“…The potential value of beneficial insects such as A. bilineata in integrated control programs involving chemical insecticides is limited, in part, by their level of susceptibility to such compounds. Applied at rates necessary to control D. radieum, cyclodienes were also lethal to A. bilineata populations (Morris, 1960;Read, 1960Read, , 1964. Organophosphates and carbamates, to varying degrees, were found to be toxic to A. bilineata (Hassan, 1969;Chapman & Eckenrode, 1973;Kirknel, 1978;Fin-layson et al, 1980).…”

The insect growth regulator Dimilin®, common name: diflubenzuron, applied at concentrations effective against the cabbage maggot Delia radicum L., did not affect the hatching of eggs of the staphylinid predator and parasite, Aleochara bilineata Gyllenhal. Applied externally in distilled water, Dimilin was non‐toxic to first instar larvae, to larval instars developing within host puparia, and to adults. When Dimilin was dissolved in dimethylsulfoxide, then applied to the exoskeleton of host puparia, emergence of A. bilineata adults was suppressed. The conventional insecticide Furadan, at a concentration (0.001% in distilled water) equal to the lowest concentration of Dimilin used, was toxic to both eggs and larvae of A. bilineata. Résumé Effet toxique du diflubenzuron, un régulateur de croissance des insectes, sur le staphylin Aleochara bilineata un parasitoïde et prédateur de la mouche du chou Delia radicum Lorsqu' appliqué dans des concentrations efficaces contre la mouche du chou Delia radicum L. (0.1, 0.01, 0.001% p/v dans de l'eau distillée), le Dimilin (diflubenzuron), un régulateur de croissance des insectes, n'a pas affecté l'éclosion des oeufs de Aleochara bilineata Gyllenhal, un staphylin prédateur et parasite. En application externe, à la plus forte concentration (0.1% p/v dans de l'eau distillée), cet inhibiteur de synthèse de la chitine s'est avéré non toxique pour les larves du premier stade, les stades larvaires qui se développent à l'intérieur du puparium de l'hôte, et les adultes. Le traitement au Dimilin n'a pas affecté la fertilité des staphylins adultes. Cependant, lorsque le diflubenzuron était dissous dans du diméthylsulfoxyde et appliqué sur l'exosquelette du puparium de l'hôte, l'émergence des adultes de A. bilineata était éliminée. L'insecticide conventionnel Furadan (carbofurane), à une concentration égale à la plus faible concentration de Dimilin utilisée (0.001% p/v dans de l'eau distillée), s'est avéré toxique à la fois pour les oeufs et pour les larves de A. bilineata.

Surface damage was rated in increments of10 per cent. Ten per cent signified 1 to 10 per cent of the surface damaged; 100 per cent signified 90 to 100 per cenr of the surface damaged ro such an extent that to remove evidence of damage the whole root would have to be peeled.…”

Three spray treatments of heptachlor at 4 pounds, dieldrin at 4 pounds, or endrin at 2 pounds in 80 gallons of water per acre in a 12-inch band centered on the rutabaga row eliminated maggots of Hylemya floralis (Fall.) about the roots and prevented damage by the maggots, when applied at intervals of 10 or 11 days beginning within 2 or 3 days after the start of oviposition. Residues of dieldrin were below and those of endrin were above the legal tolerances in Canada. Residues of heptachlor (epoxide not determined) were below the legal tolerance. A single soil band treatment of heptachlor, dieldrin or aldrin dust at 5 pounds per acre, applied in a 12-inch band on the seeded rows and incorporated immediately into the top [Formula: see text] to 1 inch of soil, gave similar control, but insecticide residues in the rutabaga were not determined. None of the treatments was phytotoxic.

“…are widely distributed especially in Europe and North America. There is also considerable evidence, which suggests that insecticides applied to soil as a protection against root maggots greatly suppress parasitisation (MORRIS 1960, READ 1960, COAKER 1966, SUNDBY, TAKSDAL 1969and HERTVELDT 1970.…”

A laboratory test to examine the effect of insecticides on the parasite Trybliographa r a p e West. is described. The materials tested were chlorfenvinphos, bromophos, diazinon, dimethoate, parathion-ethyl and lindane, which are commercially used in the Federal Republic of Germany for the control of the cabbage root fly Hylemya brassicae (BouchC).The initial toxicity of bromophos, diazinon and parathion-ethyl was extremely high. When exposed to soil freshly treated with these materials, total mortality occurred in the first few hours of the test. Dimethoate acted slower but also caused total mortality. Chlorfenvinphos and lindane were much less harmful. In test exposures with soil a t different insecticide residue-ages, the toxicity of bromophos and lindane was found to persist for much longer periods of time, com ared with that of parathion-ethyl, diazinon and dimethoate. Among the insecticides t e s t e l bromophos was the most harmful material, killing the largest number of parasites and chlorienvinphos was the least toxic, in which very low percentage mortalities occurred.A field experiment to study the effectiveness of these insecticides in controlling the cabbage root fly and the harm they may cause to the parasites showed that chlorfenvinphos gave the best protection followed by bromophos, diazinon, dimethoate, parathion-ethyl and lindane in order of their diminishing effectiveness. Adult T . rapae emerged in varying numbers from pupae collected from all the insecticide treated plots but the incidence of parasitism was much reduced in the treated plots, compared with the untreated controls.With the support of the foundation ,,Deutsche Forschungsgemeinschaff".
