S
ince 1980’s, Japanese quince
(Chaenomeles japonica)
is cultivated as minor fruit crop in Latvia. So far, growers
have not reported any significant problems caused by invertebrate pests, however lately, total area of quince
plantations is noticeable increasing and there is possibility that some pests of rose family (Rosaceae) crop plants or
some polyphagous generalist pests may become significant pests also of Japanese quince. Therefore, objective of this
research is to study potential pests of Japanese quince in Latvia.
Research was carried out in seven biological and one integrated farmed quince plantations dispersed in whole
area of Latvia. Potential pests were studied with different methods: yellow sticky traps, pest registration on quince
plants, delta traps with sex pheromones of rose tortrix
(Archips rosana)
, large fruit-tree tortrix (Archips podana),
holly tortrix (
Rhopobota naevana)
and codling moth (
Cydia pomonella
). Also visual assessment and registration of
damaged buds, flowers, leaves and fruit was done. All studies were done during vegetation seasons of 2017 (cool and
rainy) and 2018 (hot and dry).
Pest infestation level was low in both years. Buds, flowers, leaves and fruit were almost intact. Eggs of European red
mite
(Panonychus ulmi
) were not recorded on quince twigs, however infestation of the mite was observed during
summertime in one plantation located near heavy infested orchard. Tortrix moths appeared in plantations located
near apple orchards. In all plantations, aphids (Aphididae) were caught with yellow sticky traps, but colonies of these
pests were not observed on quince plants. During 2018 when weather was particularly hot and dry, low but noticeable
infestation of garden chafer (
Phyllopertha horticola
) and black-veined white (
Aporia crataegi
) was observed.
This research was a part of ERAF project “Environment-friendly cultivation of emerging commercial fruit crop
Japanese quince – Chaenomeles japonica and waste-free methods of its processing” (No. 1.1.1.1/16/A/094).

Biography
Janis Gailis has a Master’s degree in Biology and a PhD inAgriculture. He is working in Latvia University of Life Sciences and Technologies as docent and senior
researcher since 2012. His scientific interests and activities are related with entomology (mainly Coleoptera). Main topics of Janis’ studies are diversity and
conservation of insects, integrated pest management, predatory insects as biological control agents of arthropod pests.
