| Abstract | ||
| The infestation level with the peach fruit fly (PFF), Bacterocera zonata and the Mediterranean fruit fly (MFF), Ceratitis capitata on different mango varieties (early mature “Hendy & Founs”, moderate mature “Zebdia & Awyesy” and late mature varieties “Fagrklan & Kent") were studied at Abosoyr district, Ismailia governorate, during two successive seasons (2014 and 2015). Results indicated that the percent of infestation with B. zonata in early mango varieties “Hendy & Founs” and moderate mango varieties “Zebdia & Awyesy” was high, while it was low in late mango varieties “Fagrklan & Kent” during the two successive seasons. Total numbers of natural fallen fruits in early mango varieties “Hendy & Founs” were more than the other varieties (moderate and late mature varieties) during the two successive seasons (2014 & 2015). Also, the average numbers of infested fallen fruits in early mango varieties “Hendy & Founs” were more than that of the other varieties (moderate and late mature varieties) during the two successive seasons (2014 & 2015). The percentage of infestation descendingly arranged according to different reasons such as susceptibility of variety to infestation as follows: early mature, moderate mature and late mature varieties during the two successive seasons, respectively. The percentages of infestation with B. zonata were (95.8 & 93.0), (90.3 & 88.1) and (85.6 &76%).While, thatrecorded byC. capitata were (4.2 & 7.0), (9.7 & 11.9) and (14.4 & 23.2%) for the three tested varieties (early, moderate and late varieties) during the two successive seasons, respectively. Statistical analysis showed significant and high significant differences between the percentages of infestation by B. zonata and C. capitata of the three tested varieties (early, moderate and late varieties) during the two successive seasons. The weather factors (max. and min. temperatures as well as relative humidity) affected % infestation of fallen fruits of mango trees with B. zonata and C. capitata during the two successive seasons (2014 & 2015). During first season, fruit infestation was positively significant with min. temp. and relative humidity for early and moderate varieties. While, during the second season, infestation of early varieties was positively significant for max. temp. But, it was significantly negative for relative humidity. Infestation of moderate mango variety positively and significantly correlated with max. temp. Therefore, the late mango varieties were insignificantly affected with weather factors during the two successive seasons. | ||
