Diel and seasonal patterns and changes in activity patterns of several aquatic beetle and bug species were revealed. The effects of environmental (mainly meteorological) factors on dispersal activity were determined. Changing of solar elevation angle (together with detectability of water surfaces) stated as the main influential factor on number of individuals and species richness of flying insects. Possible connections between breeding period and dispersal activity were investigated in detail, as like the effects of changes in lunar phases
A Sigara lateralis vĂĄndorlĂĄsi sajĂĄtossĂĄgai (2000, 2005)
2000 és 2005 években végzett monitorozó jellegƱ
vizsgĂĄlataink sorĂĄn a vĂzibogarak Ă©s a vĂzipoloskĂĄk vĂĄndorlĂĄsi szokĂĄsait, vĂĄndorlĂĄsuk napszakos Ă©s Ă©vszakos ritmusĂĄt tanulmĂĄnyoztuk. Heti gyakorisĂĄgĂș, 24 Ăłra idĆtartamĂș, ĂłrĂĄnkĂ©nti bontĂĄsban vĂ©gzett mintavĂ©teleink sorĂĄn 9x3 mĂ©teres fekete fĂłliĂĄkon csapdĂĄztuk a rovarokat a HortobĂĄgyi Nemzeti Park terĂŒletĂ©n lĂ©vĆ HagymĂĄs-lapos mocsĂĄr mellett. A mintavĂ©teleket 2000-ben mĂĄrcius elejĂ©tĆl jĂșlius elejĂ©ig, a vĂztĂ©r kiszĂĄradĂĄsĂĄig vĂ©geztĂŒk, mĂg 2005-ben

idĆszakban szinte kizĂĄrĂłlag az esti/alkonyati periĂłdusban (20-23 Ăłra között) kel szĂĄrnyra nagy egyedszĂĄmban. 2000-ben a korĂĄbban Ă©rkezĆ felmelegedĂ©s miatt mintegy 3 hĂ©ttel korĂĄbban indult a vĂĄndorlĂĄs (mĂĄjus vĂ©gĂ©n) mint a 2005 Ă©vi mintavĂ©telek sorĂĄn (jĂșnius közepĂ©n). A 2005 Ă©vi adatok alapjĂĄn szignifikĂĄnsan magasabb a migrĂĄlĂł egyedek között a

In 2000 and 2005 we studied the daily and seasonal
dynamics of the dispersal of aquatic insects by monitoring the insects attracted to highly polarizing horizontal shiny black plastic sheets with 9Ă3 meters area. In our paper the seasonal and daily dynamics of the migration of the Sigara lateralis are compared based on the changing of mean numbers of individuals in the two studied year. In 2005 the
seasonal migration began latter than in 2000. We discovered that water bugs migrate dominantly in the morning and/or at early evening. The daily migrations were not different in the two studied years. The abundance of the male and female bugs was significant in point of the hourly partition
Effect of the wind speed on the migration activity of aquatic insects (Coleoptera, Heteroptera) | A szĂ©lsebessĂ©g vĂĄltozĂĄsĂĄnak hatĂĄsa a vĂzirovarok aktivitĂĄsĂĄra (Coleoptera, Heteroptera)
A vĂzirovarok Ă©vszakos Ă©s napszakos migrĂĄciĂłja Ă©s az ezt
befolyĂĄsolĂł környezeti tĂ©nyezĆk hatĂĄsa csak kevĂ©ssĂ© ismert. KutatĂĄsunk sorĂĄn 9Ă3 mĂ©teres fekete fĂłliĂĄk alkalmazĂĄsĂĄval, 2000. mĂĄrcius Ă©s jĂșlius között heti gyakorisĂĄggal, 24 ĂłrĂĄs mintavĂ©teli idĆszakokban vizsgĂĄltuk a vĂzibogarak Ă©s

The seasonal and diel flight periodicity of aquatic insects and the environmental factors governing it are poorly understood. The daily and seasonal migration of the aquatic beetles and aquatic bugs were studied. The samplings were made for 24 hours weekly between March and July 2000 by
9Ă3 m black foils, samples were separated by hours. In every sampling hour the wind speed was measured by a pocket anemometer. We observed that over 12 km/h wind speed intensity the migration of aquatic Coleoptera and
Heteroptera was totally blocked. Between 6 and 12 km/h wind speed intensity there are significant negative correlation between the number of migrating individuals and wind speed, but below 6 km/h wind speed intensity the migration controlling effects of the wind speed was not certifiable
