Analysis of long-term light-trap data for Helicoverpa spp. CLIMEX is a bioclimatic niche model that has been demonstrated to be well-suited to estimating the potential distribution of a wide range of taxa [ 660 ].

The geographical distribution of the Queensland fruit fly, Bactrocera Dacus tryoniin relation to climate. The level of damage caused in a crop depends in part on the abundance of adult moths, the number of eggs they lay, and the numbers of larvae surviving to the larger damaging larval instars.
For some analyses, results were set to zero where crop hosts were absent according to the MapSpaM dataset. Diapause has been studied in different parts of the species range, including: Actual losses would likely be substantially lower owing to mitigation efforts and also because it is not likely that all potentially suitable areas would have an infestation in any particular year, or that H.

The authors have declared that no competing interests exist. Helicoverpa armigera is polyphagous; females lay eggs, and the caterpillar stage can survive and feed on a very wide range of host plant species [ hhelicoverpa19 ].
