...s and mangos. Artificial pollination is a one of most important cultural practice for improving yield of Date palm due to diocious nature of palm tree. Pollen sources play important role in fruit setting .The growers pollinate the date by using low potency pollen source and get low yield. Present studies were conducted with the aim to explore best pollen sources for maximum fruit set and yield. In this respect, an experiment was conducted during 2012 and 2013 ...

Syrphids were recorded as 12.65 to 13.85 per 250 flowers in 2013 but decreased in year 2014 by 7.82 to 7.88 per 250 flowers and Non-Apis bees was recorded as 6.15 to 7.59 per 250 flowers in 2013 which also decreased and recorded as 5.35 to 5.70 per 250 flowers in year 2014. The results showed the trends of increase in population of ...

Enhanced transient beta glucuronidase (GUS) expression with average frequency of 40.56% was noticed with three days of co-cultivation period while two days of co-cultivation period resulted 24.07% transient GUS expression. Addition of 100 mgL-1 L-cysteine in co-cultivation medium increased the transient transf...

The borer attack started at a very initial stage of the crop and swept down many of the progenies. Only 88 exotic and 7 indigenous progenies showed some resistance. The survived plants, among these progenies, were advanced by self pollination. During autumn 2000, only 9 progenie...

Twelve morphological variables, grouped the population into 6 clusters. Common characters of palm belonging to cluster I are lower weights of fruit, nut and husk with shorter fruit equatorial diameter and shorter internodes. Palms belonging to cluster II have higher ...

Foraging Behavior and Pollination Ecology of Bumble Bee and Honey Bee in Pakistan; A Review
... 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 pollen sac, high speed to flower visitation at lo...

Pollinator community was composed of seven solitary bees species (Nomia oxybeloides, Amegilla sp., Lasioglossum sp., Megachile sp., Xylocopa sp.), two honeybee species (Apis dorsata, A. florea) and two syrphid fly species (Eristalinus aeneus, Ischiodon scutellaris). In both the years, honey bees were more abundant than the solitary bees while the syrphi...
