Effective chemical control of fruit flies (Diptera: Tephritidae) pests in mango orchards in northern Côte-d’Ivoire

Abstract

Fruit flies are major pest in West Africa. In Côte-d'Ivoire, they caused heavy losses. Thus, preventive measures are taken to reduce their damage. The objective was to evaluate the effectiveness of Success Appat ® and Proteus 170 O-TEQ against fruit. Traps baited with sexual attractants were set in mango orchards and their contents were collected each week. Bait and insecticide were renewed each month. Three orchards were treated with Success Appat ® and three with Proteus 170 O-TEQ, respectively and their untreated orchards were selected. Mangoes were collected in treated and untreated orchards to assess the attack and infestation rates of orchards. Eight species of fruit flies were recorded. Bactrocera invadens was highly captured in different orchards. Orchards treated with Success Appat ® have a lower rates of attack (11.7 ± 3.52%) and infection (02.32 ± 1.6 pupae/ kg.f) than the untreated orchards, (41.05 ± 7.6%) and (34.4 ± 8.18 pupae/ kg.f), respectively. Equally, orchards treated with Proteus 170 O-TEQ showed lower rates of attack (13.59 ± 5.38%) and infection (05.86 ± 4.08 pupae/ kg.f) than untreated (47.37 ± 10.95%) and (44.72 ± 15.64 pupae/ kg.f), respectively. Insecticides Success Appat ® and Proteus 170 O-TEQ significantly reduced the damage of fruit flies in orchards.

Interactions between Two Parasitoids of Tephritidae: Diachasmimorpha longicaudata (Ashmead) and Psyttalia cosyrae (Wilkinson) (Hymenoptera: Braconidae), under Laboratory Conditions

“…In response to enormous losses incurred in the horticultural agro-industry, programs aimed at managing fruit damaging Tephritidae have been implemented worldwide, albeit with variable success. Some of the strategies that have been used widely include chemical control [ 11 , 12 ], orchard sanitation [ 13 , 14 ], baiting techniques [ 15 , 16 , 17 , 18 ], sterile insect technique [ 19 , 20 , 21 , 22 ], male annihilation technique [ 18 , 23 , 24 , 25 ], entomopathogenic fungi [ 26 , 27 , 28 ] and use of parasitoids [ 29 , 30 , 31 ] among others.…”

Morphological, Physical and Biochemical Characteristics of the three Main Varieties of Mango (Mangifera indica L.) Cultivated in the Poro Region (North of Côte d'Ivoire)

“…The majority of studies previously carried out on mango in Côte d'Ivoire had focused on mango diseases and pest attacks [9,10,11,12,13,14,15,16,17,18]. The distribution of mango varieties in orchards was also investigated [19], as well as the influence of harvest time on the quality and ripening of Kent mango variety [20,21].…”

Influence des supports alimentaires sur quelques paramètres biologiques de <i>Bactrocera dorsalis</i> (Hendel) et de son parasitoïde <i>Fopius arisanus</i> (Sonan) en conditions de laboratoire

“…Ainsi, en raison de leur statut d'insectes de quarantaine, d'énormes pertes ont été enregistrées lors des exportations vers l'Union Européenne (Parrot et al, 2018). Les espèces de mouches des fruits, d'importance économique, les plus abondantes dans les vergers de nombreux pays d'Afrique de l'ouest sont B. dorsalis (Hendel) et Ceratitis cosyra (Walker) (Amevoin et al, 2009 ;Ouédraogo, 2011 ;N'depo et al, 2015). Pour réduire les dégâts de ces mouches, des méthodes de lutte variées ont été envisagées en intégrant la lutte biologique (Ouédraogo, 2011 ;N'depo et al, 2015).…”

La lutte biologique fait l'objet d'un grand intérêt dans de nombreuses études car elle est l'une des composantes essentielles de la lutte intégrée et elle représente une approche agro-écologique (Gomina, 2015 ;Konta et al, 2015 ;Hintenou et al, 2016), c'est-à-dire respectueuse de l'environnement et viable sur le long terme.…”
