Helicoverpa armigera jest szeroko rozpowszechniona w Azji, Afryce, Australii i śródziemnomorskiej Europie. H. armigera jest glównym szkodnikiem bawelny, ciecierzycy, slonecznika, pomidora, kukurydzy, sorgo, bajry, lucerny, warzyw i tytoniu. Tabela żywotności plodności (dla samic) jest przydatna w określaniu przydatności żywicieli i etapu cyklu życiowego szkodnika, co przyczynia się do trendu populacji. Ta statystyka jest wrodzoną zdolnością wzrostu, która jest również nazywana prawdziwym wewnętrznym wskaźnikiem przyrostu naturalnego (rm). W badaniu określono również skończone tempo wzrostu, które oznacza liczbę osobników dodanych do populacji na glowę w jednostce czasu. Średnia dlugośc pokolenia wynosila 42,25, 44,81 i 45,26 dni odpowiednio na lucernie, sorgo i ciecierzycy. Byla ona najniższa na lucernie (42,25), natomiast najwyższa na ciecierzycy (45,26 dni). Wewnętrzne tempo naturalnego wzrostu liczebności (rm) wynosilo 0,1185, 0,1195 i 0,1302 samicy na samicę dziennie odpowiednio na sorgo, lucernie i ciecierzycy. Biorąc pod uwagę wartości "rm", żywiciel może byc ulożony jako ciecierzyca>lucerna>sorgo.
