Abstract

Tropileloza je nametnička bolest pčelinjeg legla uzrokovana hemofagnim grinjama iz
roda Tropilaelaps. Prirodni nosioci ovih grinja su slobodno živuće divovske azijske pčele Apis
dorsata, Apis breviligula i Apis laboriosa. Tropilaelaps grinje su prešle na novog nosioca,
europsku medonosnu pčelu (Apis mellifera) nakon njezinog uvoza u Aziju. Unutar roda
Tropilaelaps se nalaze četiri vrste. Dvije vrste su sposobne parazitirati na europskoj
medonosnoj pčeli, i to: Tropilaelaps clareae i Tropilaelaps mercedesae. Za preostale dvije
vrste: Tropilaelaps koenigerum i Tropilaelaps thaii se smatra da su bezopasne za Apis mellifera.
Invazije Tropilaelaps spp. grinjama dovode do velikih šteta na pčelinjim ličinkama i
kukuljicama (malformacije legla), ugibanja mladih pčela i u konačnici do propadanja pčelinje
zajednice. Iako je tropileloza još uvijek prisutna samo u Aziji, prepoznata je kao velika prijetnja
svjetskom pčelarstvu. Stoga je uvrštena na listu opasnih zaraznih bolesti pčela Svjetske
organizacije za zdravlje životinja. U ovom radu navedene su najnovije spoznaje o biologiji
Tropilaelaps spp. grinja, štetama koje uzrokuju na pčelinjem leglu i na cijeloj pčelinjoj
zajednici, načinima dijagnosticiranja, kontroliranja i prevencije tropileloze.

Abstract (english)

Tropilaelosis is a parasitic disease of honey bee brood caused by haemophagous mites
of the genus Tropilaelaps. Non-domesticated giant Asian honey bees Apis dorsata, Apis
breviligula and Apis laboriosa are native hosts to Tropilaelaps mites. These mites spread into
the managed European honey bee (Apis mellifera) after human had introduced Apis mellifera
into Asia. There are four species in the genus Tropilaelaps. Two species: Tropilaelaps clareae
and Tropilaelaps mercedesae are damaging pests of European honey bee. The other two
species: Tropilaelaps koenigerum and Tropilaelaps thaii appear to be harmless to Apis
mellifera. Tropilaelaps mite infestation causes severe damage to honey bee larvae and pupae
(brood malformation), death of young bees and a subsequent colony decline. Although
tropilaelosis still remains confined to Asia, it is recognized as emerging threat to world
apiculture. Therefore, tropilaelosis is on the list of serious diseases which endanger the whole
world, according to the World Organisation for Animal Health. This thesis provides a current
knowledge in the main fields of Tropilaelaps spp. research, including the biology of mites,
damage on the honey bee brood and colonies, early diagnostic methods, control measures and
prevention of tropilaelosis.
