Laboratory evaluation of different host plants and Taxodium distichum ethanolic extract on Nezara viridula (Hemiptera : Pentatomidae)‎

Abstract EN

The different host plants and ethanolic extract of Taxodium distichum were evaluated on mortality and some biological parameters of green sting bug Nezara viridula (L.) (Hemiptera: Pentatomidae) a major pest of some economic crops.

The data revealed that the adult survival on okra pod, cabbage and lettuce were 52.94, 30 and 27.27% with longevity 9.56, 7.66 and 6.8 days, respectively.

In addition, the insecticidal activity of ethanolic extract of T.

distichum, it had a more potent on controlling N.

viridula where LC50 and LC90 were 7.49 and 14.41% after 72h post-treatment.

The ethanolic extract induced noted a decline in the longevity of male (4.42, 3.14) and female (5.57, 2.71) at 5% and 10% conc., respectively in comparison to control 14.71 and 22.57 day for male and female.
