AbstractDacnusa dryas (Nixon), a multivoltine parasite of the alfalfa blotch leafminer, Agromyza frontella (Rondani), has become established in eastern Canada. Adults deposit their eggs singly in the hemocoel of the actively feeding host larvae. A trophamnion forms between the chorion and the embryo and the elliptical egg swells, becoming spherical and transparent. On hatching, the trophamnion adheres to the 1st instar throughout its development. The first moult occurs in the newly formed puparium where development of the parasite is completed. Winter is passed as a mature larva within the soil-borne host. Descriptions of the immature stages are given.

Tachinid Parasite

The tachinid parasite Ceromasia auricaudata Tns., which had been transferred from Western to Eastern Canada for release against the spruce budworm Choristoneura fumiferana (Clem.), is an insect that deposits microtype eggs on leaves which are later ingested by the host. Eggs hatch immediately after ingestion, but the parasite does not develop beyond the first larval stage until the host pupates. Then the larva develops rapidly, maturing within 10 days. The mature larva leaves the host pupal case, drops to the ground, and pupates usually within 24 hr. Nine to 11 days later, the adult emerges. Very little information is available on the overwintering habits. The life history, habits, and rearing methods are outlined and important characters of the immature stages are illustrated and described.

Pass Through

Sap beetle, Epuraea ocularis Fairmaire usually lays eggs and breeds on fermenting overripe fruits, and larvae pass through different instars before pupating on soil. In laboratory condition, mating pairs of adults copulated and females laid eggs in clusters; larva hatched out in 1 to 2 days, passed through four instars; mature larva migrated to soil for pupation. Larval development took about 12 to 17 days; and adult hatched out of pupa in about 4 to 5 days. Detailed morphology of egg, larva and pupa is presented herein, and significance of larva in taxonomy of beetles has been indicated.

The morphology of larva and pupa, as well as larval mines of Elachista zonulae (Sruoga, 1992) are described and illustrated for the first time. Carex firma Host is reported as a new host plant ofthe species; previously only Carex sempervirens Vill. was known to be host plant of E. zonulae. Some information on life history of this elachistid moth is also provided. The mature larva is 4.5—5.5 mm long. Pupation takes place usually at base of leaf blade of the food plant. The species is univoltine and hibernates as young larva.

AbstractCyrtogaster vulgaris Walker, a pupal parasite of the alfalfa blotch leafminer, Agromyza frontella (Rondani), acts as a secondary agent as well. The adults, which deposit their eggs within host puparia, apparently do not discriminate between healthy leafminers and those parasitized by Dacnusa dryas (Nixon). The egg and larval cephalic structures of C. vulgaris are described and illustrated and the final-instar larval skins of the two parasite species are compared.

The first instar and mature larva and pupa of Cassidispa relicta Medvedev, 1957, a newly recorded species from China, are described and figured. The chaetotaxy of the head, mouthparts, legs, and dorsal and ventral surfaces of the body is described. This is the first detailed description of immatures in the genus Cassidispa. Diagnostic characters of this species are compared with other described immatures of some Hispini genera. Biological notes on C. relicta, such as host plants, feeding patterns of adults, structure of larval mines and life history, are also presented.

The first comprehensive information on the bionomics of the digger wasp Oxybelus variegatus Wesmael, 1852 is presented. Females nested in small aggregations in crevices between paving stones of a frequently used pedestrian pathway in lowland agricultural wasteland. Nests were dug in the ground using mandibles, legs and abdomen. The nest consists of a main burrow with one or, rarely, two cells. The mature larva is described for the first time. The egg stage lasts for about two days before the larva hatches. The female provisioned each cell with an average of 11 paralysed male flies of Delia platura (Meigen, 1826) (Diptera: Anthomyiidae). Numerous females of dipteran kleptoparasites were observed in the nesting area of O. variegatus. However, only a few nests were infested by larvae of Senotainia conica (Fallen, 1810).

This publication describes the life history and morphology of the immatures of Spaethiella intricata associated with bromeliads. Immature stages were previously unknown for the species. Adults and larvae are bromeliad leaf scrapers. First and fifth instar larvae and pupa of S. intricata are described and illustrated with further discussion upon the epipharynx of some Cassidinae species belonging to few tribes. General observations of the known Hemisphaerotini immatures and adults are compared.
