Studies on the insect pollinators diversity and their relative abundance in Eruca sativa Mill. (Arugula) and Brassica rapa L. (field mustard) was carried out during spring season from February to April consecutively during all the three years of 2016–18. Insect pollinators observed belonged to four orders i.e. Hymenoptera, Diptera, Lepidoptera, and Coleoptera. A total of 20 major species of insect pollinators were recorded. The highest abundance of pollinator species belonged to Hymenoptera. The most prominent insect pollinator species were Apis mellifera followed by other three honey bee species of A. cerana, A. flo-rea, and A. dorsata respectively. Some species of solitary bees were also recorded. From Diptera, four species of syrphid fly and one species from Muscidae family were also recorded. Insect pollinators recorded from order Lepidoptera were Pieris brassicae, Vanessa cardui, and Papilio demoleus. Lady bird beetle Coccinella septempunctata was recorded from Coleoptera order as occasional visitor. It was noticed that E. sativa attracted more insect pollinators than B. rapa which may be attributed to different amount and chemical properties of nectar, with number of pollen grains, and flower canopy of both crops. Further studies are needed to confirm the reasons for higher pollinator visitation to E. sativa than B. rapa through chemical analysis of nectar, amount of pollens, flower physiology and phenology of both crops.

Insect pollinator diversity in southern Punjab, Pakistan
Insect pollinator diversity in four forested ecosystems of southern Punjab, Pakistan2019 •
This study investigated pollinator assemblage diversity and richness in four forested ecosystems of southern Punjab, Pakistan, with different landscape types. Pirowal is situated in the plains of irrigated Punjab, Lal Suhanra is part of a sandy desert ecosystem, Ghazi Ghat is part of the Indus River delta, and Fort Munro is located in dry hilly mountains. A yearlong survey of pollinator populations was carried out in these four forested ecosystems from January to December of 2010. Fortnightly hand netting was performed for collecting flower-visiting insects whereas, pan traps of three colors (white, blue, and yellow) were deployed for collecting the data. A total of 8,812 individuals from two orders (Lepidoptera and Diptera) were observed, including 22 families and 154 species. Bees were the most abundant, with 4,502 individuals, and the most species-rich taxa, with 70 species in five families, followed by flies having 2,509 individuals and 51species in 10 families. Wasps were the least abundant with 1,801 individuals and 33 species in seven families. The assemblage structure of pollinator communities as visualized through rank abundance curves showed that there were many species with low abundance and only a few species with a much higher abundance. The most abundant species among the bees, in order, were Nomia sp.3, Megachile bicolor, and Colletes sp.3; among flies, Syrphus sp.2, Calliphoridae sp.1, and Empididae sp.4; and among wasps, Tiphiidae sp.1, Myzininae sp.2, and Scelionidae sp.1.

Yearlong association of insect pollinator
Yearlong association of insect pollinator, Pseudapis oxybeloides with flowering plants: Planted forest vs. agricultural landscape2019 •
The yearlong association of a native bee, Pseudapis oxybeloides (Halictidae: Hymenoptera) was studied with 72 plant species in a subtropical planted forest and some adjacent agricultural landscapes at Multan, Pakistan. The study resulted in 66 interactions of P. oxybeloides with only 24 plant species in 15 families while other 48 plant species were not visited by this bee. The maximum abundance of P. oxy-beloides (7-9 individuals) was recorded on Achyranthes aspera and Launaea procumbens followed by Ageratum conyzoides, Trianthema portulacastrum and Cleome viscosa (5-6 individuals). Majority (19) of plant species were visited by only 1-4 individuals. The bee activity was started in the month of March which attained its peak in May followed by a gradual decline until September. No bees were observed during the months of January and February. There was a significant positive relationship between bee abundance and number of flowering plant species. Bee abundance had a strong positive relationship with temperature while it had a strong negative relationship with relative humidity (%). Floral abundance increased with the number of flowering plant species while it was not influenced by floral span of plant species. Besides giving the floral host plants of P. oxybeloides, the current study also gives a better understanding of its seasonality along with its relationships with different biotic and abiotic factors under local conditions. These findings can help in maintaining and managing P. oxybeloides population particularly and other native bees in general at local scale.

