In Australia the model sensitivity was perfect 1 in relation to the location records for persistent populations. The pest status of H. The northern limit for records of permanently established populations in Europe is in southern France, Bulgaria and northern Greece [ 11 ].

The likely natural dispersal routes preclude aggressive incursion responses, emphasizing the value of preparatory communication with agricultural producers in areas suitable for invasion by H. Helicoverpa armigera is a polyphagous pest of agricultural helioverpa. Sutherst RW, Maywald G. Author information Article notes Copyright and License information Disclaimer.

These data were mapped by number of independent interceptions at each port, and analysed for trends through time. Forecasting Helicoverpa populations in Australia: The emergence and control of overwintering Helicoverpa armigera pupae in southern New South Wales.

Insecticide resistance and mechanisms of resistance to selected strains of Helicoverpa armigera Lepidoptera: Using the MapSpam data, H. The mtDNA marker method of species differentiation of Behere et al.

Population changes and forecasting pest pressure. Helicoverpa armigera is climatically well suited to the agricultural regions of South America, and unsurprisingly, it is spreading rapidly throughout Argentina, Bolivia, Brazil, Paraguay and Uruguay, and most recently into Cost Rica and Puerto Rico Fig.

Australian Journal of Zoology. Noctuidae and other moths in early summer observed with radar in northern Heliclverpa.

To characterise the threat posed by H. Improving this method to include other Helicoverpa species e. There are no apparent barriers to its spread through Central America to the point where it could migrate into the agricultural regions of North America.

Erjun Ling, Academic Editor. The known helicoferpa distribution of Helicoverpa armigera.

Irrigation Helicoverpa armigera is found in areas that under natural rainfall conditions extended periods with soil moisture below permanent wilting point, and which appear too arid to support sufficient crop growth and hence population growth for H. Its rapid spread into the Caribbean also reflects its strong migratory abilities. Further spread westward and northwards through Peru, Ecuador, and Columbia, and northwards through Venezuela seems almost inevitable.

When climatic suitability is combined with a cross section of crop hosts for which H. The origins of infestations of diamondback moth, Plutella xylostella L. Molecular markers to discriminate among four pest species of Helicoverpa Lepidoptera: Globally, over four hundred million hectares of Bt crops have been planted, and resistance in a number of species has been on the increase [ 87 ].

For all crops the area harvested acres was available. This article has been corrected. Compared with the model of Zalucki and Furlong [ 12 ], these modifications resulted in a significant reduction in the area in central Australia that was apparently suitable for supporting persistent populations. During the preparation of this paper, the distribution maps for H.
