کارایی تله های کارتی زرد رنگ چسبناک به منظور کنترل جمعیت مگس مینوز برگ (Liriomyza sativae Blanchard (Diptera: Agromyzidae در خیار گلخانه ای
Various species of serpentine leaf miner are serious pests of vegetable crops, especially on cucumber and tomato, in greenhouse and open fields. Reduction of chemical insecticides’ use in order to minimize pesticide residues on these crops is one of the most important aspects of food safety. Yellow sticky cards have been used successfully for many pests and can be used for leaf miners too. Ther...
متن کاملScaptomyza nigrita Wheeler (Diptera: Drosophilidae), a Leaf Miner of the Native Crucifer, Cardamine cordifolia A. Gray (Bittercress)
The biology of Scaptomyza nigrita on its host plant, a native crucifer (Bittercress) in the Rocky Mountains, is described. Development of each stage in the life history was studied both in the field and in the laboratory. This is the first documentation of a host for S. nigrita. We examined the activity of adult flies in two adjacent habitats, sun and adjacent willow shade. Adult flies were mor...

Abstract Serpentine leaf miner is one of the serious pests of vegetable crops in greenhouse and open fields, especially on cucumber and tomato. Reduction of synthetic insecticides’ use in order to minimize pesticide residues on these crops is an important basis of food safety. Application of bio-insecticides, especially neem products’ oil, is a very important alternative. Investigation on the ...
متن کاملEvidence for ecological speciation via a host shift in the holly leaf miner, Phytomyza glabricola (Diptera: Agromyzidae)
Evolutionary radiations have been well documented in plants and insects, and natural selection may often underly these radiations. If radiations are adaptive, the diversity of species could be due to ecological speciation in these lineages. Agromyzid flies exhibit patterns of repeated host-associated radiations. We investigated whether host-associated population divergence and evidence of diver...
متن کاملHerbivore Effect on Stature, Fruiting, and Leaf Dynamics of a Native Crucifer
The impact of a native, leaf-feeding chrysomelid beetle (Phaedon sp. nr. oviformis) on bittercress (Cardamine cordifolia: Cruciferae), was evaluated in an exclusion experiment. Multivariate statistical analysis showed a significant increase in plant performance in the rotenone exclusion compared to performance in the paired control treatment. Plant response to the reduction of herbivory was a c...
