Ceratitis capitata, Med Fruit Fly
The Medfly Ceratitis capitata is described as the most economically important fruit fly worldwide. In the Mediterranean Basin countries alone, its economic impact is estimated to caused losses of approx. USD 190 million every year.
Ceratitis capitata is prevalent in many parts of the world: across most of Africa, South Europe and South America and a total of 132 countries and groups of islands worldwide.
Female Medfly pierce the skin of fruit to lay 1-10 eggs around 1mm beneath the surface. Several females may use the same deposition hole so more than 75 eggs could be clustered in one fruit. Eggs hatch and larvae begin eating and forming tunnels. The damage occurs in stages as seen below. Secondary organisms such as bacteria and fungi gain access through the holes and cause decomposition to the plant tissue as an indirect result of the attack.

Field experiments were conducted using Russell IPM’s Ceranock bait station, “attract and kill” system to combat Mediterranean fruit fly, Ceratitis capitata, in citrus orchards of Baghdad and Wasit governorates, Iraq, during 2013-2014 season. The total trapped insects after two weeks of Ceranock were 59, 94, 142 and 205, 277, 765 adults for the firsst, second and the control orchards in the two locations, respectively. The results of this study demonstrate clearly the efficacy of Ceranock bait station, “attract and kill” system as a control measure for Medfly in citrus orchardsRead more

Field-evolved resistance to lambda-cyhalothrin has been found in C. capitata. Metabolic resistance mediated by P450 appears to be the main resistance mechanism in the resistant strain W-1Kλ. The levels of cross-resistance found may compromise the effectiveness of other pyrethroids for the control of this species. The withdrawal of malathion in the European Union in 2009 resulted in a large increase in lambda-cyhalothrin applications for the control of the Mediterranean fruit fly, Ceratitis capitata, in Spanish citrus crops. Therefore, more biorational control strategies should be considered.Read more
Bouagga, S. et al. 2014 Evaluation of an “Attract and Kill” System to Combat Ceratitis capitata on Peach Trees in Tunisia. Journal of Agricultural Science and Technology A 4 (2014) 612-619
Attract and kill (AK) technology was evaluated against the Mediterranean fruit fly (Med-fly), Ceratitis capitata W.. Treatment was carried out in two peach orchards of four hectares each; first one located in Borj-Touil and the second in El-Kssibi Mornag, Northern Tunisia during the 2012 field season. AK is a specialized system based on hydrolyzed proteins and alpha-cypermethrin. During this study, 400 AK bait stations were placed in every hectare, four weeks before fruits color changes. The tested AK system was found effective in reducing the number of C. capitata population to 70% comparing to the untreated orchards. Fruit damages assessment showed significant differences between treatments in respect of decreasing infestation onto fruits. Study results indicated that AK baited treatments were able to reduce dropped and soften fruits infestation seven times than that of control plots. Fruit damages were restricted to 4%-5% in treated areas with AK system in compare to 31%-35% recorded in controlplots. This novel AK system showed good performance to combat Med-fly and can be successfully used to combat various fruit fly species when applied for an area wide application program.Read more
