Sorghum Resistance to the Rice Weevil, Sitophilus oryzae (L.): Antixenosis [PDF]

International Journal of Tropical Insect Science, 2002
Thirty-five grain sorghum genotypes representing 6 variable groups (A/B-lines, R-lines, commercial varieties, germplasms, mutants and locals) were evaluated for the orientation, colonisation and oviposition responses of the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), governing the antixenosis component of resistance. In free-choice

Investigation of Insect Resistance Components in Wild Pigeonpea Cajanus Scarabaeoides

Proceedings, 2019
Cajanus scarabaeoides (L.) Thouars is the closest wild relative of cultivated pigeonpea, Cajanus cajan (L.) Millspaugh. However, unlike cultivated pigeonpea which is very susceptible to insects, especially Helicoverpa armigera (Hubner), this wild ...

Resistance of Rice Varieties to \u3ci\u3eSitophilus oryzae\u3c/i\u3e (Coleoptera: Curculionidae) [PDF]

, 2016
Rice, Oryza sativa L. (Poaceae), is one of the world’s most important food crops. Among the insects that damage rice grains, the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), is the most important species.

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

Entomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 236-250, March 2026.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

Mechanisms of Oryza sativa (Poaceae) resistance to Tagosodes orizicolus (Homoptera: Delphacidae) under greenhouse condition in Venezuela

Revista de Biología Tropical, 2012
Tagosodes orizicolus is one of the main plagues of rice in tropical America causing two types of damages, the direct one, feeding and oviposition effect, and an indirect one, by the transmission of the “Rice hoja blanca virus”.

Characteristics of Chili (Capsicum annuum L.) That Are Resistant and Susceptible to Oriental Fruit Fly (Bactrocera dorsalis Hendel) Infestation

Horticulturae, 2022
The response of chili (Capsicum annuum L.) to oriental fruit fly infestation (Bactrocera dorsalis) is highly variable among varieties. The differences in the resistance level of chili to oriental fruit fly infestation are presumed to be determined by the

Levels of Tolerance, Antibiosis, and Antixenosis Among Resistant Buffalograsses and Zoysiagrasses

Journal of Economic Entomology, 2008
The western chinch bug, Blissus occiduus Barber, has been documented as one of the most serious pests of buffalograss, Buchloë dactyloides (Nuttall) Engelmann, and zoysiagrass, Zoysia japonica Steudel, grown for turf in midwestern states. Resistance to the western chinch bug has been identified in both buffalograsses and zoysiagrasses.

Molecular and Structural Characterization of Foam Proteins from Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) Nymphs Reveals Adaptive Features and Potential Targets for Pest Control

Archives of Insect Biochemistry and Physiology, Volume 121, Issue 2, February 2026.
Nymphs of Mahanarva spectabilis produce a protective foam that supports survival, reduces plant damage, and contributes to adult population establishment. Proteomic profiling combined with protein sequencing and structural modeling revealed foam proteins enriched in functional domains associated with environmental resilience.
