Fall armyworm (FAW; Spodoptera frugiperda (J.E. Smith)) is emerging as the most destructive pest of maize in India since its report May 2018.Its rapid spread to more than 90% maize-growing areas diverse agro-ecologies within a span 16 months presents major challenge smallholder farmers, maize-based industry, well food and nutritional security.FAW has been reported from other crops like sorghum millets with varied proportion economic damage.In this review, transboundary movement FAW, role...
The occurrence of Spodoptera frugiperda (J.E. Smith) in Asia was reported for the first time from Karnataka 2018. This pest is widely distributed India, causing significant damage to maize. Management this recent invasive maize-growing regions India relies on chemical control. Resistance greatest obstacle successful use insecticides control pest. Indiscriminate destroys beneficial natural enemies, therefore effective and sustainable alternative strategies are needed. In case, biological...
Abstract In this study, morphological and molecular features were used to identify a new Steinernema sp. from Kerala, India. Morphological provide evidence for placing the species into longicaudum clade. The is characterized by following features: infective juveniles with body length of 1067 μm (914–1268 μm); distance anterior end excretory pore 82 (73–92 nerve ring 105 (91–118 μm). distinguishing feature S. keralense n. presence seven ridges in mid-body region, while all other classified...
Abstract Background The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a highly polyphagous and destructive pest of maize other cereal crops. Biological control potential alternative to chemical insecticides used for the management FAW in maize. Egg parasitoids are promising biocontrol agents as they kill insect at their egg stage before it hatches, thus preventing damaging larval stage. Trichogramma widely augmentative biological native invaded regions....
Summary A new species of entomopathogenic nematode, Steinernema indicum n. sp., was isolated from a coconut palm ( Cocos nucifera ) field in the district Udupi, Karnataka, India. The infective juveniles (IJ) S. sp. possess body length 1043 (869-1172) μ m. lateral fields are formed by eight equally spaced and developed ridges (nine incisures) mid-body region, giving formula 3, 8, 7, 5. excretory pore is located posterior to mid-pharynx region (D% = 63), hyaline occupies ca half tail length....
Rice is capable of taking up both nitrate (NO 3 − ) and ammonical (NH 4 + forms nitrogen (N). It largely grown under flooded cultivation when NH the main form available soil N. The root knot nematode, Meloidogyne graminicola , can cause serious damage to rice crops disturb N uptake translocation. We have investigated if supply influence susceptibility this important pest. Roots supplied with a 100-fold lower calcium (0.1 mM Ca(NO 2 showed higher level nematode infection as measured by gall...
Abstract The Oriental armyworm, Mythimna separata Walker (Lepidoptera: Noctuidae) is a major pest of cereal crops, and its outbreaks result in complete crop loss. In this study, we tested the pathogenicity reproductive potential indigenous entomopathogenic nematodes (EPNs), Heterorhabditis indica Poinar, Karunakar, & David NBAIIH38, Steinernema abbasi Elawad NBAIISa01, S. carpocapsae Weiser NBAIISc05 siamkayai Stock, Somsook Reid NBAIRS92 against larval pupal stages M. under laboratory...
Abstract The potato tuber moth, Phthorimaea operculella (Zeller), is a serious pest of and other commercial crops belonging to the Solanaceae family. In recent years, it has become an emerging problem in potato-growing regions Nilgiri hills southern India. It responsible for reduced quality quantity marketable potatoes. this regard, development eco-friendly control method management moth urgently required. Therefore, present study, virulence Steinernema cholashanense CPRSUS01 originally...
Abstract In this study, morphological and molecular features were used to identify a new Steinernema sp. from Chhattisgarh, India. Morphological provide evidence for placing the species into “ bicornutum” clade. The is characterized by following features: infective juveniles with body length of 587 (494–671) μm; distance anterior end excretory pore 46 (43–50) nerve ring 72 μm (61–85 μm); E % 88 (77–97). first-generation males are characterised 27 genital papillae very short spicules, 61...
Global pesticide usage is 3.5 million tonnes at an average of 1.81kg/ha, while Indian 55,000 metric (2023) with 0.517kg/ha. Compared to the market, biopesticide market remains small- cumulative annual production 9000 and a growth rate 3-5% in consumption which projected reach CGR 8-10% by 2030. The utilization biopesticides amounts approximately 9% overall use increase 50% total 2050. Among several microbial biocontrol agents, Entomopathogenic Nematodes (EPN) has been realised be dependable...
The gram pod borer, Helicoverpa armigera (Lepidoptera: Noctuidae) is considered as a key pest of pigeonpea and also major polyphagous several agricultural horticultural crops in India. Combining chemical insecticides with Entomopathogenic Nematodes (EPNs) could be an effective alternative to reduce the use harmful chemicals. Experiments were conducted determine compatibility Steinernema carpocapsae Heterorhabditis indica registered used for H. control pigeon pea, under laboratory conditions....
A field trial was conducted in a farmer's by integrating biocontrol agents, multiple insecticide tolerant strain (MITs), Trichogramma chilonis and formulation of Bacillus thuringiensis (NBAIR BtG4) with reduced insecticidal spray as biocontrol-based IPM compared to application practice, for the management diamondback moth (DBM), Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae) infesting cabbage. Six T. releases 100,000 parasitized eggs ha− 1 were applied. Along parasitoid release,...
The root-knot nematode, Meloidogyne graminicola , is a serious pest of rice known to reduce grain yield. effects series infestation levels M. on the nutritional and seed quality parameters have been studied under pot field conditions using two cultivars rice, basmati, cv. Pusa Sugandh-5 non-basmati, Pusa-44. 1000 weight was significantly reduced by as much 44.5% in 50.7% Pusa-44 when parent plants were grown soil with very high infestation. protein amylose contents grains both cultivars....
Holotrichia consanguinea is a serious pest of peanut and sugarcane that attacks other commercial crops in India. The efficacy two species entomopathogenic nematodes (EPN), Steinernema abbasi Heterorhabditis indica , against H. was tested under laboratory field conditions. In assay, caused significantly greater mortality (25-100%) than S. (20-80%) second instars 17.5-82.5% third-instar grub larvae, while (10-60%) mortality. These results revealed second-instar grubs were more susceptible EPN...
Three experiments were conducted to compare the attraction and repulsion of second-stage juveniles (J2) root-knot nematode, Meloidogyne graminicola , rice plants supplied with different forms nitrogen. The hydroponically grown in a full nutrient solution containing concentrations (0.1 or 10.0 mM) nitrate (NO 3 − ) nitrogen supply (2.85 mM calcium (Ca(NO 2 ), ammonium (NH 4 NO chloride Cl)) for weeks. Five placed their roots one corner Perspex X Y-chamber partly filled agar J2 inoculated onto...
