Impact of insect pollinators on yield and fruit quality of strawberry

Abstract EN

Investigations were conducted to determine the insect pollinators visiting strawberry blossoms and their impact on fruit production.

Various pollinators observed during the blooming period of strawberry were viz.

Apis mellifera, Apis cerana, Apis florea.

Apis dorsata, soil nesting solitary bees such as Andrena leana and A.

ilerda, butterflies, houseflies, syrphid flies and some beetles.

The percentage of fruit set was much higher in open pollinated plants than control.

There was 11.20 per cent malformed fruit in open pollinated plots as compared to 17.44 per cent in controlled one.

Further the fruits obtained from the open pollinated plants were of good quality and large as compared to the controlled plants.

Growers are recommended to take advantage of the several pollinators, either the honey bee or the native pollinators (Syrphidae and native bees).

The importance of diversifying pollination sources, avoiding the dependence on a single specific group is stressed.

This study also suggests measures which envisage the conservation, establishment and increase of native pollinators’ populations in the typical agro-ecosystem of region.
