Knowledge of the population fluctuation of a pest in an orchard allows the producer preventing and making use of techniques that control the insect pest before it causes economic damages. The objective of the present work was to verify fruit fly species population dynamics in a commercial of Psidium guajava L. (Myrtaceae) orchard in the Curimataú microregion of Paraíba, also to characterize the community of fruit flies through faunistic analysis as well. Fruits were collected biweekly, the total was 24 collections between August 2014 and July 2015 in the municipality of Nova Floresta-PB. Fruits were preferentially collected mature or at the beginning of maturation, differentiating fruits harvested on the soil, plants, and through PET traps containing different food attractants. After collection, fruits were kept in plastic trays filled with a layer of two centimeters of sterilized sand and covered with fabric ‘voil’. The trays were labeled with the field data and placed in a greenhouse. Past the period of 15-25 days the fruits, already in the stage of decomposition were examined in order to collect pupae and larvae of 3rd instar. A total of 462 specimens of fruit flies were collected in 12 months sampling period, they were collected from fruits gathered from the ground and from the tree, and through trapping, being 209 males and 253 females, all collected in P. guajava. From the results obtained during the sampling period, a total of four species were recorded by fruit collection and six species by a trap. A new specimen of Anastrepha was found that there was no register in Paraíba yet, Anastrepha hadropickeli Canal, Uramoto and Zucchi (2013), as well as a Rhagoletis sp. (Loew).

Guava (Psidium guajava L.) presented prominence among the tropical fruit.  Guava exports are still unimpressive, because of the quarantine pests, among them the fruit flies.  The present research had as objective to evaluate the population fluctuation of fruit flies Anastrepha spp. and the fruits infestation caused in guava accesses cultivated in organic system, and study the possible correlations between this pest and meteorological factors.  To estimate population fluctuation, 20 yellow sticky traps were used.  The reviews were initiated in April 2013, for 378 days.  The traps were kept in the field for the entire duration of the experiment, and they were reviewed every 14 days in most cases, during replacement of traps for new ones.  With the data, simple correlations were calculated between the fruit flies of the genus Anastrepha spp., the temperature, and precipitation.  Nine fruits per accession, at the stage of maturation, were taken to the laboratory and evaluated for fruit fly infestation by the longitudinal cutting of fruit. The averages were compared by the Scott-Knott test at 5% probability.  The genus Anastrepha was found in greater quantity, and there is no correlation between the meteorological factors and population fluctuation of Anastrepha.  Also was found some individuals of the species Ceratitis capitata.  Most of the fruits of the evaluated accesses presented high infestations by fruit flies.  Accesses IAC – 4 – Cica noteworthy for not presenting any infested fruit, without differing from accesses Taquaritinga Comum, both red.  The accesses Torrão de Ouro, Supreme BA, L2P4, and Supreme, also showed low numbers of fruit attacked.

The oriental fruit fly Bactocera dorsalis (Hendel) is an important pest of snake fruit (Salacca zalacca) in Sleman District. Due to the high level of damage by the fruit flies, it is necessary to do. The aim of this research was to find out suitable fruit traps, by testing the oviposition preferences of the fruit flies in the orchard to lay eggs on several types of fruit. The research was done in snake fruit orchard located at Sleman Yogyakarta and owned by farmers, while the Lab works were done at the Laboratory of Entomology, Department of Plant Protection, Faculty of Agriculture, Universitas Gadjah Mada. All researches were done between April-June 2019. Guava (Psidium guajava), watery rose apples (Syzygium aqueum), starfruit (Averrhoa carambolae), and snake fruit (Salacca zalacca) were used as trap crops. Each fruit, with the same maturity level, was hung 1.5 m above the ground for 4 days with 12 days total trapping at intervals of 3 times. After the test, each fruit was taken and the insects in it were reared in the laboratory. The number of pupae and flies that emerged from each fruit was counted and compared. The results showed that in the orchard 1 as well as  2, of guava fruit produced the highest number of (151 pupae) followed by salak (94 pupae), star fruit (83 pupae), and water guava (2 pupae). The finding of seeds shows that guava fruit is the most suitable host for the fruit flies to be used in the trapping, followed by star fruit and watery guava.

