Significant variations of bacterial communities among the developmental stages of Scirpophaga incertulas (Walker) (Lepidoptera: Crambidae).

The yellow stemborer, Scirpophaga incertulas, is a monophagous pest of rice, attacking the crop from its vegetative to reproductive stages. Microorganisms are crucial in influencing the insect's life cycle, evolution, and ecology, presenting an avenue for understanding and improving management strategies. Present research employed advanced next-generation sequencing technology to investigate the microbiota of S.

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.

Performance of Trichogramma japonicum under field conditions as a function of the factitious host species used for mass rearing.

Different factitious hosts were used to mass rear Trichogramma japonicum Ashmead in different parts of the globe because thorough details were lacking in both the laboratory and the field. The objective of this study was to compare, parasitoid, T. japonicum reared in different factitious hosts.
