Acute stress responses include release of defensive volatiles from herbivore-attacked plants. Here we used two closely related monocot species, rice as a representative C3 plant, and sorghum C4 compared their basal stress-induced headspace volatile organic compounds (VOCs). Although both plants emitted similar types constitutive induced VOCs, in agreement with the close phylogenetic relationship several mono- sesquiterpenes have been significantly less abundant relative to rice. Furthermore, spite generally lower VOC levels, some compounds, such green leaf (Z)-3-hexenyl acetate homoterpene DMNT, remained relatively high headspace, suggesting that separate mechanism for dispersal these may evolved this plant. Finally, variable amount VOCs among three cultivars different geographical origins suggested could be valuable resource increase resistance against herbivores.

Host plant resistance is the most researched method for management of planthoppers and leafhoppers in tropical rice. For optimal effects, should be resilient to fertilizer inputs work synergy with natural enemies. In field plot experiments, we examined how rice affect mortality planthopper leafhopper eggs by hymenopteran parasitoids. We used IR62 as a variety Nilaparvata lugens (Stål) [BPH], Sogatella furcifera (Horváth) [WBPH] Nephotettix virescens (Distant) [GLH], IR64 susceptible control. The herbivores were more abundant during wet season sampling low-nitrogen plots. During this study, parasitoids killed between 31 38% BPH 24 52% WBPH four days exposure.

Baryscapus dioryctriae is a pupal endoparasitoid of many Pyralidae pests and has been used as biocontrol agent against insect that heavily damage the cone seed Korean pine. The olfactory system wasps plays an essential role in sensing chemical signals during their foraging, mating, host location, etc., chemosensory genes are involved detecting transducing these signals. Many have identified from antennae Hymenoptera; however, there few reports on Eulophidae wasps. In this study, transcriptome databases based ten different tissues B. were first constructed, 274 putative genes, consisting 27 OBPs, 9 CSPs, 3 NPC2s, 155 ORs, 49 GRs, 23 IRs 8 SNMPs transcriptomes manual annotation.

The behavioral responses of Hypera rumicis L. adults to varying blends synthetic plant volatiles (SPVs) at various concentrations in lieu single compounds are reported for the first time. For this study, Rumex confertus plants were treated with two SPVs different quantities that act as either attractants or repellents insects. Blend 1 (B1) consisted five green leaf (GLVs), namely (Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexenol, (E)-2-hexenol, and (Z)-3-hexen-1-yl acetate. 2 (B2) contained six volatiles, (Z)-ocimene, linalool, benzyl acetate, methyl salicylate, β-caryophyllene, (E)-β-farnesene.

The fall armyworm (FAW), Spodoptera frugiperda, is a major polyphagous pest that mainly feeds on maize and other cash crops. Understanding S. frugiperda’s behavior different host plants facilitates the development of effective integrated management (IPM) plans. Therefore, this study investigated oviposition preferences frugiperda females among using no-choice, two-choice, multiple-choice bioassays. In no-choice bioassays, para grass, Urochloa mutica (Forssk.) (Poales: Poaceae); maize, Zea mays (L.) napier Pennisetum purpureum (Schumach) Poaceae) were identified as highly attractive, while sweet sorghum, Sorghum dochna sunhemp, Crotalaria juncea (Fabales:Fabacea); Egyptian clover, Trifolium alexandrinum desmodium, Desmodium uncinatum (Jacq.) natal melinis repens (Zizka) molasses Melinis minutiflora (P.Beauv.) mung bean, Vigna radiata (R. wilczek) (Fabales: Fabaceae) exhibited reduced effects. Two-choice bioassays revealed levels attractiveness repellency plant combinations. mimicking an intercropping scenario, differences in number eggs egg mass observed for M:S:D:W (maize, cage wall), S:D:M:W (sunhemp, D:M:S:W (desmodium, wall).
