KEYWORDS Lantana camara Lantadenes Allelopathy Hepatotoxic Poisonous ABSTRACTLantana camara is one of the most commonly known noxious weed distributed worldwide. The red flower variety (L. camara var. aculeata) of this weed is mainly toxic and usually prevalent in tropical and sub-tropical countries. Lantana leads to hepatotoxicity, photosensitization and intrahepatic cholestasis almost in all the animals. LA is the main toxic pentacyclic triterpenoid present in this weed. Lantadene toxicity leads to fatty degeneration, bile duct hyperplasia, gall bladder edema, degeneration of parenchymal cells and portal fibrosis observed on histopathological examination. L. camara toxicity causes fluctuation in hematological as well as in biochemical parameters. The management of toxic effects can be achieved by activated charcoal, vaccination and supportive therapy but are not much effective. Besides the harmful effects of this plant, there are some beneficial effects also including antiinflammatory, hepatoprotective action, antitumor action etc. The control of this weed is difficult because of its allelopathic action. Nowadays this plant is used in many recent advanced techniques like phytoremediation of particulate pollution, phytoextraction of heavy metals and many others. Thereby the use of this plant in the field of research can be an effective way to manage this alien weed. As far as the toxicity is concerned it can be prevented by the using conventional therapeutic methods along with immunological, nanotechnological and biotechnological approaches. The aim of this article is to discuss the information regarding its progression, mechanism by which it affect animals, pathological alterations, treatment and what strategies we can opt to get rid of this weed.

Disinfestation of stored wheat grain infested with Rhyzopertha dominica by ozone treatment: process optimization and impact on grain properties

BACKGROUND Ozone is a highly oxidative gas that has a long history of safe use as a disinfectant and sanitizer from producers of pharmaceuticals and many other organic compounds. In the current work, disinfestation of stored wheat grain infested with a common insect, Rhyzopertha dominica, was attempted through ozone (O3) treatment as an alternative to chemical fumigants. RESULTS The optimized treatment conditions for ozone fumigation of stored wheat grain were 12% (w/w) grain moisture, 2.5 g m−3 ozone concentration and 8 h of treatment. The mortality of R. dominica adults, pupae, larvae and eggs was 97, 100, 99 and 100%, respectively. Moisture and protein content of the ozone‐treated wheat was found to be lower as compared to infested wheat. Microstructural changes in the treated samples were clearly visible on scanning electron microscopy images, whereas minimal changes at the molecular level and of rheological parameters were evident based on Fourier transform infrared spectroscopy peak and rheometry data. CONCLUSION Ozone was found to be an effective reagent for disinfestation, aimed at all life stages of R. dominica in stored wheat grain, that leaves no residue behind. Rotational strategies can be applied to obtain increased mortality while maintaining the usability of the grain for different purposes. © 2019 Society of Chemical Industry

RESUMENEl uso indiscriminado de plaguicidas sintéticos en el control de plagas y enfermedades que afectan los cultivos, la salud humana, y el medio ambiente, han conducido a resistencia por parte de insectos y presencia de residuos tóxicos en alimentos. Esto ha propiciado la necesidad de desarrollar enfoques alternativos para el control de especies plaga. En el presente estudio se ha investigado la actividad insecticida del aceite esencial de hojas de Lantana camara sobre el insecto modelo Drosophila melanogaster. Se aisló aceite esencial de las hojas de L. camara utilizando el método de hidrodestilación. El bioensayo se realizó por el método de la OMS para determinación de actividad adulticida contra mosquitos y artrópodos. Diferentes compuestos fueron identificados por análisis de cromatografía de gases -espectrometría de masas. El valor de la CL 50 del aceite fue 0.56 mg cm -2 mientras que el valor de la CL 95 fue 0.96 mg cm -2 sobre Drosophila melanogaster. El rendimiento de aceite esencial de hojas obtenido por hidro-destilación fue 0.022% w/w. El análisis por cromatografía de gases -espectrometría de masas del aceite esencial mostro 66 picos, donde Germacren D (19.29%), B-Cariofileno (14.55%), α-Humuleno (9.51%), Biciclogermacren (8.94%), Germacren B (7.26%) y Terpineno (5.62%) estuvieron presentes en mayores cantidades y contribuyeron con el 56.21% del total de los constituyentes. El aceite esencial de hojas de L. camara mostró actividad adulticida sobre la especie de mosca Drosophila melanogaster y podría ser utilizado para el desarrollo de insecticidas a base de aceite como complementario a los insecticidas sintéticos para el control de moscas causantes de importantes pérdidas económicas.

ABSTRACTThe indiscriminate use of synthetic pesticides in the control of pests and diseases affects crops, human health, and the environment, and lead to insect resistance and the presence of toxic residues in food. Previous generated the need to develop alternative approaches to pest species control. In the present study the insecticidal activity of the essential oil of leaves of Lantana camara on the insect model Drosophila melanogaster has been investigated. Essential oil was isolated from L. camara leaves using the hydro-distillation method. The Bioassay test was performed by the WHO method for the determination of adulticidal activity against mosquitoes and arthropods. Different compounds were identified by gas chromatography -mass spectrometry analysis. The LC50 value of the oil was 0.56 mg cm -2 whereas the value of the LC95 was 0.96 mg cm -2 on Drosophila melanogaster. The yield of leaf essential oil obtained by hydro-distillation was 0.022% w/w. Gas chromatography-mass spectrometry analysis of the essential oil showed 66 peaks, where Germacren D (19.29%), B-Caryophyllene (14.55%), α-Humulene (9.51%), Biciclogermacren (8.94%), Germacren B (7.26%) and Terpinene (5.62%) were present in greater amounts and contributed 5...
