“…In another study, A. mellifera was the most frequent visitor in different sunflower hybrids (Oz et al, 2009;Hoffman & Chambers, 2006;Kasina et al, 2007;Mallinger & Prasifka, 2017). For the oilseed crops honeybees were found to be abundant in mustard (Brassica juncea: Brassicaceae) (Shakeel et al, 2019;Delaplane et al, 2013;Parbat, 2019), canola Brassica napus: Brassicaceae) (Akhtar et al, 2018;Amro, 2021), and sesame (Sesamum indicum: Pedaliaceae (Das et al, 2019;Pashte et al, 2013). Previous studies from Pakistan indicated A. mellifera as an abundant and efficient pollinator of sunflower (Akhtar et al, 2018;Ali et al, 2015).…”

Sunflower (Helianthus annus L.) is a highly cross-pollinated crop dependent on insect pollinators to provide a good quality edible oil worldwide. Different sunflower hybrids vary in terms of dependence on insect pollinators. Previously few studies have been conducted regarding the role of insect pollinators in hybrid sunflower seed production in Pakistan. Therefore, the current study was planned to explore the abundance and diversity along with foraging behavior (visitation rate and stay time) of native insect pollinators as well as to study the effect of different pollination treatments (free insect visits vs. no insect visits) on the reproductive success of different hybrids of sunflower. Two sunflower hybrids were grown at the research farm of MNS University of Agriculture, Multan, under the Randomized Complete Block Design (RCBD). In our study, the pollinator community consisted of honeybees (Apis dorsata, A. mellifera, and A. florea), solitary bees (Pseudapis sp., Megachilidae sp. and Xylocopa sp.), and syrphid flies (Eristalinus aeneus and E. megacephalus). Furthermore, the relative abundance of pollinators was high in the H4 (having a flat head with 45º head angle from the stem) hybrid, while the least abundance was observed in H3 (180º head angle from stem). H4 proved to be a better hybrid among the hybrids regarding the number of seeds and seed weight. Both bees, i.e., solitary bees and honey bees, are crucial for pollinating sunflower. Comparative results of free insect visits and no insect visit treatments showed that the maximum number of seed weight, number of seeds, and seed diameter was observed in free insect visits compared to no insect visit treatment. Therefore, conserving the diversity of the native insect pollinators will lead to a higher yield of sunflower hybrids and other cross-pollinated crops.

“…Effective pest management strategies, including the use of resistant cultivars, crop rotation, and timely application of pesticides, can help minimize the damage caused by pests and diseases while maintaining high-quality canola grains [106,107]. On the other hand, insect pollination of canola is another crucial factor in increasing its seed yield and quality [108]. Honey bees are the most effective pollinators for canola, as they enhance both self-pollination and cross-pollination.…”

Canola, Brassica napus L., is a major oilseed crop that has various uses in the food, feed, and industrial sectors. It is one of the most widely produced and consumed oilseeds in the world because of its high oil content and favorable fatty acid composition. Canola grains and their derived products, such as canola oil, meal, flour, and bakery products, have a high potential for food applications as they offer various nutritional and functional benefits. However, they are affected by various factors during the production cycle, post-harvest processing, and storage. These factors may compromise their quality and quantity by affecting their chemical composition, physical properties, functional characteristics, and sensory attributes. Therefore, it is important to optimize the production and processing methods of canola grains and their derived products to ensure their safety, stability, and suitability for different food applications. This literature review provides a comprehensive overview of how these factors affect the quality of canola grains and their derived products. The review also suggests future research needs and challenges for enhancing canola quality and its utilization in food.

“…Consequently, information on the dietary needs of honeybees and available pollen-forage plants in our research region must be readily accessible. Honeybees are the most efficient pollinator for enhancing most crop yields in Assiut region, Upper Egypt (Amro, 2021). The main pollen flow seasons in Assiut are citrus (Citrus Spp.)…”

The honeybee venom productivity was evaluated between three honeybee hybrids i.e. Carniolan (Apis mellifera carnica), Buckfast (Apis mellifera buckfast) and Italian (Apis mellifera ligustica) during 2022 summer season in Assiut area, Upper Egypt. Bee venom was extracted from colonies using bee venom collecting equipment with an electronic impulse generator for colony stimulation. The efficiency of three positions of venom collector trap namely, front drawer venom trap (FDVT), bottom brood nest venom trap (BBNVT) and above brood nest venom traps (ABNVT) were evaluated. The Carniolan bees showed a non-significant amount of produced venom compared with Buckfast. However, it showed a highly significant venom amount when compared with the Italian hybrid. The obtained data indicated that in the case of using ABNVT, a significantly high amount of bee venom was collected (2.30, 2.00, 1.78 g/colony/day) followed by FDVT with, (1.97, 1.88, 1.52 g/colony/day) while BBNVT, enables bees to collect the lowest amount of venom (1.03. 0.95, 0.64 g/colony) by Carniolan, Buckfast and Italian honeybee colonies, respectively. The highest amount of bee venom collected during summer season was recorded between 10-20 July and followed by 17-31 August. However, the lowest amount of bee venom collected by the traps was recorded during the first two weeks of September for all tested honeybee hybrids. In conclusion, reliance on Carniolan and Buckfast hybrid bees may meet the requirements of beekeepers to produce satisfied quantities of bee venom with a distinct preference for using pollen traps above the brood nest to enhance venom production.
