Laboratory studies on the biology of Choetospila elegans Westwood (Hymenoptera: Pteromalidae), a parasite of stored grain pests

The biology of the ant-like pteromalid parasitoid, Choetospila elegans was carried out on its host, Sitophilus oryzae. The parasitoid completed its life cycle in 16.93 +or- 1.21 days at a constant temperature of 30 +or- 1 degrees C. The parasitoid passed through 3 larval instars, prepupal and pupal stages during its development. The incubation, larval, prepupal and pupal periods lasted 1.5 +or- 0.07, 6.51 +or- 0.58, 0.91 +or- 0.07 and 8.01 +or- 0.45 days, resp.

The oviposition behaviour of the ant-like pteromalid parasitoid, Choetospila elegans [Theocolax elegans], was significantly influenced by variations in the density of its host (Sitophilus oryzae) and by other parasitoids. Parasitization of the hos...

In laboratory studies in Brazil on the parasitism of Sitophilus oryzae by the pteromalid Choetospila elegans, which was found occurring naturally in grain infested by the weevil, 0, 5, 10 or 20 pairs of S. oryzae were reared in maize grains of the...

Host-size preference of the parasitoids, Anisopteromalus calandrae (Howard) and Choetospila elegans (Westwood) on Sitophilus oryzae (L.) were studied. Host-size had significant effects (P < 0.01) on parasitization and it was highly correated. T...

Some of the relationships between the natural parasitism of S. oryzae (L.) by the microhymenopteran C. elegans (Westwood) was studied under laboratory conditions. The trial was established under controlled conditions of temperature, relative humid...