In Nigeria, published information on the range and relative importance of different pests on cucumber is scanty. Studies were therefore carried out in a survey to determine the insects associated with cucumber, and on-field to quantify insect induced damage at different crop growth stages. Surveys were carried out in five cucumber fields each at Ibadan, Oyo State, and Abeokuta, Ogun State, Nigeria. In the field experiment, cucumber plants were protected at different stages: pre-flowering, flowering, post-flowering/fruiting, or all growth stages with lambd-acyhalothrin sprayed weekly at 25ga.i/ha. The control plots were without insecticide protection. Insects recorded from the surveys included: Zonocerus variegatus, Podagrica uniforma, Aphis gossypii, Myzus persicae, Bemisia tabaci, Thrips tabaci, Epilachna chrysomelina, and fruit flies Bactrocera invadens and Dacus ciliatus. Other insects found were Cheilomenes lunata and Chelisoches flavipennis, which are natural enemies of whiteflies and aphids, respectively, and the honey bees, Apis meliferae, which is a pollinator. Significantly higher number and heavier fruits, which were not statistically different from those recorded in full protection plots, were produced when cucumber was protected at post-flowering stage. Fruit fly damage in unprotected plots was 60% and 55%, while that of the Epilachna beetle was 55% and 46% in 2004 and 2009, respectively. Yield was significantly higher by 50% in plots sprayed at post-flowering stage over the control. Epilachna beetle and the fruit flies attacking at the post-flowering/fruiting stage are therefore, important in cucumber production, and the fruiting stage is the most critical where insect pest control measures must be applied.

Fruit flies are considered an important fruit pest for world fruit production because they cause significant losses to the production and limit fruit free transport due to quarantine restrictions imposed by importing countries. Fruit flies population dynamics knowledge of a particular region is an important factor in the management of this pest. Traps are devices created to attract and capture flies by sexual attraction or food attraction, both put inside the trap. It reduces fruit flies population in the orchard, decreasing the pressure and chances of an infestation. This research aimed to evaluate the efficiency of food baits in the fruit flies capture on guava plant culture, in order to establish an adequate program for this pest in the municipality of Nova Floresta – PB. Monitoring of the adult fruit-fly was performed with aid of plastic traps of the type PET bottle 330 mL of Bio Anastrepha® 5.0%, 440 mL of sugarcane molasses diluted to 10.0% and 520 mL of 30.0% fruit juice (guava). The traps were installed in the central part of the trees, approximately 1.50 m above ground. Every 15 days adult fruit flies were caught, the occasion that food baits were replaced. From these data were evaluated: efficiency of food baits, MAD index (flies/trap/day) and food baits cost-benefit analysis. The best food attractant at the lowest cost was Bio Anastrepha® at 5.0%, with a catch margin of 63.83%, followed by fruit juice at 30.0% and sugarcane molasses at 10.0%, with 34.04% and 2.13%, respectively.

Guava (Psidium guajava L.) fruit is a popular nutritious dessert in Sudan. It is famous for its medicinal values as a prompt cure for digestive disorders and respiratory ailness this besides being a rich source of C vitamin. This fruit is highly amenable to fruit fly attack and it is a harbor of eggs of five different species [Ceratitis capitata Wied.; Ceratitis quinaria Bez.; Ceratitis cosyra Wlk.; Bactrocera invadens De Trusta and White and Bactrocera zonata (Saunders)] in Sudan. This is stimulating to a chain of endless research to combat these notorious pests which account for huge losses in this crop that reach up to 80% or even more. This research aimed at evaluating the effect of oil coating on fruit fly infestation and the quality indexes in guava fruit using five different botanical edible oils. The results showed that groundnut (Arachis hypogaea L.) (GNO), sesame (Sesamum indicum L.) (SO), baobab (Adansonia digitata L.) (BO), olive (Olea europaea L.) (OO) and neem (Azadirachta indica A. Juss) (NO) oils effected a corrected disinfestation of 80, 72, 56, 52 and 28% in test fruits brought from Kadaro orchards North Khartoum, respectively. The corresponding average readings of maggots in infested fruits were 4, 17, 11, 5, 7 and [10 (for the first 4) and 26 for NO] in the control. Two essential quality indexes were checked in test fruits which included fruit color (FC) and firmness (FF). The corrected test readings reflected 64, 80, 44, 52,-4 and [8 (for the first 4) and 20 for NO] in the control sustained FC for GNO, SO, BO, OO, NO and the control, respectively. However, the corresponding readings for FF were 3 (medium) for all oils and 4 (soft) for the controls. These results reflect a potent and the best efficacy of peanut and sesame oils, of the five test oils, in controlling fruit flies in guava and extending its shelf life.

Abstract: Fruit flies are among the main groups of phytophagous insects. Their larvae, when feeding on the pulp or seeds of the host fruits, can cause rot and favor the entrance of pathogens. Thus, the objectives of this study was: (1) To know the trophic associations between species of parasitoids and fruit flies in the Parque Nacional da Serra da Bodoquena (PNSB)-MS, Brazil. (2) To inventory the parasitoid species associated with fruit flies in fruit trees in the Parque Nacional da Serra da Bodoquena. Monthly expeditions were carried out (From Jan 2017 to Feb 2018) in order to collect the fruits and obtain the fruit flies (Tephritidae) and their respective parasitoids. The collected fruits were transported to the laboratory of frugivorous insects (LIF) of the Universidade Federal da Grande Dourados (UFGD)-MS. The fruit fly larvae were daily collected and placed in transparent acrylic cups containing sterilized sand, where they remained till the emergence of adults and their parasitoids. Twenty-Three adult Tephritid parasitoids were recovered, represented by two species of Braconidae: Doryctobracon areolatus (18) and Utetes anastrephae (5), both infesting Anastrepha species: Anastrepha fraterculus, A. sororcula and A. striata in Myrtaceae: Psidium guajava and Eugenia myrcianthes. Doryctobracon areolatus and Utetes anastrephae are reported for the first time parasiting Anastrepha species in Eugenia myrcianthes.

