Several management approaches were evaluated against pod borer attacking yard long bean during April - July, 2019 at Entomology Research Field, Bangladesh Agricultural Institute (BARI), Gazipur. The package namely sanitation + spraying bio-pesticide Antario (Package 1), Spinosad 45 SC 3) and alternate of 45SC 4) showed almost equal effectiveness in reducing flower damage by higher yield. But th...
The tomato plant (Solanum lycopersicum Mill.) is sensitive to cold, and low field temperatures can result in shortened growth periods and decreased crop yield. Transcription of CRT/DRE-binding factor (CBF) is regulated by INDUCER of CBF EXPRESSION1 (ICE1). CBF activates many downstream genes that confer cold tolerance on plants. ICE1 has been used in genetic engineering to improve cold-resistan...
Few quantitative trait loci have been mapped for resistance to Pseudomonas syringae pv. phaseolicola in common bean. Two F₂ populations were developed from the host differential UI3 cultivar. The objective of this study was to further characterize the resistance to races 1, 5, 7 and 9 of Psp included in UI3. Using a QTL mapping approach, 16 and 11 main-effect QTLs for pod and primary leaf resis...
The legume pod borer, Maruca vitrata (Lepidoptera: Crambidae), is an insect pest species of crops grown by subsistence farmers in tropical regions of Africa. We present the de novo assembly of 3729 contigs from 454- and Sanger-derived sequencing reads for midgut, salivary, and whole adult tissues of this non-model species. Functional annotation predicted that 1320 M. vitrata protein coding gene...
The European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae), is a major pest of corn, Zea mays L., in North America, Europe and Asia. Before the introduction of transgenic Bt corn targeting lepidopteran pests, the European corn borer was responsible for over $1 billion in damage and control measures annually in the U.S. alone (Mason et al. 1996). Management of this insect historically ...
Background: The spotted pod borer (SPB), Maruca vitrata Fabricius is a key insect pest of major legume crop i.e. pigeonpea, Cajanus cajan in India and semi-arid tropics. Identifying SPB resistant genotype will help sustainable management attaining nutritional security. has developed insecticide resistance to most the chemical like Organophosphorous group insecticides also it expanding its geogr...
An experiment was conducted during kharif season of 2022-2023 to evaluate the cost benefit ratio by using different insecticidal applications viz., Chlorantraniliprole 18.5 SC (0.5ml/l), Spinosad 45 (0.4ml/l), Nisco sixer plus (2ml/l), Bacillus thuringiensis 4% WSP (2gm/l), Beauveria bassiana 1.15% WP (5gm/l), Neem oil @2% (5ml/l), ½ dose + (2.25ml/l) and Control plot against gram pod borer, He...
Wild relatives continue to evolve in nature, and live by a different rule than the crop plants – which is survival of the fittest. Wild species have evolved to survive droughts, floods, extremes of heat and cold, and have the capability to withstand damage by insect pests and diseases that cause heavy damage to cultivated species. Many improved cultivars of crops are vulnerable to insect pests ...
Two candidate diagnostic concentrations of the Cry1Ab and Cry1Ac toxins from Bacillus thuringiensis corresponding to the LC99 and EC99 (effective concentration that causes 99% growth inhibition) for European corn borer, Ostrinia nubilalis (Hübner), were determined based on previously obtained baseline data. Validation experiments using field-collected European corn borer populations from across...
