Intraguild interactions of a generalist predator, Orius albidipennis, with two Bemisia tabaci parasitoids
The influence of intraguild predation between Orius albidipennis Reuter and two parasitoids, Eretmocerus mundus Mercet or Eretmocerus eremicus Rose and Zolnerowich, on the suppression of Bemisia tabaci Gennadius was investigated under laboratory conditions. Through a non-choice test, the 2nd and 3rd...

Summary: | The influence of intraguild predation between
Orius albidipennis
Reuter and two parasitoids,
Eretmocerus mundus
Mercet or
Eretmocerus eremicus
Rose and Zolnerowich, on the suppression of
Bemisia tabaci
Gennadius was investigated under laboratory conditions. Through a non-choice test, the 2nd and 3rd instar nymphs of
B. tabaci
and larval and pupal stages of both parasitoids were offered separately to both 5th instar nymphs and adults of
O. albidipennis
. In the choice test, various combinations of parasitized and unparasitized preys were provided for two stages of
O. albidipennis
, and their preference was recorded. Both predator stages readily preyed upon unparasitized and parasitized nymphs of
B. tabaci
. The most predation of
O. albidipennis
adults occurred on
E. eremicus
larvae, while for the 5th instar nymphs, it was recorded on
E. eremicus
larvae and pupae. The least predation of both stages was recorded on unparasitized nymphs of
B. tabaci
and
E. mundus
pupae. None of the prey combinations showed any obvious preference of adults and the 5th instars of
O. albidipennis
toward parasitized or unparasitized prey. |
