In the Indian subcontinent, largely cultivated evergreen tree is Jamun, Syzygium cuminii (L.) Skeels. The seeds of jamun have a wide variety of pharmacological qualities making them much more valuable. Seed weevil (Curculio c-album Fabricius) and Eulophid wasp (Anselmella kerrichi) both are damaging to seeds. C. c-album caused up to 100 % fruit damage in a few varieties of jamun. Fixed plot surveys were carried out at Horticultural Farm, Anand Agricultural University, Anand during, 2022 and 2023 in jamun orchard to find out the damaging pest of jamun seed. Small, black to brownish color adult beetle with entire body bear golden yellow color scale found during the survey and identified as Curculio c-album. First time in Gujarat this pest was observed to damage on fruits of jamun and cause economic losses. Both adult and grub caused damage to jamun. It causes 48.0 and 62.0% fruit damage at ripening stage of jamun during 2022 and 2023, respectively, and makes it unmarketable.

This experiment was carried out at Kittur Rani Channamma College of Horticulture (KRCCH), Arabhavi, UHS, Bagalkot, Karnataka, India, from January to December during 2021 and 2022. The study orchard comprised of nine years old AJG-85 and Konkan Bahadoli jamun varieties. Observations on sucking insect pests and bark eating caterpillar were recorded. Among the sucking pest, shield back bug was noticed throughout the year. Tea mosquito bug incidence prevailed from I fortnight of January to I fortnight of May and again it was observed from November I fortnight to December II fortnight in both varieties. Whitefly incidence was noticed from I fortnight of February to I fortnight of May and II fortnight of November to II fortnight of December in AJG-85 and where as in Konkan Bahadoli whitefly incidence was observed from I fortnight of January. The occurrence of bark eating caterpillar was
observed throughout the year in both varieties.
... Though jamun has various medicinal properties it is being infested by as many as 78 number of insects which includes Lepidoptera (34 species), Hemiptera (26 species), Coleoptera (8 species), Thysanoptera (6 species) and Diptera (5 species) (Rajeshkumar et al., 2010).) Seed weevils like Curculio c-album Fabricius, Apotomorrhinus cribratus (Sch.) and Sitophilus rugicollis Casey infest jamun fruits between May to August months (Talwar, 2014). ...
Fixed plot survey was carried out at fortnightly intervals from March to July, 2021 and 2022 jamun fruiting season at six locations of Belagavi district of Karnataka, India. Survey locations comprised in the study were fruit orchard of KRC College of Horticulture Arabhavi, Dupadal, Ankalagi, Kolavi, Kaitanal and Hidkal Dam with six available varieties viz., Dupadal, Kolavi local, Kaitanal local and Hidkal Dam local, Konkan Bahadoli and AJG-85. Pooled data of 2021 and 2022 for fruit damage due to fruit and seed weevil, Curculio c-album revealed that pest incidence starts with an onset of fruit formation and continues till harvesting of fruits. The overall mean fruit damage percentage ranged from 12.3–41.5% with peak incidence during second fortnight of June. Across all the locations highest (50.1%) fruit damage was noticed in Dupadal variety at Dupadal and at the same time less (19.0%) fruit infestation was observed in AJG-85 at Arabhavi. The overall mean of jamun fruit damage due to Conogethes punctiferalis ranged from 0–3.6% with peak incidence during II fortnight of June. Correlation analysis between percentage fruit infestation due to Curculio c-album and Conogethes punctiferalis with prevailing major weather parameters were studied in cv. Konkan Bahadoli. The fruit infestation due to C. c-album and Conogethes punctiferalis was negatively correlated with temperature, positively correlated with relative humidity. C. c-album had positive correlation with
rainfall whereas C. Punctiferalis was negatively correlated with rainfall.
... Even though the acreage under Jamun planting or cultivation is increasing in the last two decades in peninsular India, due to lack of systematic documentation about Jamun, it has remained as an underutilised and less understood indigenous fruit tree of India which is grown wildly and semi-wildly in tropical and subtropical parts of India (Singh et al., 2011) [12] . Insect pest spectrum of Jamun has over a century of history in India (Iyer, 1919) [4] and at present more than 75 species of insect and mite pests have been documented (Rajeshkumar et al., 2010 andNayak, 2017) [10,7] . Among these, only the bark eating caterpillar, seed and fruit borer complex appeared to be of major concern which needed attention to protect the economic value , Kamalajayanthi et al., 2019, and Hiremath et al., 2021 [9,5,3] . ...

