“…This ratio was higher than in other species of fruit fly parasitoids, such as D. longicaudata (R m = 0.14) (MEIRELLES et al, 2013) and A. pelleranoi (R m = 0.02) (GONÇALVES et al, 2016). However, it was smaller than the egg parasitoid Fopius arisanus (Sonan) (Hymenoptera: Braconidae) (R m = 0.39) (GROTH et al, 2016). According to Pedigo and Zeiss (1996), a larger value of R m indicates better adaptation of the species to a particular environment or host.…”

Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a gregarious koinobiont endoparasitoid of frugivorous dipterans. In recent years, T. giffardianus has been detected parasitizing Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in different Brazilian semiarid sites. Thus, T. giffardianus has potential to be used in the biological control of C. capitata in semi-arid conditions. However, one of the factors limiting the use of this parasitoid is the lack of detailed information on rearing methods and bioecological aspects. Therefore, the main objectives of this study were to demonstrate a rearing technique for T. giffardianus and to determine the increase in population under laboratory conditions. Specimens of T. giffardianus were obtained in the field through of the collection of fruits infested with C. capitata. The specimens obtained were used to adapt a rearing methodology for T. giffardianus under laboratory conditions. Information on demographic parameters for a T. giffardianus population was obtained using the same methodology. Based on the parameters evaluated, we found that the intrinsic rate of population increase of T. giffardianus was 0.34, the average time of one generation was 19.7 days, the population doubling time was 2.03 days and the finite rate of population increase (?) was 1.41. The demographic parameters obtained demonstrated that, with the rearing technique used, it is possible to maintain populations of T. giffardianus and enable them to multiply under laboratory conditions.

The braconid parasitoids of fruit-infesting flies have been more intensively studied from the middle to late 1990s, when taxonomic research was restarted in Brazil. At the same time, efforts toward the biological control of fruit flies intensified, and an exotic species, Diachasmimorpha longicaudata, was introduced. In the decade 2010, another exotic species, Fopius arisanus, was introduced, and two new species of Doryctobracon were described. Currently, 12 species of braconids from the subfamilies Alysiinae (two species) and Opiinae (10 species) are associated with fruit flies of economic importance in Brazil, two of which are introduced species. More than half of the species belong to the genus Doryctobracon, with D. areolatus (Szépligeti) the most widely distributed species in Brazil.

“…Adults were fed with a honey-based paste (30%) and distilled water supplied via capillarity through a sponge vegetable cloth (Spontex™), which was replaced every 72 h. Four days after parasitoid emergence, eggs of C. capitata (apx. 2500 eggs) obtained from the lab colony were deposited on a piece of filter paper (4 cm diameter) with the aid of a LabMate™ micropipette on top of a piece of sponge cloth (Spontex™) and placed in an acrylic plate (4 cm diameter by 0.2 cm tall), being offered for 6 h to females of F. arisanus (Groth et al 2016). Later, the eggs were removed and placed on a layer of artificial diet for larval development.…”

“…Later, it was introduced in various regions of Australia, Central America, and the islands of the Indian and Pacific Oceans for control and elimination of fruit flies species of the Tephritidae family (Harris et al 2007, Manoukis et al 2011. In Brazil, F. arisanus was introduced from insects obtained originally from Hawaii in 2012 by Embrapa (Brazilian Agricultural Research Corporation) in the municipality in Jaguariúna, São Paulo State, and by the Ministry of Agriculture, Livestock and Food Supply (MAPA) for biological control of carambola fly Bactrocera carambolae (Drew & Hancock, 1994) (Diptera: Tephritidae) in the State of Amapá (Groth et al 2016).…”

“…Due to its capacity of parasitism and development in eggs of C. capitata (Harris et al 2007, Manoukis et al 2011, Vargas et al 2012, Groth et al 2016, F. arisanus can be an alternative for the management of C. capitata, which is considered one of the main fruit fly species in Brazil (Malavasi et al 2000, Nava and Botton 2010, Zucchi 2015, which control is carried out with chemical insecticides (e.g., phosphorous, pyrethroids, and spinosyns) (Nava and Botton 2010). Due to the factors related to its biotic potential, polyphagy, and ability to infest a variety of native and exotic hosts (Aluja and Mangan 2008), the Mediterranean fruit fly has its occurrence reported in almost all Brazilian regions throughout the year (Malavasi et al 2000, Zucchi 2015.…”

Biology and Thermal Requirements of Fopius arisanus (Sonan, 1932) (Hymenoptera: Braconidae) Reared on Ceratitis capitata Eggs (Wiedemann) (Diptera: Tephritidae)

Fopius arisanus (Sonan) is a solitary parasitoid of eggs and the first instar larvae of Tephritidae. Due to the occurrence of Ceratitis capitata (Wiedemann) in various regions and under several climatic conditions, this study aimed to evaluate the effect of different temperatures on the embryonic development (egg-adult) and determine thermal requirements and the number of annual generations F. arisanus on eggs of C. capitata. In the laboratory, eggs of C. capitata (24 h) were submitted to parasitism of F. arisanus during 6 h. Later, the eggs were placed in plastic containers (50 mL) (50 eggs/container) on a layer of artificial diet and packed in chambers at temperatures 15, 18, 20, 22, 25, 28, 30, and 32 ± 1°C, RH 70 ± 10%, and a photophase of 12 h. The largest number of offspring, emergence rate, and weight of adults of F. arisanus were observed at 25°C. The highest sex ratios (sr > 0.75) were recorded at 15 and 18°C, being statistically higher than the temperatures 20°C (0.65), 22°C (0.64), 25°C (0.65), 28°C (0.49), and 30°C (0.47). At 32°C, there was no embryonic development of F. arisanus. The egg-adult period was inversely proportional to temperature. Based on the development of the biological cycle (egg-adult), the temperature threshold (T t) was 10.3°C and thermal constant (K) of 488.34 degree-days, being the number of generations/year directly proportional to the temperature increase. The data show the ability of F. arisanus to adapt to different thermal conditions, which is important for biological control programs of C. capitata.
