Definitions

  • TITLE "SYNTH ETIC FRU ITPI ERCI NG MOTH ATTRACTANT" FI ELD OF I NVENTI ON TH IS I NVENTION relates to a synthetic fruitpiercing moth attractant.
  • Fru itpiercing moths sometimes referred to as fruitsucking moths, belong to the genus Eudocima, which formerly included the genera Othreis, Rhytia, Khadira and Adris. They cause damage to around 50 different commercial fruit species resulting in substantial losses to growers through spoilt fruit.
  • the adult moth penetrates the skin or rind of fruit with a barbed proboscis and the extensive probing for juice destroys a large area of tissue beneath the surface.
  • Fru itpiercing moths begin entering fruit crops to feed as soon as the first fruits ripen, as reported in Fay and Halfpapp,
  • Eudocima fullonia Eudocima salaminia
  • Eudocima materna Eudocima materna
  • Eudocima fullonia is the most prevalent species throughout these regions. Eudocima materna also occurs in parts of the
  • Orchard lighting systems wh ich employ green-yellow lights (550 - 580 ⁇ m), can suppress moth feeding. Tests in Australia, of such systems, have measured a 60-70% reduction in moth activity for medium to low population levels. Such systems require considerable investment in electrical infrastructure, in part due to the mandatory safety requirements imposed by energy authorities. These lighting systems do not control any additional pests from entering the area. For those regions where fruitpiercing moths are an irregular problem, such a technique is prohibitively expensive.
  • I nsecticidal cover sprays have never been widely employed against fruitpiercing moths, due to their lack of efficacy, problems with chemical residues arising from the lateness of application relative to crop harvest, and potential interference with the ongoing development of I ntegrated Pest Management (I PM), which is now well advanced in some crops.
  • Carbaryl used on citrus crops, is the only insecticide registered for use against fruitpiercing moths in Australia (as reported in QDPI : I NFOPEST Vers.2.5-Pest Management I nformation System, 2000). However, carbaryl has little efficacy against these moths.
  • Baiting based on organic feed ing attractants has long been used as a control method against fruitpiercing moths, but they have not provided sufficient mortality rates for use in commercial crops.
  • a number of reports namely Hargreaves, Bulletin of Entomological Research 1936, 27, 589-605; Baptist, Indian Journal of Entomology, 1944, 6, 1 -13; Yoon and Kim, Korean Journal of Plant Protection, 1977, 1 6, 127-131 ; Dodia et al. , Tamil Agricultural University Research Journal, 1986, 1 1 , 72-73, disclose the use of feeding attractants, which have included brown sugar, fruit (particularly overripe banana), fruit pulp or fruit juice, honey and beer (or other beverages).
  • Plant-derived attractants for adult moths are extensively referred to in the literature. Most relate to species, which are attracted to flowers, such as Gaura spp. , which attract Helicoverpa zea, as reported in Lingren et al. , Southwestern Entomologist, 1998, No. 21 .

  • FIG 3 compares the number of moths observed on baits with the number of moths observed on fruit on baited trees for a) all Eudocima spp. , and b) all Eudocima exclud ing E. materna.
  • E. materna were excluded for statistical purposes because they occur in lower numbers on the east coast of Australia.

After the initial night's exposure, 30% of the standard baits had been attacked by fruitpiercing moths compared to 40% of the waxed baits. On the third night, 5 moths (all E. fullonia) were observed on the waxed baits and none on the standard ones, and one (1 ) E. fullonia was recorded on fruit on baited trees. After 3 nights, 90% of the waxed baits were found to be pierced compared to 50% of the standard baits. EXAMPLE 1 1
  • This experiment is similar to Example 10, except in that 2% glycerine and 2% paraffin oil was incorporated into the agar baits before waxing.
  • the glycerine and paraffin oil are used as extenders in the baits, i.e. they slow the release of the attractant.
  • 20% (of those without glycerine/paraffin) and 30% (of those with glycerine/paraffin) were attacked on night 1 , and 40% of both types had been attacked after night 2.
