The global losses due to insect pests have declined from 13.6% in post-green revolution era 10.8% towards the beginning of this century. In India, crop 23.3% 15.7% at present. terms monetary value, Indian agriculture currently suffers an annual loss about US$ 36 billion. last two decades witnessed a remarkable progress various biopesticide strategies including development transgenic crops. Such should be utilized integrated pest management programs reduce without affecting quality environment.
Abstract The whitefly, Bemisia tabaci is a cryptic species complex in which one member, Middle East-Asia Minor 1 (MEAM1) has invaded globally. After invading large countries like Australia, China, and the USA, MEAM1 spread rapidly across each country. In contrast, our analysis of India showed very different pattern. Despite detection being contemporaneous with invasions not widely instead remains restricted to southern regions. An assessment Indian genetic diversity level equivalent that...
Bees use sun’s position for navigation and thus a solar eclipse may affect this capability. Present study was conducted during partial on June 21, 2020 at Ludhiana, Punjab. Apis mellifera L foragers’ activity the hive entrance recorded through digital bee counter. Bees’ increased normally, i.e. 771 823 bees/ 15 mins coming in going out of hive, respectively before start eclipsephase. At peak obscuration it decreased slightly but non-significantly. Changes temperature andhumidity might have...
Armyworm, Mythimna separata (Walker) is considered as serious pest of sorghum, millets, rice, maize and wheat in Asia Australia. The genetic diversity M. collected from four locations Punjab viz. Amritsar (Attari), Jalandhar (Kartarpur), Gurdaspur Bathinda districts was studied. DNA barcode region (mtCOI) samples these cloned sequenced. Multiple alignment all sequences revealed only one substitution “T” instead “C” at 364th position samples. population Amritsar, were genetically similar...
Bees are the important natural resources, play a crucial role in maintaining diversity and sustaining food security. In past couple of years, these tiny animals facing problems due to various factors like climate change, loss habitat, bee pasturage, reduced immunity, pesticide poisoning, etc. Among these, insecticides, particularly ones belonging class neonicotinoids have been blamed worldwide. Thiamethoxam is one among insecticides this group. It systemic insecticide whose residues reported...
Diversity and abundance of bees were estimated in six agro-climatic regions an intensive agricultural state India i.e. Punjab during the year 2020-21. Random sampling was done at various locations all regions. Thirty sweeps hand insect net made each location. Overall, 7482 bees’ specimens collected among which most abundant bee species Apis mellifera Linnaeus (12.58%), followed by dorsata Fabricius (12.24%), cerana (11.61%) florea (9.18%). The highly diverse with respect to number their...
Abstract Background: In the quest to identify new resistance genes analogous those found in other plant species, a novel primer designing strategy is introduced for first time. Unlike traditional methods that rely on prior information about degeneracy positions, this approach involves primers based specific domain positions within candidate gene and eliminates need knowledge of degeneracy. By using approach, it becomes possible uncover understand their functional interactions with pathogens....
DNA barcoding using cytochrome c oxidase I (mtCO1) for molecular characterization is a taxonomic method that uses short genetic marker in an insect to identify species, including unknown species. The coming-to-light of this identification tool timely when we are facing perhaps the greatest rate species loss recent millennia. This study contributes increasing number published accounts and accurately distinguishing pollinator fauna cotton Punjab, India. mtCOI region all samples was amplified,...
The citrus leaf miner populations were collected from nursery in Gurdaspur and Abohar regions of Punjab. mitochondrial cytochrome oxidase I (mtCOI) gene was amplifed using specifc primers, cloned nucleotide sequence determined. Both identifed as Phyllocnistis citrella based on 99 to 100 per cent homology BLASTn. multiple alignments both the sequences revealed only one substitution “C” instead “T” at 499th position population. Nineteen mtCOI (USA:15, Spain:2, Japan:2) downloaded NCBI...
