...recorded as 4.34 to 5.56 honey bees per 250 flowers. Apple fruits yield per tree ranged between 214.56 to 218.64 in 2013 and 2014 respectively. Average fruit weight varied between 124.84 to 127.34 g, average number of seeds varied between 7.95 to 7.73 seeds per fruit and yield per tree was recorded between 28.92 to 31.65 kg per tree. Number of Apple fruits per tree ranged between 145.72 to 164.58 in 2013 and 2014, respectively. Average fruit weight varied betw...

... is a serious disease of honey bees worldwide that inflicts considerable economic losses to beekeepers. All work was undertaken in a commercial apiary that showed visual signs of AFB infection. Twenty four hives positive for AFB were identified from the apiary (4 colonies in each replicate). Half of the colonies were treated with shook swarm method while other half were left without any treatment. The treated colonies showed significant difference from untreat...

ROLE OF HONEY BEES FORAGING ACTIVITIES IN INCREASED FRUIT SETTING AND PRODUCTION OF APPLES APIS MELLIFERA MALUS DOMESTICA

...on (T ) , pollination by honey bees only (T ), natural pollination augmented with honey bees (T ) and no pollination (T ,control). There was a significant increase in the apple fruit setting and weight gain in pollinated plants compared to non-pollinated plants. Maximum number of fruits per panicle were 5.33±0.51(Mean±SE) whereas the highest fruit weight 170±2.65g (Mean±SE) was recorded in plants ...

Residual effect of lambda-cyhalothrin on abundance of insect pollinators in marigold field patch

...n semi-field experiment, honey bees were exposed to insecticide treated
plants for one hour. The mortality rate of honey bees in the control and insecticide
exposed group was compared. Overall, a significant decline in plant pollinators was
observed after application of lambda-cyhalothrin on the patch of marigold plants.
Lambda-cyhalothrin caused significant mortality (15/20=75%) in

Effect of Insecticides on the Longevity of Apis mellifera L. (Hymenoptera: Apidae)

...pal duration starts. The honey bees were caged after pupal duration starts and marked with permanent marker for adult data recording. The data was recorded daily for 30 days. The effects of different chemical insecticides (nitenpyram @75ml/acre- new chemistry, cyhalothrin; nok-out @200ml/ acre, tycon; emamectin benzoate @ 200ml/acre) on egg presence, egg hatching, larval duration, pupal period and adult longevity were examined. Results revealed that the nitenp...

Foraging Behavior and Pollination Ecology of Bumble Bee and Honey Bee in Pakistan; A Review

... justify;">Bumblebee and honey bees are supreme affectionate social insects of agricultural crops. Both genus Apis and Bombus are used for the pollination of vegetables, fruits and crops commercially. Honey bee can dispense 80% in insect pollination and considered as a best pollinator towards crop pollination, Bumblebee are more efficient and competent pollinator due to their buzzing behavior, efficiency to forage at low temperature, vibration to burst the pol...

Synergistic and Dichotomous Effects of Nectar Phenolics on Honey Bee Colonies

...e a widespread effect on honey bees and their colonies. Because of their complex, non-linear interactions, it is difficult to assess honey bee health risks from exposure to real-world floral nectar with complex phenolic mixture. In the study, we investigate the bee losses of Apis mellifera in the flowering period of the Mexican sunflower Tithonia diversifolia in southwestern China, and use data mining approach to model the relationships between n...

Effectiveness of Native Solitary Bees in Seed Production of Sesame (Sesamum indicum L.)

Mudssar Ali¹*, Muhammad Awais Ahmad¹, Asif Sajjad² and Shafqat Saeed¹

... effectiveness of native honey bees and solitary bees for better seed production of sesame and future conservation of effective insect pollinators. The sesame crop was grown during two years (2019 & 2020) at the research farm of MNS- University of Agriculture Multan, Pakistan. Abundance and diversity of native insect pollinators, their foraging behavior in terms of visit duration and visitation rate (number of flowers visited per minute) along with their p...
