Resumo(s)
Chrysoperla carnea s.l. (Stephens) (Neuroptera:
Chrysopidae) larvae are generalist predators
feeding on many crop pests while adults feed on nonprey
food. The knowledge about the nutritional
suitability of non-prey food for adults in agroecosystems
is crucial to establish conservation biological
control strategies and is poorly known in olive groves,
where C. carnea s.l. larvae prey on different pests. In
this study, the effect of honeydew secreted by two
hemipteran olive tree secondary pests and 11 plant
species on the life-history parameters (survival,
reproduction and development time) of C. carnea s.l.
were analyzed. Insect pest honeydew from the olive
agroecosystem and several plant species, blooming
throughout the year, were found to improve C. carnea
s.l. adult survival. Pollen consumption seems to be
essential for reproduction. These findings are important
for designing and implementing new conservation
biological control approaches.
