“…Studies on the mortality of neonate larvae fed on the foliage of interspecific derivatives from the cross A. hypogaea · A. kempff-mercadoi confirmed the earlier observations of Wightman and Ranga Rao (1994), who reported neonate mortality on the leaf surface of ICGV 86031. In the present study, 29% of the larvae survived on A. kempff-mercadoi, while some of them had extended the larval duration, and others did neither pupate normally nor normal adults were observed (table 2).…”

Tobacco armyworm, Spodoptera litura (Fab), a polyphagous insect, is an important pest of groundnut (Arachis hypogaea L). It is one of the insect pests which had developed resistance to insecticides. Currently there are no cultivars of groundnut which express high level of resistance to S. litura. Wild species of groundnut, which show high levels of resistance, have been identified. Arachis kempff-mercadoi is one such wild species, which is reported to be resistant to S. litura, and indicated that in wild species three flavonoids chlorogenic acid, quercetin and rutin are involved in the components of resistance. In the present study, although these flavonoids had an effect on larval mortality, statistical analysis revealed that quercetin had a major effect due to high correlation of quercetin with chlorogenic acid and rutin. Interspecific derivatives were obtained as a result of crossing cultivated groundnut with A. kempff-mercadoi. In vitro studies showed high percentage of neonate larval mortality when fed on the foliage of interspecific derivatives, majority of interspecific derivatives were detrimental to larval development and had considerable effect on its subsequent progeny. Resistant derivatives were found to have high levels of flavonoids and antibiosis mechanism prevented larval growth. Susceptible derivatives and the female parent, A. hypogaea have low levels of flavonoids.

“…White grubs, the larvae of Scarabaeid beetles, are major pests of groundnut (peanut) in many parts of the world (Wightman and Ranga Rao, 1994), feeding on both roots and pods. For root-feeding species, moisture stress and death of attacked plants commonly results , with consequent negative impact on crop yield.…”

Word count: Abstract -169 words, Main text (including references) -4220 words. AbstractThe damage potential of two phytophagous scarab larvae on groundnut (peanut) yield was determined. Holotrichia serrata, a root and pod feeding species from southern India, was studied in microplots while the damage potential of Heteronyx piceus, a pod feeder from Queensland, Australia, was determined by analysis of on-farm chemical-rate trials. H. serrata larva reduced groundnut yield by an average of 7.52 g/ larva. In crops yielding less and more than 1900 kg ha -1 , H. piceus reduced yield by 4.20 g and 1.43 g/ larva, respectively. These damage potential estimates were used to determine provisional economic injury levels (EIL). For H. piceus, the provisional EIL is 1.67 and 4.91 larvae/ row-metre in crops yielding less and more than 1900 kg/ha, respectively. For H. serrata, the provisional EIL is one H. serrata larva in 7.1 m , more widespread use of chlorpyrifos seed dressing of groundnut is likely to produce regional economic benefits.3

“…In India, the crop occupied an area of 5.48 m ha with a production of 5.43 m tons and an average productivity of 900.0 kg/ha in 2009 (GOI, 2011). The crop is attacked by many species of insects which cause damage ranging from incidental feeding to near total plant destruction and yield loss (Wightman, 1994). In India, tobacco caterpillar Spodoptera litura has been reported as an important pest during the rainy season causing heavy yield losses (35-55 %).…”

Abstract. Changes in quality of host plants under elevated CO 2 (eCO 2 ) conditions likely in future can affect the survival, growth and development, and population dynamics of insect herbivores. The present study aimed to examine the effects of eCO 2 on leaf quality of peanut (Arachis hypogaea L.) and consequent effects on growth characteristics of leaf feeding tobacco caterpillar, Spodoptera litura (Fabricius) over four successive generations. The feeding trials were conducted using peanut foliage grown in open top chambers (OTCs) under two eCO 2 (550 ppm and 700 ppm) concentrations and one ambient CO 2 concentration. Significantly lower leaf nitrogen, higher carbon, higher relative proportion of carbon to nitrogen (C: N) and higher polyphenols content were observed in eCO 2 foliage. Larvae fed with eCO 2 foliage exhibited longer larval duration, higher larval weights and increased consumption in all four generations. Increased Approximate Digestibility (AD) (about 9%) and Relative Consumption Rate (RCR) (7%), decreased levels of efficiency of conversion of ingested food (ECI) (13%), efficiency of conversion of digested food (ECD) (19%), and relative growth rate (RGR) (9%) were noticed in larvae fed eCO 2 foliage. Significant and cumulative effect of CO 2 on S.litura was observed over four successive generations.
