Helopeltis spp. (Hemiptera: Miridae) are major sucking
pests of cashew (Anacardium occidentale L.) in India. Cydnocoris
gilvus Brum. (Heteroptera: Reduviidae: Harpactorinae) is recorded
as a potential predator of Helopeltis spp. Biology, mating behaviour
and functional response of C. gilvus were studied by rearing in the
laboratory (temperature 26–28 0
C; relative humidity 89–94 %) with
wax moth, Galleria mellonella, larvae. Based on laboratory rearing,
the fecundity was 56.33 eggs in 8.67 batches per female. The average
stadial period was 37.3 days, with a maximum of 11 days for V instar
and a minimum of 4.5 days for III instars. C. gilvus took 45.5 days
to complete a generation. The innate capacity of natural increase
was 0.07 with a gross reproduction of 67.8 females per female. The
adult exhibited a pin and jab mode of predation in a sequence of
actions. The sequential action of mating comprised arousal (1.32 min),
approach (12.30 min), riding over (140.48 min) and copulation (85.40
min). The predator responded to increasing prey density by killing
more prey than at lower prey densities
