“…Supplementary pollination by honeybees enhanced the apple yield by 19.43%. The findings are in accordance with previous studies (Partap et al 2017;Dar 2016;Mattu and Raj 2015;Bhagat and Mattu 2013). Partap et al (2017) found that honeybee pollination in the Chitral district of Pakistan increased apple yield by 41.9% in 2014 and 47.9% in 2015.…”

“…The findings are supported also by Partap et al (2017): in the Chitral valley of Pakistan, compared to natural pollination, pollination by Apis mellifera improved apple weight (+35%), shape (+19.9%), colour, and brightness (+17.5%).…”

“…We used the partial budgeting technique to arrive at the comparative economics of managed and nonmanaged apple orchards and estimate the returns on investment in managed pollination services in the apple orchards of Kashmir valley. To quantify the economic value of pollination service provided by honeybees in case of apple, we employed two empirical models: The formulae for pollination service value and pollination welfare implication have been used earlier (Lars Hein 2009;Partap et al 2012Partap et al , 2017Garrat et al 2014a, b).…”

In the Kashmir valley, managed pollination orchards yield 35.22 tons per hectare of apples on average, 19.43% more than the non-managed orchards' yield of 29.49 tons, and the quality of fruit is also better. Pollination services improved the income of managed apple orchards, and its value for apple in the Kashmir valley is estimated at INR 126.56 billion per annum. If managed pollination services are extended to the entire area under the apple crop, an additional pollination welfare implication to the tune of INR 29.71 billion (almost INR 300 crore) will be realized per annum.

“…Unlike apple orchards in other parts of the world (Pardo & Borges 2020;Hutchinson et al 2021), no bumblebee species (Bombus) were recorded as visitors in the orchards surveyed here. Partap et al (2019) reported bumblebees as pollinators in the Hindu Kush-Himalayan Region of India. However, many bumblebee species in Bhutan are likely to be found in very high elevation areas (Williams et al 2010).…”

Apples are one of the most important global crops that relies heavily on insect pollination, which has been shown to increase apple production and value. However, recent reports indicate that apple production has been declining in certain regions, including in Bhutan. One of the potential causes of declining production are pollination deficits driven by a low abundance and diversity of pollinators, a phenomenon that has received little attention in Bhutan to date. Here, we present the first study examining the diversity of flying insects in Bhutanese apple orchards in relation to apple quality. During the apple flowering season, 1,006 insects comprising 44 unique (morpho-)species from the orders Hymenoptera, Diptera, and Lepidoptera were recorded using a standardized method of passive and active trapping within nine different orchards in Thimphu, Paro, and Haa districts, in the western part of Bhutan. During the harvest season, 495 apples were collected from these nine orchards, and we measured five different parameters; weight, size, sugar concentration, seed number, and malformation score. The most dominant flower visitors across all orchards were honey bees (mostly Apis mellifera, followed by A. cerana and A. dorsata). Orchards with a higher abundance of flying insects (both managed and wild) had better apple quality (weight, size and sugar concentration). Contrary to reports from other regions of the world, flower visitor diversity did not correlate with the quality of the apples. This represents the first study reporting on apple pollination in Bhutan and highlights the importance of pollinators and reinforces the need to develop pollinator friendly practices to ensure sustainable apple production.