Diversity and Relative Abundance of Insect Pollinators in Moroccan AgroecosystemsAgroecosystems are often impoverished ecosystems, but they can host diverse communities of insects which provide ecosystem services. Specifically, crops may benefit from insect pollinators that increase their quantity and quality of yields. Basic knowledge is still needed regarding the identity, diversity, abundance, and ecology of insect pollinators in many parts of the world, especially in low and middle-income countries. In this study we investigate the potential of agroecosystems and crops in Morocco to host a high diversity of insect pollinators. We sampled insects in four eco-climatic regions encompassing a total of 22 crops for 2 years (2018–2019). After describing the general pattern of diversity and abundance of insect pollinators, we focused our comparative analyses on bees as they are known to be the most efficient and abundant group of insect pollinators. We recorded a total of 53,361 insect pollinators in all agroecosystems among which 37,091 were visiting crop flowers....

Agricultural fields contain some small plants (weeds) which are known as agrestals. Generally, weeds are perceived as unwanted intruders in agro-ecosystems that compete for resources, reduce yields, and force the use of human labor and technology to prevent crop losses; but not all weeds are undesirable. Some weeds act as valuable agro-ecosystem components. They serve as nutritious foods, and important sources of fodder and medicine. Certain weeds may limit insect damage to crops. These beneficial effects indicate that weeds are not just agricultural pests, but can also play beneficial roles in the human society. So, the main objective of the study is to know about the beneficial agrestals of the district and their roles. Detailed field surveys were made in different blocks of the district to collect data about agrestals and their usefulness. These fields contain various medicinal plants such as Solanum nigrum L., Eclipta prostrata L. Oxalis corniculata L., Rungia pectinata L. etc.,...

Honey production, output, processing, marketing and quality in Adamawa State of Nigeria were studied through survey on four local governments of honey production. There were also physicochemical, microbial and sensory evaluations of samples to evaluate quality. Results showed that about 300 apiarists exist in Adamawa State with volume produced at 12,600 L per annum. Apiarists keep between 1 and 4 hives, harvesting an average of 10 L twice a year. Methods of detecting honey adulteration locally include visual inspection and tongue testing methods. Laboratory evaluations to detect adulteration with caramel or water showed that match-lighting test can detect adulteration with water from 20 % water: honey ratio but could not detect adulteration with caramel. Similarly adulteration up to 70 % with caramel was not detected by panelists. Soluble solids, water and ash ranges were 58.40 to 80.00, 15.60 to 19.20 and 26 to 0.70, respectively. Other parameters were pH (3.80 to 4.50), viscosity ...

Diversity of insect pollinators with reference to their impact on yield production of canola (Brassica napus L.) in Ismailia, Egypt2015 •
A study of insect pollinators and their impact on canola yield was conducted during the 2013/2014 and 2014/2015 growing seasons. The study was carried out at an experimental farm, Faculty of Agriculture, Suez Canal University, Ismailia. The results revealed that 21 species of insect pollinators belonging to 14 families under four orders visited canola flowers. The abundance of Hymenoptera insects reached the maximum of 67.90%, followed by Diptera 14.97%, Coleoptera 13.61%, then Lepidoptera 2.26% as average of both seasons. In open pollination, Colletes lacunatus had the maximum percent abundance in the two seasons (30.45 and 29.34%, respectively) followed by Apis mellifera (12.34 and 17.73%, respectively), compared to other bees and different pollinators. Peaks of foraging activity of both C. lacunatus and A. mellifera were mainly observed from 1:00 to 3:00 pm and they corresponded to the number of flowering plants. Open pollination increased the number of pods per plant, seeds per ...

(2023) Bemerkungen zur Entstehung und Entwicklung von Felix Jacobys Projekt zur fragmentarischen antiken Geographie aus unveröffentlichtem Material des Nachlasses von Friedrich Gisinger.Remarks on the genesis and development of Felix Jacoby’s project on fragmentary ancient geography, based on unpublished documents of Friedrich Gisinger’s Archive · Jacoby’s need to provide a new collection of the fragments of both the historians and of the Greek geographers did not conceal the difficulty of such a huge work and we can assume that the difficulties of this work had appeared early to Jacoby, who had given already in the early twenties, the fifth section to Friedrich Gisinger. The scholarly relationship between Jacoby and Gisinger can be reconstruct- ed on the basis of Gisinger’ s Archive, which is preserved in the Bavarian State Library in Mu- nich. The documents show that there was a kind and intensive collaboration between the two scholars that lasted almost thirty years. Gisinger’ s selection of ancient authors was repeatedly criticized by Jacoby, who was not of the opinion to include also geographical references, f. e. to epic poetry and tragedy. In my study I am focusing on this discussion and its significance for the study of the historical geography of the ancient world.
