I dont think its this particular beatle if the culprit is a beetle anyway. I think stat the branches are falling off on their own, see on the pic with the stump and the new flush, the leaves are heavy on those new unsturdy branches and they are probably falling off on their own when theres wind, and rain that accunulates and makes them heavier. When a tree is cut back hard like this the new flushes often have a weak connection to the main trunk, ive seen this on many occasions and species. The flushes usually need more tipe to fatten up at the base and get stronger, until this time comes, some of them will be bracking and falling off.
Was your pommegranite also topped and were the branches that were bracking also new growths?

The mango had been suffering from twig drops several times a week even before it was pruned back and it was always the new flushes. Dropping occurs regardless of weather. The pomegranate hasn't been topped recently and the breakages seem to come at random points and not on the nodes. Fortunately it seems to have stopped with the pomegranate.

Based on what I found Googling, the family of beetle this belongs to have some notorious species known for boring into wood although the damage pattern in this case seems to not add up. Shouldn't there be holes instead of cuts?

I recently had my mango tree trimmed off to its largest branches which effectively defoliated it. It had been suffering from various diseases and insect infestations in its foliage which rendered it completely unproductive. Now that leaf flushes have started to come back, some nasty critter is once again starting to trim off twigs. I have found a beetle quite a while back. Could this be the culprit? (see picture below)

By the way, during the time when the mango was leafless, my nearby pomegranate shrub had a few of its branches trimmed off. Is it possible that it may also have been responsible for that?

Tropical Fruit Discussion / Re: My first mabolo
« on: August 23, 2022, 01:46:25 AM »
Finally, I've found someone again from the PI who's still active in this forum. I once saw a seedless mabolo marked for sale a few years ago on a fruit stand. I didn't buy it as I really haven't had a good impression on the fruit due to its unusual complex pungency and mealy texture but then those are of the typical red fuzzy seeded kind. It seems you have to eat it at a young enough age in order to acquire the taste for it. That however looked different, as it was a light peach colour with little fuzz. It also didn't have a strong smell, at least from what I remember. Maybe it did, maybe not. Based on the circulating resources in the Internet, some preferred varieties have been developed but it's not well-known. That thing I saw could be one of them.

Tropical Fruit Discussion / Re: What afflicted the sugar apple?

Any suggestions on how to treat such infestations? It's good that it hasn't reached Florida soils yet. It really brings down the plant's productivity.

Some of my fruits have been ruined with these coverings that has the texture of an ant mound which is also very hard to remove since it is binded by a white sticky fibrous "substance", whatever that may be. Is this caused by some kind of borer? Is the remainder of the fruit good to eat?

I have planted seeds from a large marang fruit with mild odour. One seed in particular looks like it had sprouted several shoots although it is growing at a slower pace compared to seeds that produced only one as shown in one of the pictures below. Is this polyembryony? And if so, is this quite common among Marangs and Artocarpus species in general? Can this also be a possible source of clones like those in polyembryonic mangoes?

Why has that section been flooded with lots of advertisements lately? Has it not been maintained? Calling the attention of admins and moderators

Your preference has finally switched.

I've been told there is great Salak. My friend brought me some seeds and two made the journey. Most were taken from her. From what I can tell it is different than my three varieties.
Contrary to some reports indicating the abundance of salak in the Philippines, that fruit is nowhere to be found here. It's unheard of although rattan fruits which bear some resemblance to it is quite ubiquitous.

Ah! So JonM what fruit seeds would you suggest?
As Mugenia has said, many fruits found here are found in many parts of the world. Adding to the relatively common fruits previously mentioned that I recommend are jackfuits, chicos, marangs, mangosteen, star apple(currently in season), bignay, duhat or java plum, starfruit, kamias, tamarind, guava, and macopa or Java apple and its close relatives, pili nuts, and sugar apples. Avocados are common but it's a lottery when it comes to quality. Aratiles is so common it's left to birds.
Lesser known species of fruits that are often only well known in some localities are acerola, Rollinia, mabolo or velvet apple(Diospyros blancoi), lipote(Syzygium curranii), chempedak(only in Palawan), gumihan or pedelai(Bicol Region), hagis(Syzygium sp. - can't find species name), camachile (Pithecellobium dulce), cashew, berba(Lemon drop mangosteen), binucao (Garcinia binucao? - don't know if sp. name is valid), pahutan(Mangifera altissima, Luzon), huani(Mangifera odorata, Mindanao), galo(Anacolosa fructescens), tabu(Willughbeia elmeri? - not universally recognized sp. name, Palawan), palau saguit-saguit(Willughbeia sarawakensis, Palawan), and Paratungon(Salak relative but sour and used in wine-making instead. Palawan), and the gymnosperm "bago"(Gnetum gnemon). I forgot some species but most of them are even rarer.


Very good list !
Thank you very much.
And oh, this article should add more fruits to the list though the area where the study was conducted is in the Cordilleras.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4025321/#!po=21.9101

Ok, you are both right. Salak is not found naturally in most of the Philippines but S. ramosiana is found in Palawan.  The flora of Palawan more closely resembles that of Borneo than that of the rest of the Philippines.  Reports are sketchy but it sounds like it is a species worth looking at further for its fruit.  I looked into a trip to Palawan earlier but it sounds like getting seeds out legally might be "complicated".

