DescriptionTop of page
Laid in mucilage-covered groups of 10-200, initially light-green, becoming yellow; oval to round, flattened and scale-like, 1 mm x 0.6 mm, with a reticulate chorion.
The larva is illustrated in detail by Carter (1984).
Initially yellow with a black head which becomes brown in the 2nd instar. In the last (7th) instar, which attains 20 mm in length, the head is brownish-yellow with variable dark spots. The prothorax is a greenish-yellow with four dark spots on the posterior margin. The abdomen is yellow, olive green or grey-brown, depending on diet.
For more information see Pandolfo and Zagami (1983) and van de Vrie (1991).
Initially brown, becoming almost black. The cremaster has four pairs of hooks. In addition to two rows of dorsal spines, the abdominal segments possess numerous yellow bristles.
Wingspan 15-17 mm in males, 18-24 mm in females, forewings rectangular, yellowish-brown to purplish-brown in colour with two (in males, one in females) narrow, darker, obliquely transverse bands. Hindwings orange with dark-brown edges. Colour tones vary widely between individuals, females being generally lighter than males.
DistributionTop of page
C. pronubana is indigenous to the Mediterranean region.
C. pronubana was previously considered a quarantine pest for Israel (D Opatowski, Plant Protection and Inspection Services (PPIS), Israel, personal communication, April, 2006). Records of presence (e.g. Bodenheimer, 1937 cited in Wysoki and Izhar, 1976; Wysoki, 1989; Swirski and Wysoki, 1995) were thought to be based on a misidentification. However, the pest found on avocados in Israel has now been identified as C. pronubana, confirming its presence in the country (D Opatowski, Plant Protection and Inspection Services (PPIS), Israel, personal communication, December, 2006).
A record of C. pronubana in Japan (Carter, 1984) published in previous versions of the Compendium is erroneous. Carter (1984) quotes CIE (1975) in his description of C. pronubana but there is no record of this species in Japan in CIE (1975) or CABI/EPPO (2014) and C. pronubana is not mentioned in A Guide to the Lepidoptera of Japan (Komai et al., 2011).

Host Plants and Other Plants AffectedTop of page
Growth StagesTop of page
SymptomsTop of page
Terminal and axial leaves and buds are enclosed in silk and eaten, becoming typically crooked; this is usually more serious in spring.
On carnation flowers
The buds are penetrated by the larvae; petals may be joined by larval silk, thus hampering opening and giving flowers a characteristic swollen appearance. In some cases, it may not be apparent that flowers are infested.
Foliage attack is similar to that described for carnations, with typical crooked growth (Delucchi and Merle, 1962). Young stems may be mined. On fruit, there are two types of damage. In April to July, the larvae penetrate the young developing fruit, feeding superficially on the skin at the peduncle base. The larvae then move up the fruit and continue to consume the skin while protected by leaves which they have spun together with silk. The pulp is never attacked and the damaged mesocarp quickly suberizes. This results in light-brown to blackish patches on the fruit surface, reducing marketability. The second type of damage is that on ripe fruit, attacked in October to November; the calyx end is not usually affected, and damaged areas do not suberize, so favouring the development of rots.
For more information, see Targe and Deportes (1961) and Balachowsky (1966).

Biology and EcologyTop of page
In southern areas (Spain, Italy), four generations are the rule; third and fourth generation larvae overwinter, those in glasshouses (with minimum temperature 8°C, for example, for carnations) emerging around April, about 15 days earlier than those on crops in the open air. In North Africa, on citrus, there are at least five, and probably six, generations annually.
In glasshouses (with minimum temperature 15°C, for example, for roses), more than five generations may develop each year, and all stages of the insect may be found between spring and autumn, although in the south of France the periods of egg laying and appearance of first generation adults never overlap. Adults are chiefly day-flying, especially in morning sunshine.
Imagoes usually hatch at night and copulation, lasting 1-2 h, takes place immediately. The large-bodied females cannot fly easily and only males are normally active. Egg laying occurs in batches, beginning 3-4 h after copulation, and is spaced out over several days. Eggs are laid on smooth surfaces, especially glass, the first batch, usually of 150-250 eggs, being the most important. Each female can lay up to 700 eggs (average 430).
Eggs hatch after 6-22 days (van de Vrie, 1991). The larvae emerge within a few seconds and, being positively phototactic, quickly move or are carried in wind to the young growing points or flowers. Here, they spin silk around two to three terminal leaves or petals, and feed on the upper surface, so making numerous holes; the parenchyma may be mined. By the end of the third larval instar, the whole leaf is attacked and surrounded by a dense silken mass.
Hatching to pupation (seven larval instars) takes 19-70 days, and pupation itself 4-30 days (van de Vrie, 1991). Longevity of imagoes is about 11-12 days for females and 14-18 for males. Temperature thresholds for copulation, egg laying and hatching are 10.5, 12-13 and 14°C, respectively. Pupae cannot survive 2 h at -4°C, and are therefore of no importance in overwintering. At average temperatures of 15 and 30°C, the complete life cycle takes 123-147 and 28-44 days, respectively. Humidity is an important factor with respect to mortality; larvae can develop at 10-15% RH; 70-90% RH (van de Vrie, 1991) is optimum but, above 90% RH, larval and pupal mortality is increased. For more information, see Fisher (1924), Bestango (1955), Balachowsky (1966).
Means of movement/dispersal
The adults can disperse themselves locally. In international trade, C. pronubana may be carried on plants for planting or cut flowers of carnations, chrysanthemums, pelargoniums, roses and other host plants.

Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.Control of C. pronubana can be achieved by using pyrethroids such as deltamethrin and fenvalerate (Pandolfo and Zagami, 1983; Inserra et al., 1987). Control of C. pronubana by biological means has not been fully investigated. Monitoring of C. pronubana populations is carried out by sex pheromone traps, but their use as a direct control agent by means of mating disruption is still being questioned (Guda and Capizzi, 1988).
Burgess and Jarret (1978) studied the effect of Bacillus thuringiensis on C. pronubana in glasshouses but found that a higher than normal dose was necessary for effectiveness. Wysoki (1989) tested its effect in Israel where the moth is a pest of avocados. Pheremones have been used extensively for monitoring populations, details are given in Quaglia (1993).
EPPO recommends (OEPP/EPPO, 1990) that, in countries where C. pronubana occurs, nursery inspections should be carried out during the growing season prior to dispatch.
Baraldi (1996) stated that experimental research on the use of direct ionizing radiation (radiodisinfestation) to control insect pests on cut flowers has given promising results.
