“…An exudate, consisting mostly of malic acid, on the leaflets of chickpea may have influenced M. demolitor host searching behaviour. The detrimental effect of chickpea leaflet exudate on parasitoid performance has been reported previously (Greathead & Girling, 1982 ;Jalali et al, 1988). Highest levels of parasitism were recorded on cotton and soybean.…”

“…More recently, releases have been made in eastern Australian cropping regions (Murray et al, 1992). If these parasitoids have host plant responses similar to those of M. demolitor (Jalali et al, 1988), then establishment releases should not be made into chickpea as such releases are unlikely to be successful. The interactions between the exotic parasitoids and H. armigera larvae on various crop hosts warranted investigation and were the subject of concurrent investigations (Murray et al, in press).…”

Microplitis demolitorWilkinson is an important larval parasitoid of Helicoverpa armigera (Hiibner) and H. punctigera (Wallengren) in Australia. The effect of host plant on parasitism of second instar H. armigera by M. demolitor was investigated in a glasshouse experiment. Parasitism was low (0 %) on chickpea. Moderate to high levels of parasitism (22.4 % to 75.4 %) were recorded on sorghum, sunflower, maize, cotton and soybean. The results suggest that releases of larval parasitoids into chickpea are unlikely to enhance parasitismlevels during the first spring generation of Helicoverpa spp. KEY-WORDS : Host plant effect, larval parasitoids, biocontrol.Microplitis demolitor Wilkinson is a native larval parasitoid of two important crop pests, Helicoverpa armigera (Htibner) and H. punctigera (Wallengren), in Australia. It has been reported from a range of different host plants of Helicoverpa spp. where it sometimes achieves high levels of parasitism (Shepard et aL, 1983 ;Broadley, 1984 ;Zalucki et al., '1986).During favourable seasons, large populations of Helicoverpa spp. develop during winter in inland non-cropping regions and subsequently migrate to eastern cropping regions (Gregg et al., in press). Chickpea have become an important alternative to winter cereals in eastern Australian cropping regions since the mid 1980s, and in southern Queensland, chickpea flowering in spring (September-November) can be an important host for the first spring generation of Helicoverpa spp. Thus chickpea may allow early season population increases which could subsequently threaten traditional summer crops such as cotton, sorghum, soybean, maize and sunflower. In springtime surveys of field crops on the Darling Downs, Queensland, during 1985-87, parasitism of third and fourth instar Helicoverpa spp. by M. demolitor on chickpea was relatively low (0-4.4 %) (I. J. Titmarsh, Unpublished). It was not known whether low parasitism levels were the result of poor performance by the parasitoid on chickpea, as was reported for Cotesia kazak Telenga (Jalali et al., 1988), or simply low seasonal activity immediately following winter. A glasshouse trial was carried out to study the effect of host plant on the level of parasitism of H. armigera larvae by M. demolitor. The implications of these results for Helicoverpa spp. management in southern Queensland are discussed.

“…The importance of both biotic and abiotic factors on the seasonal abundance of H. armigera is poorly understood. Low activity of parasitoids has been reported from chickpea because of dense layer of trichomes and their acidic exudates (Jalali et al, 1988;Murray and Rynne, 1994;Romeis et al, 1999). The ichneumonid, Campoletis chlorideae (Uchida), is probably the most important larval parasitoid on H. armigera in chickpea in India.…”

Insect Pest Problems in Chickpea Chickpea (C. arietinum L.) is the third most important legume crop in the world, after dry beans and peas (FAO, 2003). It is cultivated in 42 countries in South Asia, North and Central America, the Mediterranean region, West Asia and North and East Africa. In recent years, it has become an important crop in Australia, Canada and the USA. Nearly 60 insect species are known to feed on chickpea (Reed et al., 1987) (Table 25.1). The important insect pests damaging chickpea in different regions are: • Wireworms: false wireworm-Gonocephalum spp.; • Cutworm: black cutworm-A. ipsilon (Hfn.) and turnip moth-A. segetum Schiff.; • Termite: Microtermes obesi (Holm.) and Odontotermes sp.; • Leaf-feeding caterpillars: cabbage looper-Trichoplusia ni (Hub.), leaf caterpillarS. exigua (Hub.

“…The most efficient species is the parasitic wasp Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae), for which parasitism levels of up to 30% of young larvae have been reported (Romeis and Shanower, 1996). The low activity of natural enemies in chickpea is most probably due to the dense trichome layer on the plant surface and the acid exudates (Jalali et al, 1988;Murray and Rynne, 1994;Romeis et al, 1999).…”

Chickpea, Cicer arietinum, is the third most important grain legume crop in the world, with India being the largest producer. Insect pests are a major constraint to chickpea production. In India, the legume pod borer Helicoverpa armigera is the major insect pest of chickpeas. However, sap-sucking insects that act as vectors for viral diseases and bruchid beetles in storage are also considered important pests. Here we give an overview over the different management options to control these pests. There is a growing interest in the genetic modification of crops to enhance their resistance against insect pests. Here we present the state-of-theart of chickpea transformation and give an overview on the available insecticidal genes that could be deployed to increase insect resistance in chickpea. Prior to commercialization, transgenic crops have to be assessed for their effects on the environment including the possible impact on non-target arthropods, many of which are important for biological pest control. Therefore, the arthropod-food web in the Indian chickpea system is described. Possible routes through which entomophagous insects could be exposed to insecticidal proteins expressed by genetically modified chickpeas are discussed, and species that could be selected for prerelease risk assessment are recommended.
