In the western United States, Pandemis pyrusana (Kearfott) (Lepidoptera: Tortricidae), Pandemis limitata (Robinson) (Lepidoptera: Tortricidae), and Choristoneura rosaceana Harris (Lepidoptera: Tortricidae), are the key leafroller
pest species (Madsen & Madsen 1980; Brunner & Beers 1990).
Assessment of three techniques for measuring natural enemy inflicted mortality of leafroller
larvae in commercial orchards.
A leaf-disk bioassay to seven concentrations of pyriproxyfen ranging from 0 to 30 ppm on fifth-instar of obliquebanded leafroller
, Choristoneura rosaceana .
caterpillars, in early development, scrape the leaf parenchyma, making a net in the leaflets, which dry out.
Effects of intercropping sesame, Sesamum indicum and false sesame, Ceratotheca sesamoides on infestation by the sesame leafroller
, Antigastra catalaunalis, the green semilooper, Chrysodeixis acuta and the parasitiod, Apanteles syleptae.
In addition, growing management intensification has fostered other secondary disorders such as the apple leafroller
(Bonagota cranaodes), the apple scale (Quadraspidiotus perniciosus), the oriental fruit moth (Grapholita molesta), the 'Gala' leaf spot (Colletotrichum spp.
Besides the big three, some of the other moths that feed on the fruit of apple trees are the lesser appleworm, redbanded leafroller
, green fruitworm, fruittree leafroller
, obliquebanded leafroller
and the oriental fruit moth.
Potential for conservation biological control of the oblique banded leafroller
(OBLR) Choristoneura rosaceana (Harris) in orchard systems managed with reduced-risk insecticides.
reported that Profenofos was found effective in combination with Cypermethrin for controlling the leafroller
, Sylepta derogata and fruit borer, Earias spp infesting the okra crop .
The Bonagota salubricola (Meyrick, 1931) (Lepidoptera: Tortricidae) leafroller
, also known by a synonym, Bonagota cranaodes (Meyrick, 1937) (Brown and Razowski, 2003), is a primary pest in commercial apple orchards in South America.
The recent discovery of light brown apple moth, a leafroller
, in California may affect the management of fruit crops, and because it is a quarantine pest in some markets, the discovery has already had implications for domestic and export trade in produce and nursery stock.
Spiders (Araneae) as potential predators of leafroller
larvae and egg masses (Lepidoptera:Tortricidae) in Central Washington apple and pear orchards.
