Pigeonpea genotypes influence parasitization preference and survival and development of the Helicoverpa armigera larval parasitoid, Campoletis chlorideae
Studies were undertaken to identify pigeonpea, Cajanus cajan (L.) Millspaugh and the wild relative of pigeonpea, Cajanus scarabaeoides (L.) (accession ICPW 125,) genotypes that are hospitable to the pod borer, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) larval parasitoid, Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae) for the management of this pest in pigeonpea based crop...
متن کاملProtease Inhibitors in Wild Relatives of Pigeonpea against the Cotton Bollworm/Legume Pod Borer, Helicoverpa armigera
Cotton bollworm/legume pod borer, Helicoverpa armigera is one of the most damaging pests worldwide. Because of the difficulties associated with chemical control of this pest, emphasis has been placed on developing transgenic plants with resistance to H. armigera. Since toxin genes from the bacterium, Bacillus thuringiensis (Bt) have been deployed on a large scale, there is need to scout for alt...
متن کاملIntegrated Weed Management in Pigeonpea [Cajanus cajan (L.) Millsp.]
Uncontrolled weeds cause considerable losses in the grain yield of pigeonpea. Field experiments were conducted for seven years from 1998 to 2004 on a loamy sand soil to study the effect of weed management on weeds, growth and grain yield of pigeonpea. In some years, weed dry matter was higher than in others, due to variation in rainfall received. Two hand weedings, pendimethalin in integration ...
متن کاملgenetic engineering for increasing resistance of chickpea (cicer arietinum l.) to pod borer (helicoverpa armigera)
pod borer is one of the main factors for yield decrease of chickpea. therefore, breeding of chickpea for resistance to this pest is important. modified cry1ac gene of bacillus thuringiensis in pcry1ac-nptii plasmid containing twin t-dna for cry1ac and nptii genes have been used for transformation of chickpea. at last 38 plants had nptii gene that 36 plants of them had cry1ac gene and two plants...
متن کاملNew Hypervariable SSR Markers for Diversity Analysis, Hybrid Purity Testing and Trait Mapping in Pigeonpea [Cajanus cajan (L.) Millspaugh]
Draft genome sequence in pigeonpea offers unprecedented opportunities for genomics assisted crop improvement via enabling access to genome-wide genetic markers. In the present study, 421 hypervariable simple sequence repeat (SSR) markers from the pigeonpea genome were screened on a panel of eight pigeonpea genotypes yielding marker validation and polymorphism percentages of 95.24 and 54.11%, re...
