“…In Chalcidoidea the notal membrane has a modified, transversely striate band near to the ovipositor base called the laminated bridge (Fig. 3;Fulton, 1933;Copland and King, 1971). In the majority of Hymenoptera the two halves become totally fused medially a short way from the base of the ovipositor and remain so to the However, in some Hymenoptera the situation is more complex.…”

“…3). In all these cases the septum or division always ends shortly before the apex of the ovipositor (Figs 68, 70, 124-127;Fulton, 1933;Bender, 1943;King, 1962;Rogers, 1972). However, in most Symphyta (at least Xyelidae, Tenthredinidae, Pergidae, Cimbicidae, Blasticotornidae, Siricidae, Xiphydriidae and Cephidae) the situation is reversed in that the upper valve has no septum in its middle region, but becomes completely divided into its two constituent parts at the apex (Fig.…”

Chalcidoidea Some previous studies have illustrated transverse sections through the ovipositors of chalcidoids (James, 1926;Fulton, 1933;Lyngnes, 1960;King, 1962;Delanoue and Arambourg, 1965;King and Copland, 1969).

The morphology, function and phylogenetic significance of the hymenopterous ovipositor, as revealed by transverse sections, is explored. Ovipositors (including stings) of > 240 species belonging to some 69 families (representing all superfamilies) have been prepared and examined, and almost 180 are illustrated. Particular attention is paid to Ichneumonoidea. Sections show many new, phylogenetically informative characters as well as providing further insight into ovipositor function. Examples of synapomorphies are given which suggest various groupings at the family or subfamily levels. Functional interpretations are given for several characters, with particular reference to substrate penetration, passage of the egg along the ovipositor and stinging.

“…Little information is available on the developmental biology of P. cerealellae (although see Noble 1932;Fulton 1933). Developmental biology studies including morphological characterization of the preimaginal life stages can be important for the identification of an insect to the species level before adult emergence, which can simplify the quantification of the impact of natural enemies in biological control programs (Bellows and Van Driesche 1999).…”

Pteromalus cerealellae (Ashmead) (Hymenoptera: Pteromalidae) is an ectoparasitoid of several stored-product insect pests. Very little information has been published on its biology and development in host larvae, which typically are concealed within seeds. We documented the development of P. cerealellae within fourth instar larvae of its concealed host, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) infesting cowpea seeds. The preimaginal life stages of the parasitoid were characterized for the first time using morphological structures revealed by microscopic techniques including scanning electron microscopy. Pteromalus cerealellae produces hymenopteriform eggs and larvae. Eggs hatch into 13-segmented first instar larvae with peripneustic condition of spiracles. The larvae have simple, tusk-like mandibles, whereas the mandibles of the pupae and the adults are of the conventional toothed types. Using statistical analyses of the sizes of the larval mandibles and head capsules in conjunction with reliable characters such as the number of exuviae on the body of parasitoid larvae, cuticular folding, and excretion of the meconium, we recorded four larval instars for P. cerealellae. The data showed significant positive correlations between larval mandible lengths and widths of larval head capsules, as well as between mandible lengths and larval instars, suggesting that mandible length is a good predictor of the number of instars in P. cerealellae. Developmental time from egg to adult emergence was *12 d for females and *11 days for males at 30 ± 1°C, 70 ± 5% r.h. and 12L:12D photoperiod.

“…Such sense organs especially chemosensory "pores" are seen in several species of chalcids such as Eurytoma tibialis Boheman (Eurytornidae), Brachymeria lasus Walker (Chalcididae), Tetrastichus rapo (Walker) (Eulophidae), N asonia citripennis (Walker) (Pteromalidae), M icroterysflavus (Howard) (Encyrtidae), Aphytis sp. (Aphelinidae) and in several other species of chalcids (Fulton .1933;Varley 1941;King 1971a, b, 1972a, b, c;Fisher 1971;King and Rafai 1970;Jackson 1966Jackson , 1969Edwards 1954;Wylie 1958;King and Fordy 1970;Bartlett and Lagace 1961;Quendnau and Hubsch 1964;Weseloh 1969;Narendran 1975;Askew 1971). It is suggested by Fisher (1971) that biochemical changes of the host's haemolymph are likely to act as sign stimuli for discrimination between parasitised and unparasitised hosts.…”

Superparasitism is frequently met with in chalcids. The actual mechanism of suppression of the supernumerary individuals is by mutual combat though exceptions to this general rule may also be seen rarely. Many chalcids are known to discriminate between parasitised and healthy hosts. It is an interesting phenomenon that superparasitism occurs even when a female is capable of discriminating parasitised and unparasitised hosts. Several factors play prominent roles in causing superparasitism and the avoidance of superparasitism by a chalcid is the result of maximisation of its reproductive success.
