects difficult to manage. Adult dispersal depends on spatial and environmental factors that are generally poorly understood in agricultural systems. Beetles spend much of each year as larvae, feeding actively on many roots of food crops (sugarcane, rice, sorghum, vegetables, grain legumes, pastures, etc.) as well as garden Lawns and Turf of golf courses. In Australia, 19 species of scarab beetles ('canegrubs') attack sugarcane and the greyback canegrub Dermolepida albohirtum Waterhouse (Coleoptera: Scarabaeidae) is the most devastating pest, with estimated annual losses of AU$10 million. Information on the population dynamics is available at the field scale but studies have mainly focused on grubs and chemical management strategies for many years. However, information is scattered in many sources, particularly information on the adult behaviour at both the field and landscape scale. Major factors such as flight behaviour, feeding, resting, mating and oviposition sites in sugarcane, other crops and trees are little documented and mainly rely on old field observations. The lack of information on beetle behaviour impedes understanding of the distribution of this pest and hence application of efficient control methods. This paper provides an overview of the information already available on the ecology of this pest and present new tools that are currently used to investigate adult movement and damage distribution and the influence of the vegetation surrounding the sugarcane areas.

  • pest categorisation of popillia japonica
    EFSA Journal, 2018
    Co-Authors: Claude Bragard, Annemarie Fejer Justesen, Christer Sven Magnusson, Panagiotis Milonas, Katharina Dehnenschmutz, Josep Anton Jaques Miret, Paolo Gonthier, Marieagnes Jacques, Juan A Navascortes
    Abstract:

    The Panel on Plant Health performed a pest categorisation of Popillia japonica (Coleoptera: Scarabaeidae) for the EU. P. japonica is a distinguishable species listed in Annex IAII of Council Directive 2000/29/EC. It is native to Japan but established in the USA in the early 20th century. It spreads from New Jersey to most US states east of the Mississippi, some to the west and north into Canada. P. japonica feeds on over 700 plant species. Adults attack foliage and fruit surfaces. They can cause serious injury to tree fruits and soft fruit, vegetable crops, ornamental herbaceous plants, shrubs, vines and trees. Larvae are root feeders regarded as serious pests of Lawns and Turf, vegetables and nursery stock. Adults emerge during the summer and can fly short distances on warm sunny days. The life cycle is usually completed in one year. In cooler regions, development takes two years. P. japonica occurs in the EU in the Azores (Portugal), Lombardy and Piedmont (Italy) where it is under official control. Adults are suspected of being able to spread on aircraft as hitchhikers, i.e. without host plants. Soil accompanying plants for planting provides a pathway for further introductions. Hosts are widely available within the EU. Climatic conditions across central and parts of southern EU are suitable for development in one year. Across parts of northern Europe development over two years is likely. Without control, impacts could be expected on a range of plants. Phytosanitary measures are available to reduce the likelihood of introduction of P. japonica. All criteria assessed by EFSA for consideration as a potential Union quarantine pest are met. Plants for planting are not necessarily the main means of spread so P. japonica does not satisfy all criteria necessary for it to be regarded as a Union regulated non-quarantine pest (RNQP).

  • entomopathogenic nematodes for control of insect pests above and below ground with comments on commercial production
    Journal of Nematology, 2012
    Co-Authors: Lawrence A Lacey, Ramon Georgis
    Abstract:

    Entomopathogenic nematodes (EPNs) have been utilized in classical, conservation, and augmentative biological control programs. The vast majority of applied research has focused on their potential as inundatively applied augmentative biological control agents. Extensive research over the past three decades has demonstrated both their successes and failures for control of insect pests of crops, ornamental plants, trees and lawn and Turf. In this paper we present highlights of their development for control of insect pests above and below ground. The target insects include those from foliar, soil surface, cryptic and subterranean habitats. Advances in mass-production and formulation technology of EPNs, the discovery of numerous efficacious isolates/strains, and the desirability of reducing pesticide usage have resulted in a surge of commercial use and development of EPNs. Commercially produced EPNs are currently in use for control of scarab larvae in Lawns and Turf, fungus gnats in mushroom production, invasive mole crickets in lawn and Turf, black vine weevil in nursery plants, and Diaprepes root weevil in citrus in addition to other pest insects. However, demonstrated successful control of several other insects, often has not lead to capture of a significant share of the pesticide market for these pests.
