Therefore, the map displays assessments of the presence of this pest at the national level and in some cases at sub-national levels. In a recent study, this protein was shown to bind male pheromone components, specifically farnesene, a highly strong hydrophobic terpene. Medfly, as it is commonly known, has been recorded to infest more than 200 hosts worldwide. [3][6], Because nutrition is a crucial determinant of adult size and development, larva prefer to eat fleshy host fruit. [citation needed] Unfortunately, the infestation spread as the medfly reproductive cycle outpaced the spraying. Enrolling in a course lets you earn progress by passing quizzes and exams. Females exhibit this preference until mating occurs, following which they prefer the host fruit odor. [1] By the end of the third and final instar of the medfly, the larvae measure between 7 and 9 mm and about 8 fusiform areas.[1].

The Mediterranean fruit fly is the most stubborn of several fruit flies that have threatened California crops in recent decades. Researchers found that flies weighing approximately 8–9 mg had optimum mating success while smaller flies (i.e. in 2001, researchers were able to sequence the entire mitochondrial genome of the fly. When it has been detected in Florida, California, and Texas, especially in recent years, each infestation necessitated intensive and massive eradication and detection procedures so that the pest did not become established.

The Mediterranean Fruit Fly Ceratitis capitata (Wiedemann) The Mediterranean fruit fly ‘Medfly’ is considered one of the world’s most destructive pests. The medfly is such a widespread problem because even though it is a tropical fruit fly, it can handle cooler climates. These features include; He was advised by the state's agricultural industry and the US Department of Agriculture's Animal and Plant Health Inspection service (APHIS) to authorize airborne spraying of the region. This finding showed that the medfly has the potential to be a vector of human pathogens to fruits.

The San Diego County Agricultural Commission implemented a treatment plan, including distributing millions of sterile male flies, local produce quarantines, and ground spraying with organic pesticides. Higher concentrations of glucose and sucrose boost development and the percentage of emerging larva in comparison to high starch and maltose diets. Their diet preferences have been proven by studies in which medflies placed at the top of oranges and papayas consistently moved lower to the nutrient dense parts whereas flies placed near the bottom remained in their starting location. 1976. [23], Medflies were first detected in the region in Costa Rica in 1955. Much research has been dedicated to means of controlling the medfly.

In the instances where host fruit is plentiful in their current locations, they will not disperse beyond 300–700 feet. [1] The practices used to eradicate the medfly after its introduction into a new environment can be extremely difficult and expensive, but infestation of C. capitata will induce lower crop yields and costly sorting processes for fresh fruits and vegetables. Larvae burrow into the pulp of developing fruit. Abide by interstate quarantine rules to prevent the spread of Queensland fruit fly and Mediterranean fruit fly. Knowledge application - use your knowledge to answer a question about the origin of the medfly In short, pulp chemical properties such as acidity and soluble solid contents had little effect on larval and pupal survival but larger effects on pupal weight.

The Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann), is a key pest of fruit crops in many tropical, subtropical and mild temperate areas worldwide. It’s wide host range and tolerance of cooler climates makes it highly invasive. study 2003) Impact: Meyer CA. [5], Among fruit fly species, C. capitata has the largest variety of host-fruits, including over 200 different types of fruits and vegetables. Another important location for copulation is on the fruit itself during the late morning or early afternoon.
