Abstract:

Rice is an essential cereal crop and serves as the primary food source for the majority of people worldwide. It faces significant challenges from various abiotic and biotic stress factors, with insect pests being a major concern. An experiment was conducted during kharif (June–October), 2019 at Regional Agricultural Research Station (RARS), Karjat, Maharashtra, to study how abiotic factors affect the prevalence of leaf folders and caseworms in rice ecosystems. The results showed that the initial detection of rice leaf folders and caseworms occurred during the 31st Standard Meteorological Week

Kharif and Rabi rice grown extensively over Kerala is mainly infested by gall midge, leaf folder and green jassid in kharif season. Under favourable weather conditions leaf folder become the dreaded pest and cause considerable damage to the crop. The study revealed that maximum and minimum temperature, morning and afternoon relative humidity and weekly total of rainfall have profound effect on the development of leaf folder at their successive generations on kharif rice crop. Weather based multiple regression models for the peak infestation period for each of the generations of the pest were d

Abstract:

Rice plant is attacked by many insect-pests of which yellow stem borer (dead heart at vegetative stage and white ear head at reproductive stage) and leaf folder are considered as prime devastator, responsible for major economic loss. To combat this problem, resistant varieties of rice are required for better production as well as better productivity. Host plant resistance is very much effective in integrated pest management (IPM) system, where negligible pesticidal hazard is present as well as environmental safety, low cost farming by without or minimum pesticide application and proper identif

Abstract:

Rice leaf folders are the major insect pests of rice crops. Insecticides are used by farmers to reduce the yield loss caused by rice leaf folders, but there are hundreds of insecticides available on the Cambodian market, which makes choosing the right insecticide difficult. This experiment was conducted (1) to determine the variation of a population of rice leaf folders in six treatments: control and using insecticide treatments, and (2) to determine the type of insecticide that is effective. The treatments were tested on field plots (5m x 4m). There are six treatments, and each treatment was

The rice leaf folder Cnaphalocrocis medinalis, Guen. is one of the major pests affecting rice. The use of neem products viz. neem seed kernel extract (NSKE) 5% and neem oil (NO) 3% is the available non-chemical method for the management of this pest. A study was carried out at Tamil Nadu Rice Research Institute, Aduthurai during 199395 to enhance the effectiveness of this product. Combinations of seed oil viz. pungam (Karanj), illuppai, sesame, castor and mustard at 1% with NSKE 4% and NO 2% were tested for their efficacy against leaf folder under laboratory, glass house and field conditions.

The egg masses of yellow stem borer, larvae of leaf folder and rice horned caterpillar and eggs of ear head bug were collected randomly at fortnightly interval from four different varieties viz., CO 43, CO 50, CO 51 and CR 1009 from the rice field. The data was pooled and per cent parasitization was calculated to find out the varietal preference and seasonal variations of parasitoids. Among the four different varieties tested for the preference of parasitoids, per cent parasitization of stem borer egg mass was found to be more (26.59) in CO 50. The per cent parasitization of leaf folder larvae

Abstract:

Interactions between plants and insect herbivores are important determinants of plant productivity in cultivated and natural agricultural fields. The rice leaf folder (Cnaphalocrocis medinalis) causes tremendous damage to rice production in Asian countries. However, little information is available about how rice plants defend themselves against this destructive pest at molecular and biochemical levels. Here, we observed the transcriptomic and metabolomic differences in rice leaves after 0, 1, 6, 12, and 24 h of being fed by C. medinalis using RNA sequencing and metabolome profiling. Transcript

ABSTRACT Experiments were carried out in field conditions to analyse the effect of induced resistance on certain major pests of rice viz., leaf folder, stem borer and gall midge. The population of these insects were assessed at regular intervals on plants imposed with treatments including neem cake (NC),farm yard manure (FYM), Azospirillum (Azos), phosphobacterium (Phos), Silicate Solublising Bacteria (SSB) and lignite fly ash(LFA).The results revealed that the combination of FYM, three biofertilizers, lignite fly ash and neem cake applied in splits significantly reduced the incidence leaf fol

Abstract:

The potential yield loss of 15-25% rice production is noticed due to different pest infestation in South Asian countries. This is due to the favorable climatic conditions for pests. It compels farmers to use a major chunk of pesticides to prevent/recover from pest attack. Hence, the field experiments were carried out to test the insecticide, Chlorantraniliprole 625 g/L FS as seed treatment formulation. It is evident from the studies undertaken during rabi 2018-19 and kharif 2018, that Chlorantraniliprole provided excellent control over yellow stem borer and leaf folder in conventional variety

Abstract:

Spraying monocrotophos (Nuvacron) 36 SUC @ 500 ml/ha on need basis was found to be the most effective in keeping the rice leaf folder infestation below ET level as well as in giving highest grain yield with maximum net profits. Quinalphos (Ekalux) 25 EC and phosalons (Zolone) 35 EC ranked second in order of efficacy. Performance of chlorpyriphos (Coraban) 20 EC and phosphamidon (Dimecron) 85 SC was moderate, while fenitrothion, dichlorvos, fenthion and carbaryl were not very effective.

Although we know that adult of this insect can migrate to avoid heat stress, the behavioral response of larva to high temperature is still unclear. Therefore, impacts of high temperature on behavioral traits ofC. medinalisincluding host choice, settling and folding leaf were observed. The results revealed that these behavioral traits were clearly influenced by high temperature. The larvae preferred maize leaves rather than rice and whe
