Dacus cucurbitae ( Diptera: Trypetidae) attacks  on cucumber and peria fruits wrapped at cherelle stage. The fruit flies were important pests of cucumber (Cucumis sativus L) and peria (Memordica charantia L.).  The flies attacked fruits by laying egg on the fruit surface and their developing immatures caused serious damages from the inside. The objective of this experiment was to determine the effect of the  fruit wrapping at cherelle stage  on fruit fly infestation on  cucumber or peria fruits.   The experiment was conducted in villages of Terbanggi Besar (Central Lampung) and Jati Agung  (South Lampung) during October—November 2001. A set of cherelle stage fruits, i.e. those just shed off their florescence, were wrapped using plastic bags while another set of adjacent fruits were left unwrapped. Fruits (treated or untreated) were taken soon after they fell off or at their normal harvest time, whichever came first, then were weighed and incubated in the laboratory to observe the fruit fly emergence.  The results showed that fruit wrapping significantly reduced the fruit fly infestation and suppressed the fruit fly population on cucumber or peria fruits. The wrapped fruits weighed more than unwrapped fruits

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.

<p>Fruit flies attack mostly on fruit vegetables and fresh consumed fruit. Symptoms of damage is decaying of fruit surface resulting to fruit falling. Data on the diversity of fruit fly species in South Sumatra and their patterns of presence have not been widely reported. The aim of the research was to study diversity and presence patterns of fruit flies based on the host and trap. The research was conducted using a survey method in 9 cities and districts in South Sumatra Province. Fruit flies were collected by collecting infected fruit and using traps containing cue lure (CL) and methyl eugenol (ME). There were 24 types of plants observed, including fruit, vegetables, and fruit for consumption. Fruit flies identification was carried out by observing external morphological characteristics. The identification resulted 18 species in which CL and ME trap 10 and 7 species, respectively. One species (Bactrocera latrifons) did not trapped in both traps. Among 18 species, 7 of them were obtained from fruit collections. The type of attractant affected species diversity and number of fruit flies caught. B. latifrons was only found in fruit rearing. The altitude of observation area affected fruit flies diversity. All species were found in the lowlands, except B. ascitus, B. cilifera, and B. latrifons. In the moderate lands and highlands, the number of fruit fly species found was less than in the lowlands.</p>

Fruit bagging is an important strategy to protect fruit against fruit fly (Tephritidae) infestation and pesticide contamination. In laboratory, we compared the forced infestation of guavas by Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) when wrapping them with non- woven fabric (NWF) bags. The combined repellence and protection effects of white, green, blue and red NWF bags were tested in comparison with un-bagged guavas. Bagged fruit with the NWF tissue stuck to the pericarp were separately exposed to both fruit fly species for 48 hours, with a ratio of 10 females per fruit inside of laboratory cages. In C. capitata, the number of pupae per fruit was significantly higher in the green NWF bags, and the infestation in the other colour bags were similar to the control group (non-bagged). In A. fraterculus, guavas with red NWF bags had significantly higher infestation (205.42 pupae per fruit) than fruit that received the other colour bags White and blue bags were less attractive for oviposition from both fruit fly species. The adherence of the NWF bags to the fruit surface causes egg-laying of fruit flies.
