Cold hardiness of Helicoverpa zea Lepidoptera: Paul, Minnesota, United States of America.

The presence of H. Analysis and interpretation of long term light trap data for Helicoverpa punctigera Lepidoptera: First record of Helicoverpa armigera Lepidoptera: In contrast, there was little evidence of association between heterogeneity in diapause induction and developmental variation with geographical pattern in various Moroccan populations [ 50 ]. Reduced populations of H. Areas suitable for seasonal migration-based impacts are indicated in bright green.

Populations have been high heilcoverpa, impacting significantly on key crops such as corn, soybeans, tomatoes and cotton to name a few [ 5 ].

Estimating these potential losses would be complicated by the presence of a number of pests in the USA that share a similar niche, including the closely related species H. The arrival of 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. For some crops, the sales values were available, and for others, production was gauged in weight of commodity [either pounds lbs or hundredweight cwt ].

Annals of the Entomological Society of America. The CLIMEX model has not been calibrated for insect abundance or crop losses as a function of climate suitability as was done for Thaumetopoea pityocampa [ 70 ]. Noctuidae and of its relationship to H. During the preparation of this paper, the distribution maps for H.

Right-sizing stem rust research. In the relatively short-term, the presence and continued spread of H. It may even be in the interests of the North American countries to co-invest in biological control and spread monitoring programmes in Central America and the Caribbean.

Helicoverpa armigera: current status and future perspectives in Brazil.

The various data elements used in this analysis span a range of temporal frames. Discussion Global potential distribution With its discovery in Brazil, H. 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.

The risk assessment for the USA focused mebrapa on the H. These complications suggest that there may be limited available responses such as: North American Plant Protection Organization. Changed values are indicated in bold. Investigations on Heliothis armigera Hb.

Status of American Bollworm hellicoverpa cotton at Stennar, Sudan. The diapause and irrigation scenarios were combined into a fully factorial set of scenarios. Whilst there is no direct evidence of the detection rate in this case, based on the few studies available e. Please review our privacy policy.

Damaging low temperatures can destroy tissues, and tends to have a rapid stress accumulation rate. Because CLIMEX models the weekly suitability of climate for population growth, it is possible to verify that aspect of the model as well as the geographical patterns of establishment. Noctuidae migrants as determined by Citrus pollen markers and synoptic weather systems.
