“…However, mass flowering crops may benefit social honeybees in the landscape by providing food for a large number of larva in colonies (Roubik, ; Westphal et al ., ). Based on personal observations, we also found that flies (order Diptera) were prevalent on mango flowers, consistent with other studies (Singh, ; Dag & Gazit, ; Huda et al ., ; Sritongchuay et al ., ), such that nectar resources may have been significantly reduced for bees by these other visiting insects.…”

1 Global population declines of insect pollinators highlight the need for a greater ecological understanding of the responses of wild pollinators to local management actions and to human alterations of landscapes, especially in the tropics where crops are highly dependent on wild pollinators. 2 We examined the effects of local and landscape factors on the richness and abundance of bees in farms around Bangkok, Thailand. Bee communities in 24 mango (Mangifera indica L.) orchards in heavily modified landscapes (61-99% anthropogenic land cover) were compared. We predicted that bees would be more species rich in orchards with higher flower diversity, whereas small-sized bees with non-eusocial and/or below-ground nesting habits would be more sensitive to human disturbance, and hence rare. 3 Twenty-eight species were caught and individuals of genus Apis comprised >92% of 3842 bees sampled and dominated all 24 sites. 4 Habitat effects on bee richness and abundance were stronger at the farm scale than at the landscape scale. At the farm scale, total bee richness and abundance, as well as small, non-eusocial and below-ground nesting bee richness and abundance, were negatively associated with field size and positively associated with flowering plant diversity. The percentage of urban land cover within a 1-km radius was weakly but positively related to total bee richness and small-sized bee richness; total bee abundance was positively associated with wetland cover. 5 A greater diversity of flowering plants retained in smaller fields maintained higher bee richness and abundances, particularly small-sized bees. Farmers can enhance bee populations by maintaining small patches of flowers in their fields.

“…The addition of floral resources also enhanced the abundance of hoverflies in adjacent blueberry fields. Although hoverflies are not effective pollinators of blueberry, they are efficient pollinators of other crops, such as mango (Dag & Gazit ) and oilseed rape (Jauker & Wolters ), and the larvae of aphidophagous species are also biological control agents of many soft‐bodied arthropods (Bugg et al . ; Smith, Chaney & Bensen ), thus providing an additional ecosystem service to crops.…”

Summary1. Pollination services from wild insects contribute to crop productivity around the world, but are at risk of decline in agricultural landscapes. Using highbush blueberry as a model system, we tested whether wildflower plantings established adjacent to crop fields would increase the abundance of wild pollinators during crop bloom and enhance pollination and yield. 2. Plantings were seeded in 2009 with a mix of 15 perennial wildflower species that provided season-long bloom and increased plant density and floral area during the subsequent 3 years. 3. Honeybees visiting blueberry flowers had similar abundance in enhanced and control fields in all 4 years of this study, whereas wild bee and syrphid abundance increased annually in the fields adjacent to wildflower plantings. 4. Crop pollination parameters including percentage fruit set, berry weight and mature seeds per berry were significantly greater in fields adjacent to wildflower plantings 3 and 4 years after seeding, leading to higher crop yields and with the associated revenue exceeding the cost of wildflower establishment and maintenance. 5. Synthesis and applications. We suggest that provision of forage habitat for bees adjacent to pollinator-dependent crops can conserve wild pollinators in otherwise resource-poor agricultural landscapes. Over time, these plantings can support higher crop yields and bring a return on the initial investment in wildflower seed and planting establishment, also insuring against loss of managed pollinators. Further understanding of the importance of planting size, location and landscape context will be required to effectively implement this practice to support crop pollination.

“…Flowering ranges from February to March, fruit formation occurs in March to April and the fruits mature in June. The mango plant is reported to be attacked by a total of 250 insect and mite species at different growth stages (Babu et al 2001;Sahoo & Jha 2008); however many insects in the order Diptera and Hymenoptera help pollinate this crop (Dag & Gazit 2000).…”

Insect species inventories along with pest prevalence, foraging behavior of pollinators and their effect on fruit set of mango were studied in a mango‐based agroforestry area in Bangladesh during January to June 2013. Of 1751 collected insects, 11 species in five orders and nine families were pests, 13 species in six orders and eight families were predators and eight species belonging to three orders and seven families were found as pollinators. The pests exerted significantly higher abundance but lower diversity than pollinator, predator and other insects. The pollinator richness was found to be lowest but showed higher as well as similar diversity to other category insects. Three pest species prevailed throughout the season and hoppers showed significant abundance. Among the predators, ants were most abundant. Sulphur butterfly and syrphid fly revealed statistically identical and higher abundance than other pollinators. During the flowering season, pests were dominant and the abundance of insects was observed to peak at 11.00 h. The pollinators differed in their landing duration on flowers and their activity led to higher levels of fruit set. This study provides baseline information on insect abundance in an agroforestry system, which stresses the importance of conservation of beneficial insects.
