In this study, apple pomace and brewery wastewater were used as nutritive agents and as alternative substitutes for the ingredients (soya flour, wheat germ and yeast extract) without affecting the production of the diet. The quantity of agro-industrial waste added during production was based on a regime where the different nutrients were maintained as a constant, such as proteins (3.71 ± 0.09 g...

'Bing' cherries, Prunus avium L., were obtained from an organic orchard and a conventional commercial orchard. The two groups were examined separately in replicated tests infested with each fruit initially infested with a first-instar codling moth, Cydia pomonella (L.). To simulate commercial postharvest holding conditions, the treatments were 0 (control), 1, 2, 4, 7, 10, and 14 d cold storage ...

1. Hyssopus pallidus Askew (Hymenoptera, Eulophidae) is a gregarious ectoparasitoid of the two tortricid moths species Cydia molesta Busck and C. pomonella L. (Lepidoptera, Tortricidae). It paralyses and parasitizes different larval instars of both species inside the apple fruit, which leads to the death of the caterpillar. 2. We assessed the influence of host species characteristics and host f...

Season-long Þeld studies were conducted in Washington apple orchards that compared the following: (1) twice per week releases of partially sterile codling moths, Cydia pomonella (L.), treated with either 100 or 250 Gy, and (2) combinations of mating disruption plus the release of partially sterile (100 Gy) codling moths, to control wild codling moth populations. No signiÞcant differences in the...

Many fruit boring insect pests are difficult to control because of the short time span during which the damaging stage can be targeted before it becomes protected by the host fruit. We investigated the host location behaviour of the codling moth Cydia pomonella (L.) (Lepidoptera: Totricidae) to its apple host ( Malus domestica Mill.) in the laboratory, with a view to the potential for extending...

1 We evaluated the efficacy and mode of action of commercially available femaleequivalent dispensers of pheromone for mating disruption of codling moth Cydia pomonella (L.) (Lepidoptera Tortricidae). 2 Scentry fibres, but not Hercon flakes, were consistently as or more effective than Isomate C Plus dispensers when applied by hand at 50 dispensers per tree. 3 Individual Scentry fibres were sligh...
