First instar larvae (early-, middle- and late-age), second instar larvae (early- and late-age), and third instar larvae (early-, middle- and late-age) of Bactrocera dorsalis and B. cucurbitae were immersed in hot water at 45.0°C in order to investigate the effect of age within each larval instar...

Background: Tephritid fruit flies are serious agricultural pests. Knowledge of the host status of different fruits and vegetables is needed in support of the development of systems approaches to facilitate commodity exports as well as to readily permit quarantine regulatory officials to assess the...

To compare relative cold treatment tolerance across the economically important tephritid fruit flies (Diptera: Tephritidae), Bactrocera carambolae Drew & Hancock, Bactrocera correcta (Bezzi), Bactrocera cucurbitae (Coquillett), four populations of Bactrocera dorsalis (Hendel), Bactrocera zonata ...

Cold storage is used to preserve fruit quality after harvest during transportation in marketing channels. Low temperature can be a stressor for insects that reduces survivorship, and cold storage may contribute to the efficacy of postharvest quarantine treatments such as irradiation against...

Modified atmosphere packaging (MAP) produces a low-oxygen (O₂) environment that can increase produce shelf life by decreasing product respiration and growth of pathogens. However, low O₂ is known to increase insect tolerance to irradiation, and the use of MAP with products treated by irradiation...

The use of vapor heat treatment (VHT) to disinfest oriental fruit flies (Bactrocera dorsalis) and melon fruit flies (B. cucurbitae) from Chinese papaya fruits (Carica papaya) destined for export to foreign countries was investigated. The tested papaya cultivar was Sunrise Solo from Hainan, China....

Bactrocera latifrons (Hendel) (Diptera: Tephritidae) is a quarantine pest of several solanaceous crops and tropical fruits that are treated using irradiation before export from Hawaii to the U.S. mainland. A dose of 150 Gy is approved as a generic irradiation treatment for tephritid fruit flies,...

Metabolic stress disinfection and disinfestation (MSDD) is a postharvest treatment designed to control pathogens and arthropod pests on commodities that combines short cycles of low pressure/vacuum and high CO₂ with ethanol vapor. Experiments were conducted to evaluate the effect of MSDD treatment...

Bactrocera latifrons (Hendel) is a pest of Asian origin, first detected in Africa in 2006. We assessed the host utilization of this quarantine pest in Morogoro region, eastern central Tanzania, by collecting a wide range of cultivated and wild host plants of species belonging to Solanaceae and...
