The mountain bumblebees of the subgenus Alpigenobombus Skorikov, 1914, are uniquely distinctive because the females have enlarged mandibles with six large, evenly spaced teeth, which they use to bite holes in long-corolla flowers for nectar robbing. Recognition of species in this subgenus has been uncertain, with names used in various combinations....

Bactrocera dorsalis (Hendel, 1912) (Diptera: Tephritidae), commonly known as the oriental fruit fly, is a highly destructive pest that globally infests fruits and vegetables, resulting in significant annual economic losses. Initially detected in Taiwan Island, it has rapidly expanded its distribution range to various regions in mainland China since...

Over a long period of evolution, insects have developed unique intestinal defenses against invasion by foreign microorganisms, including physical defenses and immune responses. The physical defenses of the insect gut consist mainly of the peritrophic matrix (PM) and mucus layer, which are the first barriers to pathogens. Gut microbes also prevent t...

The massive use of synthetic pesticides to manage agricultural pests results in environmental pollution and health hazards. The secondary plant metabolites, which are majorly dominated by terpenoids, have the potential to be developed into novel alternatives to synthetic chemicals. Therefore, in our current investigation, six majorly dominated esse...

Synthetic pesticides are extensively and injudiciously applied to control agriculture and household pests worldwide. Due to their high use, their toxic residues have enormously increased in the agroecosystem in the past several years. They have caused many severe threats to non-target organisms, including humans. Therefore, the complete removal of...

The genus Xylota Meigen is revised from Pakistan and a key to the known species is presented for the first time. Xylota coquilletti Hervé-Bazin, 1914, and X. nursei Brunetti, 1923 are newly recorded for Azad Kashmir, Pakistan. Of these, the former species is a new record for Pakistan. Brief taxonomic notes with diagnostic characters, digital photog...

Species are often presumed to be apparent in nature, but in practice they may be difficult to recognise, especially when viewed across continents rather than within a single site. Coalescent-based Poisson-tree-process (PTP) models applied to fast-evolving genes promise one quantitative criterion for recognising species, complete with the estimates...

This study was conducted during 2017-18 to explore the genus Bombus Latreille, 1802 from the Himalayan region of Pakistan. As a result, we found 771 specimens of bumblebees, among them nine species viz. Bombus asiaticus Morawitz, 1875, B. lucorum subsp. jacobsoni Skorikov, 1912, B. rufofasciatus Smith, 1852, B. tunicatus Smith, 1852, B. kashmirensi...

Survey was conducted in different localities of district Skardu, Gilgit Baltistan during the year of 2016-2017 to record species composition belonging to genus Bombus Latreille 1802. It was discovered that 11 species distributed over 8 subgenera of the family Apidae under subfamily Apinae, tribe Bombini occurring in this region. The subgenera, Alpi...

The Drosicha sp (mealy bug) is an invasive and polyphagus pest in Baltistan, Pakistan. This pest was recorded in 2005, as primary pest of willow tree (Salix wilhelmsiana). The secondary hosts of Drosicha sp was recorded in Skardu region are apricot, apple, cherry, and mulberry. Our study was designed to find out Integrated Pest Management strategie...

PVY, Potato, Myzus persicae, ss RNA, Vector control

Potato virus Y (PVY) is distributed worldwide and is most important plant virus affecting solanaceous crops in particular potato and tomato. PVY cause 10-100% yield loss on potato and 39-75% on tobacco crops worldwide. PVY has different strains which cause variety of symptoms on different parts of the host plant species. Initially three chief strai...

Field investigation was carried out for the control Cabbage looper during July 2015-16, at new developmental farm of the University of Agriculture Peshawar-Pakistan in RCBD arrangements with three treatments i.e. Garlic, Ginger and Tobacco @3.00% extracts. Golden Acre variety of cabbage was grown for investigating cabbage looper infestation as the...

The present investigation was carried out at Skardu Baltistan region during summer 2015 to find out the efficacy of different synthetic chemical insecticides on Potato aphid (M. euphorbiae) and their inauspicious effects on Lacewing in potato field. The field investigation were carried out with seven treatments with different level of Insecticide c...

Abstract A Field Studies were carried out for the control of Tomato fruit borer (Helicoverpa armigera) during July 2014 at District Skardu Baltistan Pakistan. Variety of tomato grown was Shalkot when fruit setting starts in Skardu region we applied chemical insecticide and bio-pesticide at their recommended doses. The aim of investigation is to pro...

Field experiment was conducted at district Skardu Gilgit Baltistan during year 2014 to record the population dynamics, distribution, control measures and natural enemies associated with Drosicha mealybug on Willow tree (Salix wilhelmsiana). Sticky bands and gunny bag wrapping measures were applied in last week of February .Gunny bag wrappings along...
