Název v původním jazyce

Termination of diapause in the lime seed bug Oxycarenus lavaterae (Heteroptera: Lygaeoidea: Oxycarenidae)

Popis výsledku v původním jazyce

The true bug Oxycarenus lavaterae has spread northwards through Europe from the Mediterranean at the beginning of the 21st century. Temperature and photoperiod in particular countries are important for the prediction of further spread. The timing and conditions for the termination of winter diapause in Bulgarian and Czech populations of O. lavaterae were determined. The progress in diapause development in the Bulgarian population was monitored by changes in the duration of the pre-oviposition pe-riod under long day (18L : 6D) conditions, which decreased gradually from October to June from 98 to 10 days at 20 degrees C and 62 to 9 days at 25 degrees C. There was no change in the photoperiodic response around the winter solstice in December/January, as is recorded for many other temperate insects. Instead, most overwintering females of O. lavaterae transferred to the diapause-promoting short-day photoperiod (12L : 12D) at 25 degrees C did not start to oviposit even though they lived up to one year. The percentage of fe-males that oviposited under short day conditions gradually increased from December to May, but only reached approximately 50% at most. In the Czech Republic, the number of individuals observed resting in overwintering aggregations on tree trunks gradually decreased up to early June. This bug seems remain in diapause until lime trees fl ower and their seeds become available.
