Food utilization Efficiency in fifth instar larvae of Antheraea mylitta (Lepidoptera: Saturniidae) infected with Nosema sp. and its effect on reproductive potential and silk production
Journal of Invertebrate Pathology, 2003Co-Authors: S.s. Rath, B.c. Prasad, B.r.r.p. SinhaAbstract:Antheraea mylitta, a sericigenous insect of economical importance is often infected with an intracellular parasite of the genus Nosema. This pathogen is known to cause fatal pebrine disease and is considered as an important factor that strongly influences the development of the host. Larvae developed from the eggs laid by a female infected with Nosema sp. showed extended development period. The increment in the larval weight declined significantly in infected larvae in comparison to uninfected ones. Food consumption, digestion, relative consumption rate (RCR), Efficiency of Conversion of ingested food (ECI), Efficiency of Conversion of digested food (ECD), and relative growth rate (RGR) values declined significantly, but at the same time a significant increase in approximate digestibility (AD) was also observed. Silk production declined in infected larvae. Silk gland weight and shell weight also significantly declined following infection over uninfected larvae. The reproductive potential in adults declined significantly (P

The reproductive potential in adults declined significantly (P<0.001) with decrease in ovary weight (31.6%), fecundity (54.1%), and fertility (34.9%). Egg chorionation was also affected in adults, which developed from infected larvae. The maternal infection level in one generation (10.4 x 10(6) spores/female) decreased significantly in the next generation (8.0 x 10(6) spores/female).

Responses of Helicoverpa armigera to Tomato Plants Previously Infected by ToMV or Damaged by H. armigera
Journal of Chemical Ecology, 2008Co-Authors: Tse-chi Shen, Yi-hua Chen, Shaw-yhi HwangAbstract:We report the comparative inducing effects of a phytopathogen and a herbivorous arthropod on the performance of an herbivore. Tomato, Lycopersicon esculentum Mill., was used as the test plant, and tomato mosaic virus (ToMV) and corn earworm, Helicoverpa armigera Hübner, were used as the phytopathogen and herbivore, respectively. There were decreases in the Efficiency of Conversion of ingested food and Efficiency of Conversion of digested food when H. armigera was reared on tomato plants that had been previously inoculated with ToMV. However, virus inoculation did not affect feeding or oviposition preferences by H. armigera . In contrast, approximate digestibility, total consumption, relative growth rate, and relative consumption rate were lower for fourth-instar H. armigera that fed on plants previously damaged by the same herbivore. Feeding and oviposition were both deterred for H. armigera that fed on previously damaged plants. The duration of development of H. armigera was also prolonged under this treatment. Infection by ToMV and feeding damage by H. armigera increased the host plant’s peroxidase and polyphenol oxidase activity, respectively, suggesting that the performance of H. armigera may be affected by the induced phytochemistry of the host plant. Overall, this study indicated that, in general, insect damage has a stronger effect than ToMV infection on plant chemistry and, subsequently, on the performance of H. armigera .
