Hymenopteran Parasitoids Of Fall Armyworm (Spodoptera Frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)) In Australia, With The Description Of Five New Species In The Families Braconidae And Eulophidae, Erinn P. Fagan-Jeffries, Melina M. Miles, Tareva-Chine C.

Biosecurity Research Articles

Fall armyworm, Spodoptera frugiperda (J.E. Smith) is an invasive pest of agricultural crops including sweet corn and maize. The moth was first recorded in Australia in January 2020 and is now considered established in most states and territories, and research is underway to develop management strategies. Extensive rearing of S. frugiperda larvae and eggs occurred from March 2020 to April 2023 to understand the parasitoid complex present in Australia and identify potential biological control agents. We report here on the hymenopteran parasitoids reared during this period, which were identified using a combination of morphology and COI DNA barcoding, and provide …

A Spatio-Temporal Modelling Approach To Understand The Effect Of Urban Fruit Fly Outbreaks On Peri-Urban Orchards, Andrew Broadley, Rieks Van Klinken, Dean R. Paini, Matthew Hill, Elliot T. Howse

Horticulture Research Articles

Urban areas are well-known sources of fruit fly introduction and unmanaged populations pose a high risk of dispersal to surrounding agricultural areas. Although management of urban fruit fly populations is recognised as being important for area-wide control programmes, its relative importance is rarely quantified. Identifying possible sources of fruit fly populations is important to the success of area-wide programs, as well as to on-farm management. We developed a modelling approach to analyse the spatio-temporal connectivity of fruit fly across urban-agriculture boundaries. For a case study, we examine Mediterranean fruit fly, Ceratitis capitata, outbreaks in two fruit growing …

Pest Slugs And Snails And Their Management In Broadacre Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Slugs and snails cause damage to all broadacre crops. Numbers of slugs and snails have increased in broadacre cropping in Western Australia (WA) with the use of minimum tillage and stubble-retention practices. These systems increase the organic content of paddocks and soil moisture content, leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly in the Mediterranean region. They have similar lifecycles, which means similar management techniques can be employed to control them in broadacre crops.

Effective management requires application of controls that coincide with different phases of the …

The Golden Native Drone Fly (Eristalinus Punctulatus) Is An Effective Hybrid Carrot Pollinator That Lives Within Australian Crop Agroecosystems, Abby E. Davis, Lena A. Schmidt, Karen C B S Santos, Lucie Martin, Samantha Harrington, Marizio Rocchetti, Brad Hocking, Derek Wright, Cameron J. Spurr, David F. Cook, Romina C. Rader

Horticulture Research Articles

1. Native insect flower visitors can be important contributors to crop pollination, yet little is known of their pollination abilities and the resources (habitat) they need to be supported within crop agroecosystems.
2. Here, we compared the abundance and pollination abilities of the golden drone fly (Eristalinus punctulatus) to the European honey bee (Apis mellifera) in hybrid carrot crop fields known to produce variable seed yields in regional New South Wales, Australia. We further observed the egg-laying behaviours of female golden drone flies at a commercial berry orchard to provide insight into the habitat needs of this species. …
