Southern highbush blueberry plants (Vaccinium corymbosum hybrid) from a commercial blueberry farm were placed in quarantine glasshouses and either exposed to adults of the western golden‐haired blowfly Calliphora albifrontalis (Malloch) or no insects at all over a 21‐week period. Laboratory reared C. albifrontalis were regularly released into one house to maintain a population of 1000–1500 flies. Flies could only obtain sugar from the plant flowers, and there was sufficient water from the leachate fraction draining out of each bagged plant. Berries were harvested at least twice weekly from the bushes over 21 weeks (46 harvest dates), and yield (both total berry weight and numbers) recorded. Temperature and humidity were very similar between the glasshouses, and plants were irrigated daily with 2.5–4 L/plant as per the producer's recommendations. Adult C. albifrontalis required at least 1.5 flowers/fly to survive. Both more berries (17.14 kg from 9108 berries vs. 10.43 kg from 6379 berries) and larger berries (1.88 vs. 1.63 g/berry) were produced by the bushes with adult C. albifrontalis present. Mature berries are ready to pick ≈10 weeks after flower opening. This study showed that yield between the two treatments began to differ 11 weeks after the flies were first released. Berry yield remained higher in the house with flies (11.29 kg from 6177 berries at 1.83 g/berry) compared with those plants without flies (4.98 kg from 3427 berries at 1.45 g/berry. Berry size was positively correlated with seed numbers. This is the first demonstration under controlled conditions of the ability of an Australian calliphorid blowfly to pollinate and increase yield of commercial blueberry bushes.

以苍蝇Calliphora albifrontalis（Diptera：Calliphoridae）为授粉媒介的南方高灌木蓝莓（Vaccinium corymbosum）的产量

将来自商业蓝莓农场的南部高灌木蓝莓植物（Vaccinium corymbosum杂种）放在检疫温室中，在21周的时间内要么暴露于西方金毛苍蝇Calliphora albifrontalis（Malloch）的成虫，要么完全没有昆虫。实验室饲养的白。被定期放进一所房子，以维持1000-1500只苍蝇的数量。苍蝇只能从植物的花朵中获取糖分，而渗滤液中的水分则足以从袋装植物中排出。在21周内（46个收获日期）每周至少两次从灌木丛中收获浆果，并记录产量（浆果的总重量和数量）。温室之间的温度和湿度非常相似，按照生产者的建议，每天以2.5–4 L /株灌溉植物。成年C. albifrontalis至少需要1.5朵花/蝇才能生存。成年C. albifrontalis的灌木丛产生了更多的浆果（9108个浆果中的17.14千克vs. 6379浆果中的10.43千克）和较大的浆果（1.88对1.63克/浆果）。当下。开花后约10周即可采摘成熟的浆果。这项研究表明，两种处理之间的产量在果蝇首次释放后的11周开始出现差异。在果蝇中，有果蝇的浆果产量（从6.177浆果中以11.83克/浆果以11.3公斤/浆果）比没有果蝇的植物（从342​​7浆果以1.45克/浆果中以4.98公斤/浆果的浆果）高。浆果的大小与种子数量成正相关。第一个示范是在受控条件下对澳大利亚Calliphorid蝇蝇进行授粉和提高商业蓝莓灌木产量的能力。
