Abstract (croatian)

Žuta kukuruzna sovica (Helicoverpa armigera Hübner) značajan je polifagni štetnik kukuruza, duhana, pamuka, slanutka i rajčice. Štete čine gusjenice ishranom na vegetativnim i generativnim dijelovima biljaka domaćina. Štete u svijetu procjenjuju se na dvije milijarde dolara godišnje. Rasprostranjena je na području Azije, Afrike, Južne Amerike, Europe i Australije. Migratorna je vrsta i može se kretati na veće udaljenosti. Godišnje ima 2 do 3 generacije na našim prostorima, a u tropskim uvjetima može razviti do 11 generacija. Pojavi žute kukuruzne sovice pogoduju visoke temperature tijekom proljetnog i ljetnog razdoblja te veće količine oborina tijekom proljeća. Porastom temperatura skraćuje se vrijeme potrebno za čitav životni ciklus. S obzirom na to da se do kraja sljedećeg stoljeća predviđa povećanje srednje dnevne temperature za 3°C, može se očekivati povećanje broja generacija i štetnosti H. armigera. Zbog nedostatka raspoloživih mjera suzbijanja, praćenje biologije i migracijskog kretanja H. armigera važno je za procjenu rizika od prodora na neko novo područje ili usjev.

Abstract (english)

The cotton bollworm (Helicoverpa armigera Hübner) is a major polyphagous pest of corn, tobacco, cotton, chickpeas, and tomatoes. Damage is caused by caterpillars that feed on the vegetative and generative parts of host plants. The damage in the world is estimated at two billion dollars per year. It is widespread in Asia, Africa, South America, Europe and Australia. It is a migratory species and can travel greater distances. In our area it has 2-3 generations per year, in tropical conditions it can develop up to 11 generations per year. The occurrence of the cotton bollworm is favored by high temperatures during the spring and summer and higher rainfall in spring. As temperatures increase, the time required for the entire life cycle decreases. Considering that the average daily temperature is expected to increase by 3°C by the end of the next century, an increase in the number of generations and the harmfulness of H. armigera can be expected. In the absence of control measures, monitoring the biology and migratory movements of H. armigera is important to assess the risk of invasion into a new area or crop.
