“…Although this pest apparently prefers to lay eggs on soybean (Martin et al 1976), it is known to be associated with at least 32 additional hosts (Hensley et al 1964, Canerday and Arant 1966, Morishita et al 1967, Harding 1976, Janes and Greene 1970, Martin et al 1976. It is believed that populations begin to build early in the growing season on cotton, Gossypium hirsutum L., and later infest neighboring soybean Þelds (Burleigh 1972, Beach andTodd 1986).…”

Soybean looper, Pseudoplusia includens (Walker), oviposition in cotton, Gossypium hirsutum L., and soybean, Glycine max (L.) Merr., of various stages of plant phenological development was evaluated in field cages in 1994, 1995, and 1996. Overall, females preferred to oviposit on soybean over cotton when both crops were compared in vegetative or prebloom stages, when both crops were blooming, and when soybean was blooming or in early pod stage compared with prebloom cotton. Females preferred to deposit eggs on the lower leaf surface in the upper two-thirds of the plant canopy in cotton and soybean. Oviposition in upper and middle canopy levels varied with plant growth stage. Females tended to lay more eggs in the upper canopy compared with the middle canopy in prebloom cotton and vegetative soybean; more eggs were laid in the middle canopy of blooming cotton and reproductive stages of soybean. Females responded to both cotton and soybean volatiles in an olfactometer. There was no significant difference in response to the two sources of volatiles.

“…The cabbage looper, Trichoplusia ni has been known as one of the most injurious and destructive pests of cruciferous crops in Egypt. Approximately 24 plant species belonging to seven plant families were reported as host plants of this species (HARRISON and BRUBAKER 1943;PARENCIA et al 1962;PROSAD 1963;HENSELY et al 1964;SHOREY and HALE 1965;CANERDAY and ARANT 1966;JANES and GREENE 1970;BRITT and SULIVAN 1974).…”

The influence of four cruciferous host plants viz: Cabbage, cauliflower, turnip and radish on rate of development, mortality, weight of immatures, fecundity and number of annual generations of Trichoplusia ni was experimentally investigated. Host plants exerted no effect on the number of annual generations. Cabbage was the most favourable host plant. Larval development was accelerated when fed on cabbage leaves and somewhat retarded on radish. Larval diet also had enormous effect on pupal duration, generation period and adult longevity. Females fed as larvae on cabbage laid the highest number of fertile eggs. Weights of the different stages were the heaviest when their larvae were fed on cabbage or cauliflower leaves. Zusammenfassung Über den Einfluß der Wirtspflanzenart auf die Entwicklung und Genemtionszahl der Kohleule, Trichoplusia ni (Hb.) in Ägypten Es wurde der Einfluß von 4 Wirtspflanzenarten aus der Familie Cruciferae (Weißkohl, Blumenkohl, Rettich und Radieschen) auf Entwicklungsrate, Sterblichkeit, Larven‐ und Puppengewicht, Fekundität sowie Zahl jährlicher Generationen von Trichoplusia ni untersucht. Die Wirtspflanze zeigte keinen Einfluß auf die Generationszahl. Bevorzugte Pflanzenart war der Weißkohl. Die Raupenentwicklung wurde bei Fraß an Weißkohl beschleunigt, bei Fraß an Radieschen etwas verlangsamt. Die Raupennahrung zeigte starke Auswirkungen auf die Puppendauer, Generationsperiode und Falter‐Lebensdauer. Weibliche Falter, hervorgegangen aus Raupen, die an Weißkohl fraßen, legten die höchste Zahl befruchteter Eier ab. Die Gewichte der verschiedenen Stadien waren nach Fraß der Raupen an Weißkohl oder Blumenkohl am höchsten.

“…Indeed, it is not uncommon to observe mixed populations of plusiine moths on the same crop, and Hensley et al (1964) and Canerday and Arant (1966) have reported the occurrence of several plusiine species on the same host plant species. Similarly, Paschke and Hamm (1961) reported the occurrence of several plusiine species in mint (Mentha spp.)…”

Application of Molecular Techniques to Identification of Three Plusiine Species, Autographa nigrisigna, Macdunnoughia confusa, and Thysanoplusia intermixta (Lepidoptera: Noctuidae), Found in Integrated Pest Management Lettuce Fields in Japan

Three plusiine species, Autographa nigrisigna, Macdunnoughia confusa, and Thysanoplusia intermixta (Lepidoptera: Noctuidae), are commonly found together in lettuce, Lactuca sativa L., fields in Japan. Given the marked morphological similarities between these species and the difficulty associated with discriminating between them using only visual cues, we used multiplex polymerase chain reaction (PCR) assay to distinguish between the three target species. Multiplex PCR uses four primers to simultaneously amplify a specific region of the mitochondrial DNA and produce species-specific banding patterns. The stringency of the method was tested using specimens of different sex, location, and developmental stage, and consistent results were obtained for all samples. Indeed, our method has the potential to clarify the species structure of plusiine species in lettuce fields.
