Yearlong association of insect pollinator, with flowering plants: Planted forest vs. agricultural landscape.

The yearlong association of a native bee, (Halictidae: Hymenoptera) was studied with 72 plant species in a sub-tropical planted forest and some adjacent agricultural landscapes at Multan, Pakistan. The study resulted in 66 interactions of with only 24 plant species in 15 families while other 48 plant species were not visited by this bee. The maximum abundance of (7-9 individuals) was recorded on and followed by , and (5-6 individuals). Majority (19) of plant species were visited by only 1-4 individuals. The bee activity was started in the month of March which attained its peak in May followed by a gradual decline until September. No bees were observed during the months of January and February. There was a significant positive relationship between bee abundance and number of flowering plant species. Bee abundance had a strong positive relationship with temperature while it had a strong negative relationship with relative humidity (%). Floral abundance increased with the number of flowering plant species while it was not influenced by floral span of plant species. Besides giving the floral host plants of , the current study also gives a better understanding of its seasonality along with its relationships with different biotic and abiotic factors under local conditions. These findings can help in maintaining and managing population particularly and other native bees in general at local scale.
