Vio-trap yellow

Description

The Vio-trap Yellow is a product for the control of the Mediterranean fly (Ceratitis capitata). It is compatible with the ER 834/07 for organic farming. The trap works as bait spray attracting and killing the insects.
After extensive experimentation and years of observation we use trophotropism, which through concerted action of the more effective food attractive substances, as well as chromo-tropism we attract the insect to the trap. The surface of the trap is saturated with the active substance deltamethrin. Its entomologic actions are based on the chemical sensors on the insects’ feet, a characteristic that helps in the absorbance of the active substance and leads to their extermination.
The insect will not be exterminated on the trap but a few meters away from it (when it has finally absorbed the active substance of the trap).
The effectiveness of the trap is tested on citrus fruit, stone fruits, pomegranates, fig and apple-like fruit.

Instructions

  • Before you place the trap on the tree puncture the trap with an awl or with the suspension wire to both points marked with an X.
  • The trap must not touch any leaves and branches and must not be exposed to direct sunlight (Mount it inside the crown of the tree and in the middle of its height).
  • Application dosage: One trap per tree with 50 traps maximum per decare. The suspension of the trap must take place after the fructification and before the fruit starts to mature.
  • In the case that from the time of suspension until the period of harvest more than 2.5 months go by, new traps must be reapplied.
  • If you wish to protect individual trees it is recommended that surrounded trees are also protected since they may have the bug and that more than one trap per tree are used.

Potential problems, diagnosis and treatments

  1.  
    The traps that are exposed to the sun lose their insecticidal operation and their green color. These traps are not effective and should be replaced immediately.
  2. The traps that were hanged without being punctured will not work; activate them by puncturing the points indicated.
  3. The result of their action is not as desired when not placed in the correct dosage. Check the number of traps per decare.
  4. Rainfalls during the critical for Fruit flies months that in total exceed the 150 millimeters launder the insecticide (Deltamethrin) from the surface of the trap. Replace the traps.
  5. You can’t see the flies on top of the trap or underneath it? The insect does not stick to the trap but is exterminated a few minutes later away from the trap.
 

The maximum duration of the trap is 2.5 months.
TEMPORAL STABILITY: keep it in its original carton in a cool and dark place away from strong odors. It retains its effectiveness for one year.
PRECAUTIONS: Keep away from food, beverages and animal feeds. Do not eat or smoke while using it and avoid contact with skin and eyes. Wear suitable gloves. In case of insufficient ventilation use the appropriate breathing apparatus.
FIRST AID: If you feel sick, seek medical advice. In case of irritation of the eyes wash immediately with abundant water and consult an eye doctor. In case of irritation of the skin wash with abundant water and soap and ask for doctor’s advice.

Know-how for growers

The Mediterranean fly (Ceratitis Capitata) is one of the most destructive pests of crops. The genre originated from the Sub-Saharan region and was later spread.The spread is due to its strength in low temperatures and to its ability to affect a wide variety of definitive hosts. Although it is considered one of the main enemies of citrus fruit, it also affects peaches, pears, pomegranates and apple-like fruit. In the Mediterranean basin, the Mediterranean fly’s life cycle can be completed by 4-7 generations and can affect up to 100% of stone fruit.
The biology of the insect is inextricably linked with temperature. When temperatures are not favorable for breeding the insect over-winters in the soil like a poupae. In Crete due to the temperatures the insect over-winters as a thriving insect would.At 32°C the insect’s biological cycle lasts for 15 daysAt 12°C the insect’s biological cycle may last for 100 days. Below 9°C the insect’s biological cycle comes to an end. Only one generation of the insect appears in the winter, while during the summer period more generations appear. In Greece large population outbreaks occur in August, in September and in October. In Southern Greece they occur from April to late December.
Attacks occur when populations are sexually active (4 days after hatching). The fruit preferred are those that their bark has begun to change color. The female can blow approximately 10 to 20 eggs in each hole. During its biological cycle it can blow up to 400 eggs. The implementation of the Med fly trap must be done before the color of the fruit changes, the time of suspension depends on the area where the crop is located.Please contact us for any further information and clarifications.
