The predation of aphid hunting wasp, Carinostigmus sp. on fennel aphid, Hyadaphis coriandri is reported from India. The solitary wasp was molecularly identified as Carinostigmus costatus (NCBI Accession No. OQ913733.1). The wasp constructed its nest in the pithy stems of Ceasalpinia pulcherrima (peacock flower) provisioning fennel aphid, H. coriandri. There was a decrease in the population of the fennel aphid, H. coriandri with an increase in the nesting activity of the solitary wasp, C. costatus. Our study indicated that the solitary wasp, C. costatus could be easily conserved by providing pithy stems of C. pulcherrima as nesting habitats around the field borders for natural regulation of aphid infesting fennel

Abstract


The predation of aphid hunting wasp, Carinostigmus sp. on fennel aphid, Hyadaphis coriandri is reported from India. The solitary wasp was molecularly identified as Carinostigmus costatus (NCBI Accession No. OQ913733.1). The wasp constructed its nest in the pithy stems of Ceasalpinia pulcherrima (peacock flower) provisioning fennel aphid, H. coriandri. There was a decrease in the population of the fennel aphid, H. coriandri with an increase in the nesting activity of the solitary wasp, C. costatus. Our study indicated that the solitary wasp, C. costatus could be easily conserved by providing pithy stems of C. pulcherrima as nesting habitats around the field borders for natural regulation of aphid infesting fennel
