Effectiveness of Fruit Bagging for the Control of Insect-Pests Complex and its Impact on Quality of Mango Fruits

Abstract

Mango (Mangifera indica L.) is famous among all fruits because of its taste, variety and color. However, the quality of mango fruits is mainly deteriorated by insect-pests complex. The study was performed to evaluate bagging effects on insect-pests complex, yield and quality of mango fruits at private mango orchards located in Multan district. A mango cultivar, Anwar Rataul was selected, and the fruits were bagged during 1st week of May (at stone size stage) to 1st week of July 2017 (at maturity stage). The results indicated that the attack of fruit flies and other insect-pests complex were zero in bagged fruits. It was further recorded that the maximum average fruit weight i.e. 203.50 g was noted in those where butter paper bag was wrapped as compared with brown paper bagged fruits having 197.83 g and un-bagged fruits with 159.50 g per fruit. However, brown paper bag resulted in better fruit color development. Similarly, average fruit lengths were greater i.e. 91.33 and 90.18 mm in butter paper and brown paper bagged fruits, respectively as compared to 85.33 mm in un-bagged fruits. Bagged fruits had higher total soluble solids and slightly lower titratable acidity as compared to un-bagged fruits. Further, bagged fruits had no cracks, sunburn, mechanical injury, bird damage, skin blemishes and agrochemical residues. So, it is concluded that fruit bagging on mango cv. Anwar Rataul trees at stone size stage proved to be an effective practice against insect-pests complex and for quality production of fruits for export purposes.

Influence of Pre-Harvest Bagging on the Incidence of Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) and Fruit Quality in Mango

“…), we found that bagged mangoes were 9.6% (cloth bags) and 11.1% (paper bags) heavier than controls but only by about 3% greater in volume, given that sphericity was not different among the treatments (Table 2). These results are consistent with those previously reported by several authors who indicated that bagging increases fruit weight and total yield [17,24,29,35,39,40].…”

“…Hoffman et al [16] also described an increase in the skin area with yellow color and a decrease in reddish area in Keitt cv., whereas Anwar Rataul cv. fruits bagged with brown paper bags showed a more yellowish color than control or butter paper bags [40]. Finally, Wu et al [41] found that lightness and chroma were remarkably higher, while hue angle was significantly lower than controls, and that a single white bag could be a promising practice for improving coloration.…”

Metabolomic Insights into the Browning of the Peel of Bagging ‘Rui Xue’ Apple Fruit

“…Bagging can promote fruit coloring and improve fruit surface smoothness. In addition, bagging can also reduce the direct pollution of pesticides, dust, and prevent diseases and attack by pests and birds [17]. Bagging has become an important technique in the production of high-quality and pollution-free fruits.…”

Overview and future research needs for development of effective biocontrol strategies for management of Bactrocera dorsalis Hendel (Diptera: Tephritidae) in sub‐Saharan Africa

“…These ‘push‐pull’ strategies largely involve the use of nonlethal materials to conserve parasitoids and the weaver ant species ( Oecophylla spp.) against fruit flies in fields 149–155 . On the other hand, zero tillage, including application of weedicides, will conserve EPNs in soils because EPNs are not generally affected by pesticides, except some nematicides 156 .…”

“…Bagging fruits on trees reduces exposure of fruits to fruit flies and pathogens [e.g. anthracnose disease‐causing Colletotrichum gloeosporioides Penzig & Saccardo (Glomerellales: Glomerellaceae)] 153,154,161 . The latter is a destructive fungal pathogen that reduces fruit set, increases premature fruit drop and/or causes blemish to quality of fruits in many countries across SSA (authors' personal observations).…”
