Magnet TML Plug
Trimedlure is a long established attractant for male Medfly. This chemical is not a true pheromone as it is not produced by the insect itself but the male insect's response is typical of a normal pheromone response.
The Magnet TML Plug dispenser system is designed to provide an effective and reliable system for the monitoring of Ceratitus capitata. The monitoring system is composed of a slow release polymer matrix dispenser containing the attractant designed to control the release of the Trimedlure over a 2-3 month period.
Chemical Name: Trimedlure (t Butyl-4(or5)-chloro-2-methyl cyclohexane carboxylate)
This formulation has been developed to provide a more stable and constant release of the attractant over the longest possible time.
The attractant dispensers from AgriSense are supplied in labelled and batch coded vapour proof sachets.
The dispensers are provided either separately or as components of monitoring systems inside system boxes together with the appropriate trap. The dispensers and systems should be kept under good storage conditions at below 15°C. Kept under these conditions the dispensers and systems will retain their activity and attractancy for a minimum of 18 months.
Bulk storage of dispensers for periods of up to 24 months is possible by refrigeration at temperatures of 4°C or below. We do not recommend storing dispensers for more than this time even in a refrigerator.
AgriSense attractant dispensers have a known and declared period of activity after opening of the sachet. After this time the expired attractant dispenser should be renewed. The old dispenser should be completely removed from the area of use and destroyed to prevent interference with the fresh replacement/ recharge dispenser.
Use either the AgriSense Delta trap or the Jackson trap baited with the Magnet TML plug are recommended for use in most countries.
It should be noted that the exact time of insect emergence will vary with location and seasonal variation and the susceptibility of the crop to be monitored. In the more temperate regions the insects predominantly a problems through the spring and summer. In the tropics it may be present all year round
The traps should be placed at head height within the tree canopy and located centrally within the experimental area being monitored with at least 50m between each trap. One trap should be sufficient to monitor up to 3 hectares of a uniform orchard. In the case of irregular areas 1 trap per hectare is recommended. A minimum of 2 traps is recommended regardless of field size.
Lures should be changed every 6 weeks or earlier. The sticky inserts should normally be changed when the lures are changed. In situations where high insect catches or dusty conditions have led to the deterioration of the glue surface the inserts should be changed. It is recommended that at each reading the trapped insects and any other debris be removed and the glue stirred with the plastic spatulas provided.
Catches should be recorded weekly in low populations but more frequently in orchards with high populations. Record the trap catch on a trap record sheet.
