The pollination services provided by wild insect fauna in peach depends on many factors, among them the diverse landscapes and habitat diversity is of immense importance contributing to foraging characteristics and hourly visitation frequencies. A considerable variation existed in visitation rate; total visits, percent visitation and total time spe...

Honey bees visit the flowers for two essential nutritional requirements, viz., pollen and nectar. Sometimes the foraging bees collect more nectar, whereas at other times they collect more pollen. What makes them take such decisions has been the interest of many honey bee scientists. The objective of this article was to find out about the drivers ca...
Entomophilous plants have evolved colorful floral displays to attract flower visitors to achieve pollination. Although many insects possess innate preferences for certain colors, the underlying proximate and ultimate causes for this behavior are still not well understood. It has been hypothesized that the floral rewards, e.g., sugar content, of pla...
Climate warming can precipitate mismatches in plant-pollinator interactions by altering their phenologies of both parties, impacting ecosystem services. While most studies have focused on long-term, seasonal phenological shifts, the effect of warming on short-term phenological match-mismatch in these interactions remains unclear. Here, we investiga...
The influence of potential insect pollinators is decisive in the fruiting process of many cross-pollinated plants. The aim of this study was to determine the behaviour of potential pollinating insects visiting Moringa oleifera flowers. Collections were carried out from July to September 2018 and 2019, followed by monitoring of the behavior of poten...
Many Loasaceae are characterized by specialized androecium composed of complex nectar scales and bundles of fertile stamens that present pollen through one-by-one stamen movements to the flower center over several days. It is a challenge for pollen-seeking bees to predict when the small pollen packets will be presented during the days-long staminat...

... Insects belonging to apidae family including honey bees and Xylocopa sp. regarded as the most important and dominant commercial pollinators (<90 per cent), although other bee species like alkali bees (Nomia), leafcutter bees (Megachilidae) and bumble bees (Bombus) also helps in pollination (Dar et al., 2020) [4] . Despite the pollinators, there are huge diversity of insect-pests and mites found on peach trees, causing damage to the bloom, fruits, twigs, limbs, and trunk. ...

Arthropods play very crucial roles in maintaining productive and healthy orchard ecosystem. The diverse fauna of arthropods which inhibit the ecosystem of peach orchard include pests, natural enemies and pollinators. In our study, we assessed the biodiversity and abundance of arthropods visitors in peach orchard. Different methods including sweep nets, visual searching methods, yellow sticky traps and pheromone traps at fortnight interval resulted in a total of twenty species of arthropods collection. Among them, pollinators including eight species constituted a large proportion of arthropods followed by four species of each group viz. arachnids, insect-pests and natural enemies. Among pollinators apidae family showed maximum relative abundance (82%) followed by syrphidae (10%) and halicitdae (8%). The relative abundance was highest in Apis mellifera (21.74%) followed by A. cerana (17.36%) and lowest relative abundance was observed in Xylocopa fenestrata (6.85%). All the pollinator species were most active at 1200h of the day in comparison to 1600h and 0800h. In case of pests, Myzus persicae (47.11%) was the most abundant insect while among arachnids Tetranychus urticae (7.81%) was the most prominent mite that attacks the peach trees. Among natural enemies, Coccinella septumpunctata (7.98%) was the most dominant insect. Maximum mean abundance of all the pests and natural enemies were observed during the months of April to June and that of pollinators were observed during peak flowering season February-March. Our data on abundance and diversity of arthropods will help in efficient management of pests without causing considerable damage to beneficial insects.
... Como resultado de estas adaptaciones, la flor del durazno es visitada por diversas especies de abejas, entre las cuales, se reportan los géneros Bombus, Ceratina, Xylocopa, Lassioglossum, Nomia y Osmia (Dar et al. 2020;Maryam et al. 2020). De ellas, las abejas de los géneros Bombus y Osmia son utilizadas como polinizadores gestionados en cultivos de durazno bajo invernadero, en Asia (Zhang et al. 2019); sin embargo, a nivel general, se reconoce a la especie de abeja Apis mellifera, como el polinizador más importante del duraznero (Randhawa et al. 1963). ...
Diversos estudios demuestran que la inclusión de polinizadores, como las abejas Apis mellifera, generan efectos positivos sobre la productividad de cultivos de durazno (Prunus persica). Esto lleva a probar metodologías que estimulen a las abejas para visitar, con mayor frecuencia, el cultivo de interés, sugiriendo el uso de la técnica de osmoguiado, como herramienta para potencializar el efecto de la polinización. Este estudio valoró un protocolo de osmoguiado, para estimular híbridos africanizados de Apis mellifera, a recolectar polen de flores de durazno, utilizando, como indicador indirecto, el análisis palinológico en muestras de polen. Los tratamientos utilizados fueron con osmoguiado y sin osmoguiado. Cada tratamiento contó con tres colmenas y el periodo de evaluación fue de cinco semanas, coincidiendo con el mayor periodo de floración del durazno. Los resultados evidenciaron que este protocolo no logró estimular a las abejas a visitar la flor de durazno para la búsqueda de polen. La disponibilidad permanente de otras plantas productoras de polen, reportadas previamente como importantes en el aporte de este recurso, pudo influir en la selección de fuentes por parte de las abejas. El polen obtenido provino, principalmente, de plantas de las familias Fabaceae, Asteraceae, Malvaceae y Passifloraceae.
The current studies were done on foraging behaviour and frequency of various Apis species on the parental lines of Rapeseed flowers Brassica napus fields during the time period from April-June of years 2018-2019. The Brassica napus were grown for the purpose of seed production and the pollination efficiency and behaviour of various Apidae were determined. Data revealed that Apis cerana showed higher visitation (No.visits/minute), followed by A. mellifera and A. dorsata. Whileas, the foraging rate of A. florea was significantly low. During the experiment it was found that there was no significant difference between foraging frequency of A. cerana and that of A. mellifera, and the two species were efficient pollinators as far as foraging frequency on rapeseed mustard was concerned, as foraging rate is one of the important factors to determine pollinating efficiency of insect visitors. During the studies we found that foraging rate of all the species of bees was higher on Brassica napus flowers. Therefore, the current study will help to maintain an efficient and economic hybrid seed production programme in case of B. napus.
