Management of Fruit Flies (Diptera: Tephritidae) of the Most Perishable Fruits

Abstract

We investigated to minimize the dependency on the use of chemicals and thus develop safe and environmental friendly control program for the most perishable fruits i.e., apple,‘ber’, guava and mango. Our findings on the composition of fruit fly species reveal that Bactrocera dorsalis was dominant on apple (33.96% existence), Corpomya incompleta on‘ber’(51.91% existence) and Bactrocera zonata on guava (49.62% existence) and mango (74.66% existence). The correlation between population and infestation percentage was non‐significant in apple orchards, whereas positive and highly significant in between population and infestation, as well as on the cumulative basis in‘ber’, guava and mango orchards during 1998‐1999. Hoeing, baiting and methyl eugenol were statistically equal resulting about 77% decrease in infestation. The maximum control of 91.68% was observed where all four‐control operations including Dipterex® were integrated together. Weather factors, when computed together, had maximum effect on population fluctuation and infestation with rainfall contributing the major role. For guava fruits, the months of August (14.06A individuals/trap/day) and September (13.81A individuals/trap/day) were important, resulting in maximum infestation percentage of 10.76 to 14.74%, respectively.

Effect of gamma radiation on the male sterility and other quality parameters of peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae)

“…zonata was recorded for the first time in Egypt in 1998. Today, it is well established in most Egyptian provinces and it causes severe damage to a wide range of fruits such as guava, peach, mango, and apricot (El-Minshawy et al 1999;Khan et al 2005). Development of the pest's population in Egypt proves its potential to establish populations in a relative short time and to compete successfully in new environments, particularly in the Mediterranean climate (Iwahashi, Routhier 2001;Duyck et al 2004).…”

Evaluation of Using Silymarin as A Radio-Protective Agent of the Peach Fruit Fly, Bactrocera zonata Irradiated with Gamma Radiation

“…1999). Recently, it becomes a serious pest that caused a great loss of fruit productions (Khan et al, 2005). Sterile insect technique (SIT) is considered one of the successful control methods against Tephritidae species in many regions.…”

Effect of Cold Treatment as a Post-Harvest Treatment for Killing Immature Stages of the Peach Fruit Fly, Bactrocera zonata (Diptera: Tephritidae) and its Effect on Fruit Quality of Pomegranate

“…As with many tropical tephritids, B. zonata has a wide host range including apple, guava, mango, peach, and orange (Steck, 2010). B. zonata was recorded for the first time in Egypt in 1998 and established rapidly in most Egyptian provinces causes great losses in all fruit crops (Mahmoud 2004, Khan et al 2005. The percentages of apricot and citrus infested with B. zonata were higher than those infested with Ceratitis capitata and reached 20% (Saafan et al, 2005a, and b).…”
