Trap re-usability : can be used upto 3 seasons. Identification of potential biological control agents will conducted in the laboratory. No parasitism was observed in 1st instar. E. diaspidicola is apparently highly host specific, attacking only a few species of diaspidid scales. A new thrips species (Thrips parvispinsus (Karny), Thysanoptera) has been discovered on papaya on Hawaii. Two species of predatory beetles were observed attacking adult female and immature scales. Significant Activities that Support Special Target Populations Population genetics of aphids from papaya orchards to understand epidemiology and develop sustainable management tactics of Papaya ring spot virus, DNA sampling of the green peach aphid, Myzus persicae and the melon aphid, Aphis gossypii, across the major Haw�n Islands. Protecting Your Fruit Wash fruit as soon as you bring it home. Fruit flies will get stuck on the tape and can’t escape. Approach (from AD-416) Using unique gene constructs, screen transformants for resistance to Papaya Ringspot Virus and delayed fruit softening. Soapy water in the bottom of the pots means that once the flies have been lured in, they fall into the water and drown. Papaya fruit was left to ripen at room temperature (22oC) and fruit were checked daily to observed disease development. Punch holes in the top of the jar. If you opt for the protein-based bait pots, they need to be every two metres apart. Action: Use paper or fine mesh cloth bags to prevent maturing fruit being stung. This project analyzes the biology, pattern of invasion, genotypic diversification and the genotypes of Aphis gossypii and Myzus persicae that colonize papaya plantings and their alternative host plants across the five major Hawaiian Islands. Primers were designed to flank the upstream regions and used in PCR on the genomic DNA extracted from SunUp (CTAB method). We are continuing to select a line that has stripped fruit. Here are few things you can do to prevent a fruit fly invasion in your home: Slow down the ripening of fruit and vegetables by keeping them refrigerated Fruit stored on countertops should be washed well and covered Empty kitchen trash cans often, especially if they contain food items Here’s What to Do!

The cold is more tempered in this area due to several large lakes nearby, so I’m not worried about the plants freezing, but I am a little worried about the wasps now. Replace the bags every 10 to 14 days during fruit development. Our microsatellite marker study showed population differentiation within A. gossypii and Myzus persicae. Fruit flies cannot develop in certain fruits such as papaya, banana and sapodilla when they are green. Since there are no native diaspidid scales in Hawaii, the outlook for gaining permission to release E. dispidicola against white peach scale is positive. However, they're in for a surprise—since the dish soap breaks the surface tension of the vinegar, the fruit flies fall in and drown. A female papaya fruit fly produces about 100 eggs and lays around 10 at a time in each papaya fruit it visits. Parasitism rates by Anagyrus loecki ranged from 3.3 to 20 % in adult females whereas parasitism on 2nd and 3rd instars was lower than 5%. Growth data were collected; however, yield data were obtained only from Laie but not from Kahuku due to the flood in early 2006. The amplified PCR products were separated by electrophoresis, purified, and their DNA sequence was determined to confirm the gene identity and ensure there were no nucleotide errors. This will remove any possibility for fruit flies to breed in these fallen fruits. In the southern part of the state and warmer regions along the coast, the papaya fruit fly is a serious pest. Fruit flies find the fruits to lay in by their colour, shape and the smell of the fruit, leaves and the bacteria on them. A … neem cake and 1 Kg.

Among the natural enemies agents present, Cybocephalus nipponicus is the easiest to observe in the field due to it�s relatively larger size and apparent higher density. The fly has become established in southern Florida, and has spread to wherever this plant is grown. Anthracnose usually developed after 1 week at (22oC) and stem end rot developed at a slower rate after 10 days. How many to use : 6 Traps / acre or 15 traps / hectare. which has been considered to be playing a major role in suppressing papaya mealybug on Maui infestations was brought to Oahu by the Hawai'i Department of Agriculture. We proceeded to attempt mass-rearing the parasitoid to complement the HDoA redistribution efforts. Importing goods. This line could be used to separate the fruit in the market. In both fields, about 90% of all trees are infested with female scales and about a quarter of all trees had high levels of female scale infestation. Results show that infestation in these fields are high and that reproductive, indicated by the presence of males, crawlers, and young scales is almost Additional details of research can be found in the report for the associated in- house CRIS 5320-22430-021-00D, Detection, Control and Area wide Management of Fruit Flies. Tissue sample was taken aseptically from diseased fruit and single colony isolated. Evaluate existing papaya varieties in potential production areas currently free of Papaya Ringspot Virus (PRV). Biocontrol on Maui has been through the parasitoid but the predator has not followed the mealybug to Oahu or Hawaii. Further develop and integrate commercial-scale production strategies for managing other papaya diseases, such as Phytophthora, using breeding for tolerance and transgenic plants in the presence of the fungus. As to what extent that these clonal lineages generate sub-lineages by asexual means have yet to be determined. Papaya mealybug, originally found on Maui, was detected on Oahu in 2006 and Puna (Hawaii Island) papaya farms in 2007. If you’ve ever grown fruit of any kind, especially during spring and summer, you will know that fruit fly can be a real nuisance.