South American Fruit Fly

Abstract Anastrepha fraterculus the South American fruit fly, is an important insect pest in apple orchards of southern Brazil, especially in small farms, where it often causes total crop loss. Experiments were conducted to evaluate, during four crop seasons (2009/2010, 2010/2011, 2012/2013, and 2013/2014) in organic and conventional apple orchards in southern Brazil, the toxic bait formulation ANAMED™ (oils and waxes 49.0% + M7 attractant 24.2% + spinosad insecticide 0.1%) for its capacity to reduce the South American fruit fly population. ANAMED applications started after apples with an average diameter of 20 mm had been thinned, and they were made every 14 days until harvest. ANAMED was sprayed on non-crop vegetation growing on the edges of the orchards at a rate of 1.0 kg.ha-1. Adult fruit flies were monitored weekly using McPhail traps baited with Torula™ yeast. Injured fruits were evaluated seven days before harvest. ANAMED reduced the adult population of trapped fruit flies captured in all crop seasons and the injured fruit, except for the first year of evaluation (2009/2010). In conclusion, the sequential use of ANAMED toxic bait over time significantly reduced adult populations of A. fraterculus and the percentage of fruits injured by this pest.

Symbiotic Associations

AbstractTephritidae is a large family that includes several fruit and vegetable pests. These organisms usually harbor a variegated bacterial community in their digestive systems. Symbiotic associations of bacteria and fruit flies have been well-studied in the generaAnastrepha, Bactrocera, Ceratitis,andRhagoletis.Molecular and culture-based techniques indicate that many genera of the Enterobacteriaceae family, especially the genera ofKlebsiella, Enterobacter, Pectobacterium, Citrobacter, Erwinia,andProvidenciaconstitute the most prevalent populations in the gut of fruit flies. The function of symbiotic bacteria provides a promising strategy for the biological control of insect pests. Gut bacteria can be used for controlling fruit fly through many ways, including attracting as odors, enhancing the success of sterile insect technique, declining the pesticide resistance, mass rearing of parasitoids and so on. New technology and recent research improved our knowledge of the gut bacteria diversity and function, which increased their potential for pest management. In this review, we discussed the diversity of bacteria in the economically important fruit fly and the use of these bacteria for controlling fruit fly populations. All the information is important for strengthening the future research of new strategies developed for insect pest control by the understanding of symbiotic relationships and multitrophic interactions between host plant and insects.

Guava (Psidium guajava L.) is a lovely tropical and subtropical fruit that originates in Mexico, Central America, and then taken to other distant and near parts around the world. In Sudan this popular fruit is produced in orchards and household and is so profitable but yet attacked by a lot of fruit fly species of the Genera Ceratitis and Bactrocera and the result is a loss of more than 70%. This research aimed at evaluating the effect of Gum Arabic coating (GAC) in extending the shelf life of guava fruit and disinfesting it from these notorious pests. Guava fruits from Kadaro orchards, Khartoum North, were tested using seven concentrations of Gum Arabic solutions. The results reflect that 1: 4 (25%) and 1: 8 (12.5%) (GA: water) concentrations attained 56 and 40% disinfestation, respectively whereas the other lower concentrations effected corresponding results in a range from 20 – 08%. The reduction in maggots per test fruit reached upto 188% as compared to the control.  The highest concentrations (1: 4 & 1: 8) effected a sustainability of 52% in fruit firmness (FF) with an average of medium (3) FF compared to soft FF (4) in the control. The corresponding results in other lower concentrations (1: 16; 1: 32; 1: 64; 1: 72 & 1: 96) were 36, 24, 24, 20 and 16%, respectively. In addition to an average FF of 4 (soft) for all these concentrations and 5 (very soft) for all the corresponding controls. Nevertheless, the sustainability of fruit color (FC) effected by the test concentrations was 52, 44, 24, 22, 24, 20, and 24%, respectively. Regarding these results, the two highest test concentrations effected a sizeable disinfestation and control of fruit flies and a good extension of shelf life of guava in Khartoum State. These findings support using this treatment as an effective IPM tool to extend guava fruit shelf life and upgrading its postharvest quality.
