“…Despite the polyphagous nature of the species as a whole, selection of an appropriate new host plant can impact larval growth and development. Larval performance of individual FAWs from different host strains varies considerably among host plant species (Pashley, 1988; and also can be impacted by previous damage from other herbivores (Bultman and Conard, 1998;Tindall and Stout, 2001). Given that volatiles from herbivoredamaged and undamaged plants differ quantitatively at a minimum, foraging FAW are presented with differences in olfactory cues when making a choice.…”

Attraction of Spodoptera frugiperda Larvae to Volatiles from Herbivore-Damaged Maize Seedlings

Plants respond to insect attack with the induction of volatiles that function as indirect plant defenses through the attraction of natural enemies to the herbivores. Despite the fact that volatiles are induced in response to caterpillar attack, their reciprocal effects on the host location behaviors of the same foraging herbivores are poorly understood. We examined orientation responses of sixth instar fall armyworm [FAW; Spodoptera frugiperda (Smith)] to odors from herbivore-damaged and undamaged maize seedlings (Zea mays var. Golden Queen) in y-tube olfactometer bioassays. While both damaged and undamaged maize seedlings were attractive compared with air, sixth instars preferred odors from damaged maize seedlings over odors from undamaged maize seedlings. Gas chromatography-mass spectrometry analysis of plant volatiles revealed that linalool and 4,8-dimethyl-1,3,7-nonatriene were the major volatiles induced by FAW herbivory 6 hr after initial damage. Given its prominence in induced plants and established attractiveness to adult FAW, linalool was evaluated both as an individual attractant and as a supplemental component of whole plant odors. Volatile linalool was more attractive than air to sixth instar FAW over a broad range of release rates. FAW also responded selectively to different amounts of linalool, preferring the higher amount. The orientation preferences of FAW were readily manipulated through capillary release of linalool into the airstream of whole plant odors. FAW preferred linalool over undamaged plant odors, and linalool-supplemented plant odors over unsupplemented plant odors, indicating that olfactory preferences could be changed by alteration of a single volatile component. These results suggest that although many induced volatiles attract natural enemies of herbivores, these defenses may also inadvertently recruit more larval herbivores to an attacked plant or neighboring conspecifics.

“…For example, in experiments on the rice water weevil (Lissorhoptrus oryzophilus, a root herbivore) and fall armyworm (Spodoptera frugiperda, a foliage-feeding herbivore) on rice, severe damage by one herbivore decreases densities and growth rates of the other herbivore by up to 40%. 110 In some cases, VOCs from damaged plants actually increase herbivore recruitment. This specific herbivore behaviour could help to find mates 111 or host plants in environments where preferred hosts are sparse (since a bad host is better than no host at all).…”

“…Interactions between RWW and other insects in rice have been studied in the US (Way et al, 1983;Tindall and Stout, 2001). In California, RWW damage can reduce competing ability of rice plants towards weeds Monochoria vaginalis Presl and Sagittaria montevidensis Cham.…”

“…Smith) (Lepidoptera: Noctuidae), severe defoliation by the armyworm can decrease RWW densities by 32% and reduce larval weight by 48%. Meanwhile, RWW damage can reduce growth rate of the armyworm by 9%~37% (Tindall and Stout, 2001 However, in Asia where RWW has occurred as an invasive species, little is known about interactions between RWW and indigenous insects. The striped stem borer, Chilo suppressalis (Walker) (Lepidoptera: Pyralidae) is one of the most serious pests of rice in temperate and subtropical Asia.…”

Abstract:The rice water weevil (RWW) Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) is an invasive insect pest of rice Oryza sativa L. in China. Little is known about the interactions of this weevil with indigenous herbivores. In the present study, adult feeding and population density of the weevil, injury level of striped stem borer Chilo suppressalis (Walker) (Lepidoptera: Pyralidae) and pink stem borer Sesamia inferens (Walker) (Lepidoptera: Noctuidae) to rice, as well as growth status of their host plants were surveyed in a rice field located in Southeastern Zhejiang, China, in 2004 with the objective to discover interspecific interactions on the rice. At tillering stage, both adult feeding of the weevil and injury of the stem borers tended to occur on larger tillers (bearing 5 leaves) compared with small tillers (bearing 2~4 leaves), but the insects showed no evident competition with each other. At booting stage, the stem borers caused more withering/dead hearts and the weevil reached a higher density on the plants which had more productive tillers and larger root system; the number of weevils per tiller correlated negatively with the percentage of withering/dead hearts of plants in a hill. These observations indicate that interspecific interactions exist between the rice water weevil and the rice stem borers with negative relations occurring at booting or earlier developmental stages of rice.
