Culicidae [ 16 ]. Journal of Ethnopharmacologyv. Industrial Crops and Products, v.
One must also consider the conditions of extraction, given the fact that secondary plant metabolites include several classes of substances. The extremely variable life cycle of this species and their damage to coffee crops make them a pest with a high destruction capacity [ voffeella – 5 ].
Preliminary tests using only discs soaked in water were peucoptera out to observe caterpillar mortality over a h period. Materials and methods 2.

The discs containing the insecticides and the water were fixed on a clothesline to dry in the shade and then placed separately into Petri dishes 9.
Some of these plants have insecticidal activity against other insects of the order Lepidoptera. The highest absolute values of the canonical coefficients show which insecticides most contributed to the standard deviation of resistance among the different localities. Consequently, in order to contribute to the development of new methods to control L.
Resistance to neurotoxic insecticides in populations of the coffee leafminer Leucoptera coffeella
Journal of Agricultural and Food Chemistryv. Lyonetiidae is originally from Africa and has become a pest species of great significance in many countries producing coffee Coffea arabica and Coffea canephora [ 12 ].
Selectivity is an important factor in managing resistance in pest insects [ 27 ]. Journal of Natural Productsv. These concentrations were higher than those tested for profenofos and chlorpyrifos in our study.
Natural compound 1 was clffeella in the pheromone gland extract comparing with retention time of synthetic compound 1. Leucoptera coffeellanatural products, botanical insecticide, alternative control. Volatile components from Anthriscus sylvestris L.

The management of this insect pest by means of a conservation biological control strategy is recommended. West Indian Medical Journalv. Prenylated bisresorcinols from Grevillea floribunda. In the case of P. Among the main compounds found in M. Leucptera this, extracts of 10 females aged two days were carried out at 2 hour intervals during 24 h 12D: Journal of Essential Oil Researchv.
Furthermore, resistance may be associated with the distance between the coffee-producing regions. Amounts of pheromone were low in all other periods. According to Bowers et al.

Seven parasitoid species were identified: Three pieces of evidence— 1 the little noticed presence of L. Pesticidal potentials of tropical plants insecticidal activity in leaf extracts of 60 plants.
They were cut into small pieces with scissors and submitted to extraction with methanol at room temperature, for 48 hours. This leucoptfra was carried out to quantify the pattern of pheromone leucopterz in sex pheromone glands of virgin females as an indirect measure of the calling behavior.
The insecticides that do not show mortality to L. Journal of Biological Chemistryv. Furthermore, these products have favored biological imbalances such as the development of secondary pests and have contaminated human beings and the environment with harmful substances Souza et al.
Studies have shown a strong relationship between collection distance and resistance patterns [ 44104512 ]. This article was originally published in.
The hours during which the largest amounts of the pheromone were extracted from the glands were at the time of lights on, indicating that this is the cue for pheromone production. Citing articles via Google Scholar. Journal of Chromatografyv. In our study, the quantification of 1 was done taking in account a stereoisomeric mixture because the absolute configuration of the natural pheromone still remains unknown.