... These findings are in conformity with a result of Raut et al. (2019) [11] who reported that, M. scyrodes caused almost 67 per cent infestation with peak level during June (25 th to 26 th SMW). Whereas, M. scyrodes and Meridarchis reprobata were listed as minor Jamun fruit borers (Rajeshkumar et al., 2010) [10] . ...
Fixed plot survey was carried out to know the extent of Jamun fruit damage caused by Meridarchis scyrodes at different locations. Observations were recorded at fortnight intervals from March to July, 2021 and 2022 Jamun fruiting season at five locations of Gokak taluk and one location of Hukkeri taluk in Belagavi district of Karnataka, India. Survey locations comprised in the study were KRCCH Arabhavi, Dupadal, Ankalagi, Kolavi, Kaitanal and Hidkal Dam with six available varieties (Dupadal, Kolavi local, Kaitanal local and Hidkal Dam local, Konkan Bahadoli and AJG-85). Pooled data depicted the peak incidence of M. scyrodes during II fortnight of June. Highest (58.25%) pest infestation was observed during I fortnight of July in Hidkal Dam local variety, at the same time less (12.50%) pest infestation on fruit was observed in Dupadal variety at Dupadal. Correlation analysis between mean values of per cent fruit infestation due to M. scyrodes with prevailing major weather parameters during fruiting season of 2021 and 2022 were studied in cv. Konkan Bahadoli. The fruit infestation due to M. scyrodes was negatively correlated with temperature, positively correlated with relative humidity in both the years and M. scyrodes had positive and negative correlation with rainfall during 2021 and 2022, respectively.
... The seed is used in Ayurveda, Unani and Chinese medication for stomach related afflictions. So for 78 insect species from five orders viz., Hemiptera (26 spp.), Coleoptera (8 spp.), Diptera (5 spp.), Lepidoptera (34 spp.), Thysanoptera (6 spp.) are known from jamun (Rajeshkumar et al., 2010) and four mite species (Nayak, 2017) of which seed weevil Curculio c-album F., causing significant economic damage to seeds is important (Hiremath et al., 2021). Fletcher (1917) was in a dilemma for placing C. c-album as a jamun pest as it was feeding on seeds thinking seed has no economic value. ...
Among seven insecticides evaluated azadirachtin 10000 ppm (1 ml/ l) was found to be the most effective against seed weevil Curculio c-album F., followed by deltamethrin 2.8EC (1.0 ml/ l) and malathion 50EC (2.0 ml/l). The least effective was spinosad 45SC (0.3 ml/ l) followed by cyantraniliprole 10.26OD (1.8 ml/ l). Three rounds of sprays (new flush, pre bloom and post bloom) of insecticides gave better protection when compared to single/ two sprays. Maximum healthy fruit yield (49.81 kg/ tree) was obtained with azadirachtin.

The survey of insects associated with Jamun in India was conducted and approximately 300 specimens belonging to five orders were collected, which comprises of 78 species mainly representing two orders 1.2., Lepidoptera (34 species) and Hemiptera (26 species) (Kumar et al., 2010). ...
... On S. cumini, two sap sucking pests, whitefly and a mealybug were reported in the present investigation (Table 2). But, in a study as many as 78 species of insect pests on S. cumini mainly belonging to Lepidoptera and Hemiptera orders were recorded [7] . The higher number of insect pest recorded by them can be because of the fact that, survey by them was carried out in forest areas not restricting to forest nurseries as it was in the present study. ...
The observations on the occurrence of forest nursery pests at College of Forestry Nursery, Ponnampet from August 2019 to April 2020 indicated that, Garcinia gummi-gutta, G. indica and Syzygium cumini were majorly infested with pink scales, whiteflies and mealybugs. Chysomelid beetle, Podontia congregata, and a leaf miner; P. congegrata, Busoniomimus manjunathi; Aphids and cow bugs were the insects observed at low level on G. gummi-gutta, G. indica and Albizzia lebbeck, respectively. Sapindus emarginatus recorded the occurrence of a Myllocerous weevil at a lower (0.50 to 6.50) percentage. The incidence of major insects on G. gummi-gutta, G. indica and S. cumini showed a positive correlation with temperature and negative correlation with RH and Rainfall; with significant and non-significant differences.
... Jamun, Syzygium cumini L. (Myrtaceae) is a common evergreen tree in Indian subcontinent with its dense foliage generally grown in tropical and subtropical zones from Myanmar to Afghanistan (Rajesh et al., 2010). The cultivation of this crop in India is increasing owing to its commercial potential. ...
An attempt was made to understand the colour preference vis-à-vis spectral sensitivity of phytophagous eulophid seed borer, Anelmella kerrichi (Narayanan et al.) of Jamun, Syzygium cumini L. using sticky traps. Sex biased colour preferences were observed among the female and male wasps. The female and male wasps colour preference was in the order of blue>yellow>purple>pink>white; and yellow>purple>blue>white>pink respectively. Both the sexes did not get attracted to the green colour. The possibility of standardizing the sticky color traps for the management of A. kerrichi is discussed.