John
S. ramosiana is called "Paratungon". Quite sour though, like rattan

Tropical Fruit Discussion / What are these spots on my pomegranate?
« on: January 15, 2018, 12:13:30 AM »
What are these spots on the leaves of my pomegranate? Is this a bacterial or fungal infection? I have sprayed Phytosan ADBAC on my plants and pruned it severely yet these spots keep coming back. Older leaves are more affected and these often fall off. New leaves also get distorted shapes. What can be done? I know my place does not have the ideal climate so that may be a factor.

Tropical Fruit Discussion / Large Earthquake Struck Costa Rica

A magnitude 6.5 earthquake has just struck Costa Rica. It seems the region has gotten multiple big shakes in a relatively short period of time. We hope our fellow forum members affected are unscathed. Stay safe!

Tropical Fruit Discussion / Re: Deformed New Leaves on Young Jabuticaba
« on: November 10, 2017, 08:33:46 AM »
Yes, it looks like some of my supposed sabaras or coronatas. Leaves are not red because is is not so much cold in your area!
I find classifying Jabuticabas to be quite confusing.
hi!

Probably excess phosphorus in the substrate, but do not worry, do not kill the plant, you can leave the seedling in the shade to acclimate better, leaving only a few hours of sun a day.

Yesterday I did fertilization with phosphorus in my jabuticabas and some may soon have leaves as well.

Another rarer cause here is mite attack, but it also does not cause much damage to the plant.

Good farming!
I have removed the beads of fertilizer that have not dissolved into the soil and I leached excess fertilizer in the soil with water in the pot. Thanks for the information.

Hi JonM, is that species myrciaria coronata or another thing?
From what I remember it was labeled the common Myrciaria cauliflora. This is a seedling I bought from the late local fruit guru Prof. Coronel's collection. It seems to me there is only one species of Jabuticaba in the country, or is it just me. What I just noticed in the plant is that new leaves are not an intense red or salmon color like what I saw in other Jabuticabas in this forum. New leaves are green, with only a little bit of salmon color that quickly disappears.

These are worth growing and probably not common in the Philippines.
Atemoya, loquat, achacha, Mexican Garcinia, Psidium Guineense, Barbados cherry, canistel, ross sapote, figs, apples, persimmon, jujube, passion fruit, white sapote, guabiju, wampee, pitangatuba, marula, monkey orange, mulberries, peaches, citrus, kwai muk, avocado, akee, black sapote, mamey sapote, grumachama, icecream bean, pomegranate, cambuca, mamoncillo

There are so many good fruits common or native to the Philippines like duhat, velvet apple, camachili, chico, sineguelas...

Interstingly, fruits like the canistel, mamey sapote, mulberries, rollinia, passion fruit, atemoya, acerola, black sapote, pomegranate etc. have been in the country for a long time. Many people even mistake those aforementioned fruits as indigenous species. It just seems they never took off because people don't know how to use it. Avocados and are an exception and is actually quite common. Widespread citrus plantations on the other hand were destroyed in the 60's by citrus canker. I'm not sure if peaches, persimmon and Mediterranean figs can be grown in Baguio though. It may be worth a try, I just think its either too wet and humid or too warm in winter months.
In addition, Campomanesias, and other species of Mangifera and Durio may work in the highland subtropical climate of Baguio.

21
Cherry of the Rio Grande, Green Sapote, Tamarillo, Naranjilla, Mountain Papaya, Macadamia, Cherimoya, Lucuma, Raspberries(We have a native species)
For additional information, Baguio City has a few nights where temperatures drop to around 7°C (45°F) every year. On the other side of the scale, temperatures rarely rise above 27°C (80°F). The city also has a dry season from December-April. I hope that helps.

Tropical Fruit Discussion / Deformed New Leaves on Young Jabuticaba
« on: November 07, 2017, 02:22:16 AM »
Hello, this is my first post in this board. I have a Jabuticaba which is around a year old. Recently, it has stopped making new flushes of leaves for a relatively long period of time after putting out new growth at a regular pace. I therefore put a few beads of complete fertilizer to the soil around the plant. It later made an extensive flush of new but deformed leaves, though not all leaves exhibited that characteristic. A few deformed ones even turned brown and fell off. Does the Jabuticaba need a period of dormancy even in a fully tropical climate? What should I do?

Tropical Fruit Discussion / Re: Introduce Yourself
« on: November 07, 2017, 12:55:24 AM »
Hello everybody, you can call me Jon. I am an undergraduate student in University of the Philippines Los Baños, an institution known for agriculture and forestry. I have had interest in growing plants since I was seven although it was mostly ornamental plants. My fascination with tropical fruit was kindled much more recently when I realized that there is such a huge diversity of edible fruits out there, most of which are underutilized due to the stigma placed upon lesser known plants as second class food. My discovery of this forum around a year ago just strengthened my interest in tropical fruits and I have been regularly following this forum since although it is only now that I have created an account. I am looking forward to interact with this community. :)
