Integrated Concept

AbstractIn 1965, strains of the predaceous phytoseiid mite, Typhlodromus occidentalis Nesbitt, had developed resistance to azinphosmethyl, one of the organophosphate insecticides used to control the codling moth, Laspeyresia pomonella (L.). From 1966 to 1968, trials with integrated mite control in growers’ orchards were carried out successfully preserving the predator T. occidentalis. In most cases, an application of oil at the half-inch green bud stage was applied. The integrated concept of orchard mite control was recommended to the British Columbia fruit industry in 1969 and gained wide acceptance. In 1974, a survey of eight of the original integrated control orchards revealed that none of them had been treated with a summer acaricide since 1968. In six orchards, application of oil at the half-inch green bud stage had been used annually but two had not even received the oil spray. In all the orchards there was a good biological balance of a few predators and a few prey.

Fruit Damage

AbstractThe efficacy of diflubenzuron against the codling moth, Laspeyresia pomonella L., was compared with that of azinphos-methyl in two orchards. Two cover sprays were applied to coincide with peak codling moth activity which was monitored daily with pheromone-baited traps. In the Golden Delicious and mixed cultivar orchards, 187 ppm (mg active ingredient/1.) diflubenzuron provided control comparable to that of 187 ppm azinphos-methyl. In the 47 ppm diflubenzuron treatment, more fruit damage occurred particularly in the mixed cultivar orchard. In this orchard, the addition of Tween 20 to the spray mixture reduced fruit damage markedly.Diflubenzuron appeared non-toxic to the phytoseiid Typhlodromus occidentalis Nesbitt and stigmaeid Zetzellia mali Ewing. In addition, cover sprays did not increase populations of European red mite, Panonychus ulmi (Koch) or rust mites, Aculus spp.The efficacy of diflubenzuron against the codling moth and its compatability with integrated mite control suggest that the compound is a promising agent for pest management programs in apple orchards.

AbstractBecause laboratory and field cage experiments had shown that partially sterile (25 krad dose) male codling moths were sexually more competitive than sterile (40 krad) ones, a study was made in a British Columbia orchard in 1970 to determine whether release of 25 krad moths of mixed sexes would suppress this pest more effectively than release of 40 krad moths. Approximately 75,000 moths/ha were released from 24 April to 25 September for each dose level. In the 25 krad moth release plot, the percentage of apple fruits damaged by this pest at harvest was reduced from 0.21 in 1969 to 0.08 in 1970, whereas in the 40 krad plot damage was reduced from 0.04 in 1969 to 0.02 in 1970.Release of 25 krad moths was also compared with insecticide sprays for codling moth suppression in two small areas at Cawston and Olalla, B.C. At Cawston, the percentage of apples damaged at harvest was reduced from 1.0 in 1969, after three sprays of phosalone, to 0.1 in 1970 after release of irradiated insects. In contrast, per cent damage in a nearby apple orchard, sprayed twice with azinphos-methyl in 1969 and 1970, increased from 2.0 in 1969 to 8.1 in 1970. At Olalla, per cent damage was about the same (0.5) in 1969, after three phosalone sprays, as in 1970 (0.6) after release of irradiated insects. In a neighboring apple orchard, sprayed twice with phosalone in 1969 and 1970, per cent damage was about the same (1.0–1.2) each year.

AbstractCodling moth populations in six orchards in the Okanagan and Similkameen valleys of British Columbia were monitored for 2 seasons with traps baited with trans-8, trans-10, dodecadien-1-ol, the sex pheromone of the codling moth, Laspeyresia pomonella (L.). Sprays were applied if traps within the orchard captured two or more moths per trap per week during 2 consecutive weeks. Traps installed in neighboring orchards minimized male moth influx. A 43.1% reduction in the number of required cover sprays for codling moth control was obtained over a 2-year period compared with a standard three spray program. Fruit injured by codling moth in monitored orchards varied, but was less than 1% in all but one orchard.

And Control

The poultry industry is characterized for its constant search for productivity and profitability, which are based on flock health status. Brazilian Commercial laying hens (Gallus gallus domesticus) have been impacted significantly by mite infestations. This review aims to compile the literature on the occurrence, economic losses, biology, epidemiology and control of mite species considered important for the Brazilian laying poultry industry. The national experience was compared with practices of other countries and a scarcity of studies on this subject in Brazil was evident. The poultry industry has prioritized the use of pesticides to control infestations with little regard for the adverse effects. In this context, the integrated control programs using several strategies simultaneously constitute the best alternative to mite control. Integrated control programs involve measures of chemical, physical and biological nature, as well as attention to cultural aspects. However, studies should be performed aiming at the development of new control methods, evaluating the adequacy of practices developed in other countries to the national reality.

Third Instar Larvae

AbstractAll codling moth larvae, Laspeyresia pomonella (L.), in 100,000 infested apples were killed by fumigation with 32 g/m3 methyl bromide for 2 h at about 17 °C followed by 31–35 days of storage at −0.5 °C. The apples were harvested into bins, fumigated, and placed in a standard cold storage room of a grower’s packinghouse as would be done under commercial conditions. Standard cold storage killed all first and second, and some third, instar larvae in nonfumigated fruit. Cursory sampling indicated that fumigation alone, without subsequent cold storage, could kill all stages. The fumigation and storage treatment did not injure Red Delicious, Golden Delicious, Spartan, Jonathan, or Newtown apples.

SummaryThe codling moth, Cydia pomonella L., achieved four successive generations in Egyptian pear orchards in 1974. Indices of infested fruits showed four peaks of infestation; the first at the end of April, the second during the first week of June, the third during the first week of July and the last at the end of July.
