| description | The ladybird <i>Cryptolaemus montrouzieri</i> and the green lacewing <i>Chrysoperla carnea</i> have shown potential for use in augmentative biological control of mealybug pests in greenhouse crops. In the context of combining these predators within an integrated pest management system, the risk of negative intraguild interactions between both predators was evaluated in a laboratory setting. Different life stages of either predator were confronted in petri dish arenas containing a <i>Ficus benjamina</i> leaf, and after 24 h the incidence and direction of intraguild predation (IGP) was recorded for each combination. The effect of adding <i>Planococcus citri</i> nymphs or <i>Ephestia kuehniella</i> eggs as extraguild prey on the level of IGP was also studied. IGP was frequently observed between the two predator species and was asymmetrical in favour of <i>C. carnea</i> in most cases. The presence of extraguild prey reduced the number of IGP events between the predators to a similar extent. The relevance of the observed intraguild interactions for the combined use of these predators in protected cultivation is discussed. |
