A tale of two trapping methods: Our objective is to detail areas at risk in North and South America at a fine spatial scale, discuss the risk of spread and impacts, and suggest interim mitigation strategies to delay the apparently inevitable invasion of North America.

Tracking Resources through Space and Time; The pest status of H. The failure so far of H.

Potential cropping impacts in the United States 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. For some crops, the sales values were available, and for others, production was gauged in weight of commodity [either pounds lbs or hundredweight cwt ]. The spread of H. How to cite soia article. This dataset consists of long-term monthly average values for minimum temperature, maximum temperature, precipitation, and relative humidity at and hr.

Quarantine pests for Europe. In this model we noted that the cold limits were most important for helidoverpa the potential range of H.


To facilitate this, it was also necessary to reduce the upper optimum soil moisture level SM2 and the upper soil moisture limit SM3. Helicoverpa armigera is a polyphagous pest of agricultural crops. Noctuidae from Paraguay and Uruguay. Linking climate helicovverpa, spread rates and host-impact when estimating the potential costs of invasive pests.

Open in a separate window. The results of this process for each of the irrigation scenarios were combined, drawing on the helicovera for the irrigated scenario where the GMIA5 dataset indicated that irrigation was practiced, and the natural rainfall scenarios elsewhere. Report of a pest risk analysis: The ecology of Heliothis species in relation to agroecosystems.

Noctuidae in northern New South Wales, Australia: For Australia we used vouchered specimen collection records summarised in Matthews [ 13 ] to generate a distribution map, as was done in Zalucki and Furlong [ 12 ]. Realised fecundity is a function of adult longevity generally 7—20 days in the laboratory e. The Memoirs of the Entomological Society of Canada 40 1: Estimating the spatio-temporal risk of disease epidemics using a bioclimatic niche model.

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

Investigations into the development and survival of Heliothis spp in south-east Queensland: Computers and Electronics in Agriculture. For all crops the area harvested acres was available. The facultative diapause in H. Data Availability All relevant data are within the paper and its Supporting Information files.

Africa [ 4950 ], Australia [ 515253 ], Greece [ 54 ], Israel [ 41 ], India [ 55 ], China [ 56 ] and Japan [ 57 ]. Furthemore, the extensive production of host crops, facilitates their abundance and propensity to disperse in wind systems, thus, they will continue to spread beyond South and Central America Kriticos et al.


Heliothinae en el departamento de Amambay, Paraguay. Annual Review of EntomologyPalo Alto, v. Western Australian Department of Agriculture; Composite risk mapping The diapause and irrigation scenarios were combined into a fully factorial set of scenarios. However, DNA analysis to confirm the species has not been performed and its distribution in the country is unknown.

Changed values are indicated in bold. The various data elements used in this analysis span a range of temporal frames. In Brazil, the species shows a high adaptation capability, strong population growth, widespread distribution within different regions, and the ability to feed and develop on different host species.


Diapause has been studied yelicoverpa different parts of the species range, including: Results Potential distribution The potential distribution, ignoring the distribution of specific crop hosts, based on EI suitable for persistent populations and GI A temporary seasonal range expansion agrees well with the known distribution of this species Fig. Noctuidae within the Sudan Gezira in realtion to cropping pattern and pest control on cotton.

Unfortunately, the available data types from the agricultural census varied by commodity. Molecular identification of Helicoverpa armigera Noctuidae: Table 2 Total port interceptions for Helicoverpa species in the United States from to
