Prealighting and Postalighting Volatile Organic Compounds Emitted by Rice Influence the Behavior of .

Yellow stem borer (YSB), , is a major rice pest causing significant yield losses worldwide. We investigated how volatile organic compounds (VOCs) released by the rice variety TN1, both before and after infestation, as well as by its companion weeds, and , influence the behavior of YSB in host selection, recognition, and establishment. Olfactometry bioassays showed that uninfested TN1 plant VOCs attracted YSB more than those from YSB-infested rice plants and weeds.

Volatolomics to Decrypt the Monophagous Nature of a Rice Pest, Scirpophaga Incertulas (Walker).

Scirpophaga incertulas Walker (Lepidoptera: Crambidae, yellow stem borer, YSB) is a monophagous insect pest that causes significant yield loss in rice (Oryza staiva L.). Semiochemical based pest management is being sought as an alternate to chemical pesticides to reduce pesticide footprints.

Distribution and risk assessment of pesticide pollution in small streams adjoining paddy fields.

The present investigation was planned to bridge the knowledge gap on spatiotemporal variations of pesticide pollution in small streams adjacent to paddy fields, and to visualize the associated risks in the aquatic ecosystems. We screened 106 pesticides using GCMSMS and LCMSMS from 10 small streams (n = 212, surface water samples) adjacent to paddy fields over seven months. Fifty-five pesticides were detected across different streams and months.

Facile synthesis of novel magnesium oxide nanoparticles for pesticide sorption from water.

The quantum of pesticides in surface as well as drinking water has become a serious health hazard. In this experiment, magnesium oxide nanoparticles (MgO NPs) were synthesized using leaves of purple-colored rice variety (Crossa) and utilized for simultaneous removal of three pesticides, namely, thiamethoxam, chlorpyriphos, and fenpropathrin from water. The biogenic MgO NPs were characterized using SEM-EDX, FTIR, XRD, DLS, etc.

Sublethal phosphine fumigation induces transgenerational hormesis in a factitious host, Corcyra cephalonica.

Background: The rice moth, Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae) is a pest of stored grains and widely used as a factitious host during the mass rearing of several natural enemies of crop pests. Hormesis is well-documented in pest insects, to some extent in natural enemies of pests.

Results: We report transgenerational stimulatory effects of the widely used fumigant, phosphine.

Functional response of an egg parasitoid, Trichogramma chilonis Ishii to sublethal imidacloprid exposure.

Background: The effectiveness of a biological control agent depends on how well it can control pests and how compatible it is with pesticides. Therefore, we reported the multigenerational effect of a commonly used insecticide, imidacloprid, on the functional response of a widely acclaimed egg parasitoid, Trichogramma chilonis Ishii, to different densities of the host Corcyra cephalonica Stainton eggs. The study investigated the outcomes of the median lethal concentration (LC ) and sublethal concentrations (LC , LC ), along with control treatments for five continuous generations (F to F ).

Genome Organization and Comparative Evolutionary Mitochondriomics of Brown Planthopper, Biotype 4 Using Next Generation Sequencing (NGS).

is the main rice pest in India. Until now, the Indian mitochondrial genome has not been sequenced, which is a very important basis for population genetics and phylogenetic evolution studies. An attempt was made to sequence two examples of the whole mitochondrial genome of biotype 4 from the Indian population for the first time.

Residue dynamics and bio-efficacy of triflumezopyrim against Nilaparvata lugens and non-targeted effect on natural enemies in a rice ecosystem.

Triflumezopyrim (TMP), a mesoionic insecticide, is commonly used for controlling planthoppers in rice. However, the relationship between the TMP residue and toxicity against brown planthoppers (BPHs) has not been studied in detail. We are reporting the dissipation of TMP from rice plant and soil under field conditions.

Entomopathogenic Potential of Native Strain in Suppressing Invasive Whitefly, Martin (Hemiptera: Aleyrodidae), Infesting Coconut.

In 2016, infestation of an exotic polyphagous pest, the rugose spiraling whitefly (RSW), Martin (Hemiptera: Aleyrodidae), was documented on coconut for the first time in India. Instantaneously, RSW has garnered wide attention owing to its damage severity and rapid spread across the coconut-growing regions of the country. Hence, an attempt was made to devise a sustainable integrated pest management (IPM) module using biological control agents as a mainstay component.

Deciphering the associated risk on soil microbes upon use of biopesticides in rice ecosystem.

Plant species, viz Cleistanthus collinus, Lantana camara, and Strychnos nux-vomica are being traditionally used for pest management in rice. However, limited investigation has been carried out to understand the toxic effect of these materials on soil microbes. Hot water extracts of these plants were evaluated for their effects on soil microbial population and enzyme activities along with neem oil and chlorpyrifos as check.

Toxicological effect of underutilized plant, Cleistanthus collinus leaf extracts against two major stored grain pests, the rice weevil, Sitophilus oryzae and red flour beetle, Tribolium castaneum.

Toxicity and repellency activity of Cleistanthus collinus (Roxb.) (CC) leaf extracts were evaluated against rice weevil, Sitophilus oryzae (L.) and red flour beetle, Tribolium castaneum (Herbst) under laboratory condition.
