This paper (only an abstract of which is given) was presented at the Sixteenth Annual Meeting of the Society of Nematologists held at East Lansing, Michigan, from 16 to 19 August 1977. An account is given of studies carried out in Canada on the effect of parasitism by the mermithid nematode Neomesom...

R. culicivorax juveniles were dissected out of Aedes aegypti larvae 7 days after infection and incubated under controlled conditions in isotonic saline containing a 14C-labelled fatty acid (palmitic acid), monoacylglycerol (glycerol monoolein), or triacylglycerol (glycerol tripalmitate) nutrient sou...

Eggs (0-24 h old and 48-72 h old) of Choristoneura fumiferana were treated topically with fenoxycarb dissolved in acetone. Only 25% of treated eggs hatched, compared to 90% of control eggs. Survival of larvae from treated eggs to induction of diapause in the 2nd instar, and of diapausing larvae, was...

The effect of 7 juvenile hormone analogues on the development of larvae of Choristoneura fumiferana was studied in the laboratory at 23 degrees C, LD 16:8 and 65% RH by topical application of the compounds to early 6th-instar larvae. Fenoxycarb showed the highest potential for control, with an LC50 ...

Isocitrate lyase and malate synthetase, key enzymes of the glyoxylate cycle, were present in postparasites of R. culicivorax. Specific activities of enzymes were higher in adult postparasites than in newly emerged juveniles. Isocitrate lyase had a well-defined pH optimum (7.5), whereas malate synthe...

The haemolymph of larvae of Prosimulium mixtum Syme & Davies/P. fuscum Syme & Davies and Simulium venustum Say parasitised by the mermithid nematode Neomesomermis flumenalis was compared with that of unparasitised hosts with respect to protein, amino acid and carbohydrate composition. The me...

Early 6th-instar larvae of Choristoneura fumiferana were topically treated with the juvenile hormone analogue fenoxycarb, and fat bodies were isolated at varying times post-treatment for metabolic studies. Fenoxycarb impaired lipid synthesis by the fat bodies, suppressing both the synthesis of fatty...
