The threshold of 10 for GI A was chosen arbitrarily as the minimum climate suitability that could produce noticeable pest impacts.
The successful establishment and spread of the species seems to have been unhindered by the presence of closely related heliothines, ostensibly in the same or similar niche. Overall, the overseas experiences suggest therefore that H. Ten specimens of H.
One, very basic issue that needs solving is the difficulty of distinguishing H. We found that the annual value of crops that would be exposed to H. Previously, the perceived threat was from goods and services being transported into North America, from various locations worldwide, including South and Central America and the Caribbean. The known global distribution of Helicoverpa armigera. Services on Demand Journal.
Discussion Global potential distribution With its discovery in Brazil, H. Dilawari, unpublished data and c Narrabri Australia where the solid thin line is for average light trap catches from [ 3546 ]and the remaining lines are for male light-trap catch dashed line and pheromone trap catch fine dashed line from [ 72 ]. The geographical distribution of the Queensland fruit fly, Bactrocera Dacus tryoniin relation to climate.
The most sensitive parameters influencing the modelled range of H. Accessed Aug Table 2 Total port interceptions for Helicoverpa species in the United States from to To facilitate this, it was also necessary to reduce the upper optimum soil moisture level SM2 and the upper soil moisture limit SM3.
Heliothine moths of Australia: In these areas it appears likely that H. In contrast, there was little evidence of association between heterogeneity in diapause induction and developmental variation with geographical pattern in various Moroccan populations [ 50 ].
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.
Accessed Apr 3. Helicpverpa uncertainties combine to helicover;a our ability to model the potential distribution of H.
Its voracity is worrisome, in its larval stage can feed on leaves, stems, shoots, inflorescences, fruits and helivoverpa Acevedo Reyes Populations have been high there, impacting significantly on key crops such as corn, soybeans, tomatoes and cotton to name a few [ 5 ]. There is presently no means of calibrating a function relating climate suitability for H.
The distribution records in Central Australia indicated in [ 12 ] and those in northern Europe include reports of transient populations. Should it spread further into these areas it is likely that H. Another potential problem lies in the close association between H.
First reported occurrence of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) in Brazil

Timing of diapause induction and overwintering success in the cotton bollworm Helicoverpa armigera Hb. Pest risk assessment of insects in sea cargo containers. Report of a pest risk analysis: Further spread westward and northwards through Peru, Ecuador, and Columbia, and northwards through Venezuela seems almost inevitable.
What is a host plant?
Insecticide resistance and mechanisms of resistance to selected strains of Helicoverpa armigera Lepidoptera: Unfortunately, the available data types from the agricultural census varied by commodity. In the relatively short-term, the presence and continued spread of H. CLIMEX is a heliclverpa niche model that has been demonstrated to be well-suited to estimating the potential distribution of a wide range of taxa [ 660 ].
Finally, the samples were analyzed in 1. Hearne Scientific Software Pty Ltd. To assess the potential impacts on cropping in the United States, data on the value of production for the year for each of the main field crop hosts of H.
It is unclear if H. Noctuidae and Coexistence with Helicoverpa zea in Southeastern Brazil. Other ten individuals were identified as H. 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.
