| host egg age and supplementary diet influence the parasitism activity of trichogramma zahiri (hymenoptera: trichogrammatidae). | mass production of egg parasitoids mostly depends on the age of the host. generally old eggs are less preferred by egg parasitoids, which can discriminate between eggs of different ages by using chemical cues. this study was designed to determine the preference, development, and arrestment of trichogramma zahiri polaszek (hymenoptera: trichogrammatidae) parasitizing eggs of its native host, the rice hispa, dicladispa armigera (olivier) (coleoptera: chrysomelidae). eggs of different ages, in addi ... | 2016 | 27114606 |
| effects of temperature on the life table parameters of trichogramma zahiri (hymenoptera: trichogrammatidae), an egg parasitoid of dicladispa armigera (chrysomelidae: coleoptera). | the influence of different temperatures on biological parameters of native strains of trichogramma zahiri polaszek (hymenoptera: trichogrammatidae), an egg parasitoid of rice hispa, dicladispa armigera (olivier) (chrysomelidae: coleoptera), was evaluated in the laboratory on its host. the key biological parameters of the parasitoid t. zahiri in relation to temperature were investigated to find out its candidature as a potential biological control agent of rice hispa. the highest number of eggs p ... | 2015 | 26313191 |
| trichogramma zahiri (hymenoptera: trichogrammatidae) an egg parasitoid of the rice hispa dicladispa armigera (coleoptera: chrysomelidae) in bangladesh. | trichogramma zahiri polaszek sp. n. is described from bangladesh. it has been collected at several localities from the major pest of rice dicladispa armigera (olivier) on which it has an important controlling impact. trichogramma zahiri is compared with known trichogramma species from the region, and diagnostic differences are presented. data on developmental period, adult longevity, egg-laying frequency, host egg age preference and seasonal parasitism rate are presented and discussed. other rec ... | 2002 | 17598304 |
