Fly traps are being used to monitor populations of Old World screwworm (OWS) flies in Iraq. We evaluated trapping systems for seasonality and trap type and compared the results with monitoring of OWS flies using myiases on animals. Fly catches increased during spring and autumn with low catches during the hot, dry summer and the cold winter. The effectiveness of the sticky trap/Swormlure and LuciTrap/Bezzilure for OWS flies could not be determined because no OWS were caught during the comparison period in 2009. The LuciTrap caught more flies of all other species than the sticky trap during this comparison. The numbers of myiases detected on animals in Iraqi provinces from 1996 to 2013 are provided. The high numbers of myiases in most provinces in the late 1990s were followed by lower numbers and subsequent apparent elimination in about half of the provinces. Myiases were detected mainly in sheep (77.0%) and goats (16.7%). A temporal comparison of OWS fly detection with traps and animal myiases in Babil province demonstrated a similar sensitivity and a weak correlation between the two methods. We recommend that both fly trapping and inspection of animals for myiases are used for the detection or monitoring OWS fly populations and that Iraq and the international organisations initiate an area-wide integrated OWS fly program, including the sterile insect technique, with the aim of eradicating the OWS fly from Iraq.

Environmental and phylogeographical determinants of the distribution of the Old World screwworm fly in Indonesia.

The Old World screwworm (OWS) fly, Chrysomya bezziana, is an obligate parasite of livestock, and the myiasis caused by its larval infestations is economically important in Indonesia. The current spatial distribution of such a pest depends on two main factors: the current environmental conditions in which it can survive; and, its ability to occupy those environments by dispersal, which can be inferred from phylogeography and population genetics. These indicate that all OWS flies in Indonesia have mitochondrial cytochrome b (cyt b) haplotypes of the Asian lineage, and the regional separation of its four sub-lineages is the result of infrequent long-distance dispersal.

The Old World screwworm (OWS) fly, Chrysomya bezziana (Diptera: Calliphoridae), is a major economic and welfare problem for humans and animals in the Old World tropics. Using a bootstrapped log likelihood ratio test of the output of Procrustes principal components and canonical variates analyses for a small sample of museum specimens from which 19 2D wing landmarks had been collected: (1) a consistent and statistically significant difference exists between landmark configurations derived from wings of pinned specimens and those removed from the body and mounted on slides; (2) a highly statistically significant sexual dimorphism in wing morphometry was identified; and (3) a highly statistically significant difference in wing morphometry between populations of the OWS fly from Africa (Tanzania, South Africa Sudan, Zaire, Zimbabwe,) and Asia (Sumba, Indonesia) exists. These results show that wing orientation and gender must be considered when conducting morphometric investigations of OWS fly wings.

Agent-based modelling has proven to be a promising approach for developing rich simulations for complex phenomena that provide decision support functions across a broad range of areas including biological, social and agricultural sciences. This paper demonstrates how high performance computing technologies, namely General-Purpose Computing on Graphics Processing Units (GPGPU), and commercial Geographic Information Systems (GIS) can be applied to develop a national scale, agent-based simulation of an incursion of Old World Screwworm fly (OWS fly) into the Australian mainland. The development of this simulation model leverages the combination of massively data-parallel processing capabilities supported by NVidia's Compute Unified Device Architecture (CUDA) and the advanced spatial visualisation capabilities of GIS.

The Old World screwworm (OWS) fly, Chrysomya bezziana, is a serious pest of livestock, wildlife and humans in tropical Africa, parts of the Middle East, the Indian subcontinent, south-east Asia and Papua New Guinea. Although to date Australia remains free of OWS flies, an incursion would have serious economic and animal welfare implications. For these reasons Australia has an OWS fly preparedness plan including OWS fly surveillance with fly traps.
