Abstract
Skakavci selci jedni su od najvećih svjetskih gospodarskih štetnika. Gotovo svi aspekti njihova života ovisni su o temperaturi, uključujući i prijelaz iz solitarne u gregarigenu životnu fazu. Međutim, dostupna istraživanja o utjecaju temperature na njihov životni ciklus su oskudna i nepotpuna. U Ustanovi Zoološki vrt grada Zagreba provedeno je istraživanje o utjecaju različitih temperatura na trajanje inkubacije jaja, trajanje stadija između presvlačenja i mortalitet jedinki. Skakavci su uzgajani unutar ustanove, u četiri terarija s različitim temperaturnim uvjetima – maksimalna temperatura 20 ± 2°C, 25 ± 2°C, 30 ± 2°C i 35 ± 2°C. Uzgoj je djelomično omela velika smrtnost nepoznatog uzroka, a stadij imaga jedinke su dostigle u dva od četiri terarija. Očekivano, pri višim temperaturnim uvjetima trajanje pojedinih razvojnih stadija je u pravilu kraće, no razlike nisu znatne osim u usporedbi s uzgojnim uvjetima najniže temperature. Mortalitet jedinki je, s druge strane, bio značajno manji pri nižim temperaturama. Temperatura naravno nije jedini čimbenik koji utječe na njihov životni ciklus, no svakako je jedan od temeljnih. Klimatske promjene i globalno zatopljenje imati će veliki utjecaj na njihov životni ciklus, a time i najezde, stoga su potrebna dodatna istraživanja.
Abstract (english)
The migratory locust is one of the world's biggest economic pests. Most aspects of its life are temperature dependent, including transition to gregarious phase. However, the available data on the impact of temperature on their life cycle are scarce and incomplete. This research was conducted in Zagreb Zoo on the effect of temperature on the egg incubation period, duration of periods between moulting, and mortality. Locusts were bred and kept in four terrariums under different temperatures - maximum temperature 20 ± 2 °C, 25 ± 2 °C, 30 ± 2 °C, and 35 ± 2 °C. Breeding was partially interrupted by high mortality of an unknown cause, and adult phase was reached in two of four terrariums. As expected, at higher temperatures the duration of individual development stages was shorter, but differences were not significant except in comparison to the lowest temperature. However, the mortality rate was significantly lower at lower temperatures. While temperature is not the only factor influencing their life cycle, it is certainly one of the fundamental ones. Global climate changes will likely have a major impact on this species, including their gregarious phase, so further research is needed.
