“…Woolly apple aphid (WAA), Eriosoma lanigerum (Hausemann) (Homoptera: Pemphigidae), is a prevalent pest within Hawke's Bay apple orchards and can cause significant damage to the trees (Bradley et al 1997;Mols & Boers 1999) by sucking sap from new branches and shoots. WAA forms colonies that become covered in waxy filaments, which prevent effective chemical contact (Monteiro et al 2004).…”

The parasitoid Aphelinus mali controls woolly apple aphid (WAA; Eriosoma lanigerum) in New Zealand apple orchards The effects of seven pesticides on A mali exposed to residues on filter paper were assessed in a laboratory bioassay immediately postapplication Spinosad at label rate was moderately to highly toxic but other compounds and lower rates of spinosad had no detrimental effects on A mali Another bioassay incorporating field application and exposure to aged residues on leaves determined the toxicity of carbaryl diazinon indoxacarb and lime sulphur Carbaryl had the greatest residual toxicity to A mali on harvested leaves causing 85 mortality 21 days after application declining to 40 by 28 days In contrast diazinon initially caused high mortality but residues were not toxic 15 days after application while indoxyacarb and lime sulphur were not toxic Minimising the use of pesticides toxic to A mali should benefit the sustainable management of WAA in apple orchards

“…Several natural enemies affect the aerial colonies of woolly aphids and although its relevance varies according to the latitude and orchard management (Lordan et al, 2015), the joint occurrence of predators and parasitoids can mean better control of this pest (Gotinjo et al, 2015). The most frequently mentioned woolly aphid predators are: syrphids, coccinellidae, lacewings, bedbugs and earwigs (Walker, 1985;Asols, 1997;Mols and Boers, 1999;Short and Bergh, Cuadro 2. Abundancia del pulgón lanígero en huertos de manzano con diferente manejo de plagas en Cuauhtémoc, Chihuahua, durante 2010 y 2011.…”

“…In relation to the natural enemies of woolly aphid, coccinellidae species have been recorded: Adalia bipunctata (L.), Coccinella septempunctata L., Coccinella transversoguttata Brown, Harmonia axydiris Pallas, Hippodamia convergens Guérin-Méneville, Hippodamia tredecempunctata (L.); Syphids: Heringia calcarata (Loew), Syrphus opinatur Osten Sacken, Eupeodes fumipennis Thomson, E. americanus Wiedeman, Syritta pipiens (L.), Eumerus stigatus (Fallen), Melangyna umbellatarum (F.); Chrysopods: Chrysopa nigricornis Burmeister, Chrysoperla plorabunda (Fitch), Hemerobius spp. ; dermapterae: Forficula auricularia L. and the parasitoid Aphelinus mali (Haldeman) (Asante, 1997;Mols and Boers, 1999;Nicholas et al, 2005;Mansilla and Pérez, 2006;Berg and Short, 2008;Beers et al, 2010, Moerkens et al, 2012Gontijo et al, 2012;Dicu et al, 2013;Gontijo et al, 2015), with syphids showing the highest relative frequency 62.7%, followed by lacewings 23.6%, Coccinellids 8.9% and other predators including bedbugs, spiders and earwigs with 4.8% (Gontijo et al, 2015).…”

Enemigos naturales asociados al pulgón lanígero en huertos de manzano con diferente manejo de plagas

El pulgón lanígero (Eriosoma lanigerum Hausmann) es un fitófago que incide en huertos de manzano [Malus sylvestris (L.) Mill. var domestica (Borkh) Mansf.] establecidos en el estado de Chihuahua. Para su combate se ha privilegiado el uso de insecticidas convencionales, incurriendo en aplicaciones extemporáneas que posiblemente repercuten en la baja ocurrencia de enemigos naturales. Con base en lo anterior y la reducida información sobre enemigos naturales del pulgón lanígero del manzano en México, durante los años 2011 y 2012 se realizó el presente trabajo con la finalidad de identificar la incidencia de depredadores y parasitoides asociados a colonias de pulgón lanígero en huertos de manzano con diferente manejo de plagas. Por manejo del huerto, se detectaron 38 y 35 ejemplares para los huertos sin manejo y con manejo integrado de plagas, valores que fueron estadísticamente iguales entre sí y diferentes a los 12 ejemplares detectados en el huerto con manejo convencional. Las especies de depredadores asociadas a colonias de pulgón lanígero en Chihuahua fueron: Hippodamia convergens, Chrysopa nigricornis, Chrysopa oculata, Chrysoperla rufilabris, Chrysoperla comanche, Chrysopa spp., Allograpta obliqua, Sirphus sp. y Toxomerus sp., mientras que como parasitoides se detectó solo a Aphelinus mali.

“…The dilemma for growers is that biological control outcomes are unpredictable because they are influenced by seasonal temperatures, which affect emergence and development rates of both the aphid and the parasitoid (Mols & Boers 1999;. Spring temperatures during post-diapause development of A. mali affect emergence timing of the parasitoid (Trimble et al 1990;.…”

“…Woolly apple aphid (WAA), Eriosoma lanigerum (Hausemann) (Homoptera: Pemphigidae), is a serious and increasing threat to the New Zealand apple industry. Growers face issues with susceptible rootstocks used for intensive plantings, a lack of Integrated Fruit Production (IFP)-compatible insecticides and unpredictable biological control outcomes influenced by seasonal temperature variations, which affect emergence and developmental rates of the parasitoid and WAA (Mols & Boers 1999;.…”

A spray strategy to control woolly apple aphid (Eriosoma lanigerum WAA) was assessed on apple orchards in Nelson Carbaryl applied for fruit thinning was either sprayed alone or combined with diazinon on Braeburn apples at four orchard sites infested with WAA The diazinon plus carbaryl treatment reduced WAA levels and there were lower numbers of WAAinfested shoots with considerably fewer colonies on branches and shoots in November Numbers of WAA colonies on shoots in January were 50 lower overall in the diazinon plus carbaryl treatment There was an initial decline in numbers of the WAA parasitoid Aphelinus mali in both treatments but they increased steadily during the season and high levels of parasitism were evident by harvest The parasitoid was able to suppress the lower populations of WAA in the diazinon plus carbaryl treatment and this resulted in significantly lower levels of WAA shoot and fruit infestation and bud damage in late March
