Pheromones

Description

• The Cuelure is a synthetic product related with the sexual pheromone produced by dipeptra of the Bactrocera genus , highly effective for the management of various fruit flies. It can be used for monitoring populations programs ( monitoring ) as well as management ( mass capture ).

• Cuelure is chemically related to the sex pheromone produced by female melon flies to attract males for mating. Pheromones are volatile chemicals produced by a given species to change the behavior of other individuals of the same species. Cuelure will be initially used to attract male melon flies to prevent them from mating and producing the next fly generation. The name cuelure is derived from the Latin name of the target melon fly, Bactrocera cucurbitae (Coquilette). Cuelure is a colorless to pale yellow liquid . It volatilizes slowly. Tests show that cuelure attracts male melon flies more effectively than the unmodified sex pheromone.

Fruit Flies Attracted To Cuelure Block

• Bactrocera cucurbitae
• Bactrocera newmanii
• Bactrocera tryoni
• Bactrocera neohumeralis
• Bactrocera frauenfeldi
• Bactrocera nigrotibialis

Usage Sites: Cuelure is expected to be used initially in producing end products that attract and inactivate melon flies on such crops as Cucumber, Gherkin, Melons, Pumpkin, Bitter gourd, Coccinia (Little gourd), Snake gourd, Ridge gourd, Bottle gourd & other Cucurbitaceous crops and some fruits (Mango, Guava, Sapota, Citrus etc).

Description

• Methyl Eugenol is a type of phenylpropanoid element which means the methyl ether of eugenol. It is produced by methylation of eugenol and has alkyl group attached to its benzene ring. Methyl Eugenol is found in various essential oils.
• Its IUPAC name is 1,2-Dimethoxy-4(prop-2-en-1-yl) benzene. Methyl eugenol will be used in insect traps and lure products to attract certain fruit flies such as the Oriental fruit fly on affected food crops. Methyl eugenol (4-allyl-1,2-dimethoxybenzene-carboxylate) and cue-lure [4-(p-acetoxyphenyl)-2-butanone] are highly attractive kairomone lures to oriental fruit fly, Bactrocera dorsalis (Hendel), and melon fly, B. cucurbitae (Coquillett), respectively.

Fruit Flies Attracted To Methyl Eugenol Block:

• Bactrocera dorsalis
• Bactrocera zonata
• Bactrocera correcta
• Bactrocera papayae
• Bactrocera musae
• Bactrocera invadens 

Usage Sites: Methyl Eugenol is expected to be used initially in producing end products that attract and inactivate melon flies on such crops as Mango, Guava, Papaya, Citrus & all fruit crops.
