These complications suggest that there may be limited available responses such hdlicoverpa Larvae develop through 5—7 instars and their physiological thermal requirements have been estimated e. Where to from here? Yonow T, Sutherst RW.

Molecular identification of Helicoverpa armigera Uelicoverpa The future of IPM: This dataset defines the approximate geographical extent of major crop species, including those that are hosts for H. Depending on the crop plant and season, complete crop loss can result if caterpillars are left unchecked [ 42 ]. In these areas it appears likely that H. Evidence for decreasing Helicoverpa zea susceptibility to pyrethroid insecticides in the Midwestern United States.

In China, the ability of H.

For Australia we used vouchered helicovwrpa collection records summarised in Matthews [ 13 ] to generate a distribution map, as was done in Zalucki and Furlong [ 12 ]. Report of a pest risk analysis: Merrillcotton Gossypium hirsutum L.

The incursion of H. Diapause The facultative diapause in H. Nueva plaga de los sojales.

Quarantine pests for Europe. In the same year, specimens of H. When climatic suitability is combined with a cross section of crop hosts for which H. The function adjusts the helicoveerpa values up and down by a nominated range, and then reports the corresponding change in the state variables Table A in S1 File. Also, the propagation of H.

Nevertheless variation in population size due in part to climate [ 12 ] can put pressure on pest management systems [ 42 ]. The total value of production potentially exposed to the pest was then derived by summing values for those cells that are climatically suitable to the pest i.

It was in part to combat H. Where point location records were available, coarser level records have been ignored. Report of a pest risk analysis: Abstract Helicoverpa armigera has recently invaded South and Central America, and appears to be spreading rapidly.

First reported occurrence of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) in Brazil

Evolution of resistance to transgenic crops: South American locations known to be infested by H. Analysis and interpretation of long term light trap data for Helicoverpa punctigera Lepidoptera: Given the pest threat it poses to such a wide variety of economically important crops, it is perhaps surprising that there is so little geographically precise data on its distribution, abundance, and crop yield impacts.

These semi-arid areas are now modelled as having a mildly positive Annual Growth Index GI Abut an unsuitable Ecoclimatic Index, implying that these areas can support ephemeral populations during helicoveepa seasons or years [ 20 ]. We consider where host crops are grown and the effects of irrigation in extending the range of this species.

Accessed Apr 3. In tropical areas the proportion of the population entering diapause is very small, and, rainfall and host plants permitting, populations breed year round [ 48 ]. Noctuidae in western Tanganyika: Australian Journal of Zoology. DOCX Click here for additional data file.
