Guava is scientifically Psidium guajava and belongs to the family Myrtaceae. Guava trees are damaged by the citrus flat mite. Guava is an evergreen shrub or small tree grown for its edible fruits. Guava has a slender trunk with smooth green...

Email Litchi is harmed to an impressive degree by the bark-eating caterpillars, which assault trees, everything being equal, especially the more established ones, bringing down their essentialness. They bore into the trunk, principal stems, and thick parts of litchi trees. They have a wide scope of host plants including litchi. Where did the old plants go? The old, obscure, and ignored plantations are more inclined to go after this pest. Whenever seriously pervaded, the whole branch or tree might kick the bucket. The female lays eggs in a different form of cuts and cleft in the bark in bunch toward the beginning of June. The egg usually hatches in 8 to 10 days and recently arose caterpillars emerge. The recently arisen caterpillars begin snacking at the bark. The assault by this irritation is described by the presence of long-twisting, thick, blackish, or caramel strip-like masses made out of little chips of wood and excreta, the two of which intermix with the assistance of sticky material discharged by the caterpillar. Following 2-3 days, hatchlings bore into the storage compartment or principal branches for the most part at the forking spot and make burrow downwards. There is just a single hatchling in each opening, and there might be 2-16 openings in each tree, contingent on the force of pervasion and age of the tree. By ceaselessly eating up the tissues, it burrows through the stem and branches. The caterpillars stay inside the drilled openings during the day and emerg...

Bark eating Caterpillar – Scientific Name > Indarbela tetraonis What is Bark eating Caterpillar? As the name suggest it is a caterpillar which lives and feeds on the branches and stem of the plants. Like, every caterpillar it is a one stage of Inderbela moth which hampers the economics in Agriculture. Egg– The moths lay light brown spherical eggs in clusters in the cracks and crevices of the bark. After 7 to 11 days the eggs hatch into small neonate. Larvae– The larvae moves out in search of food in the concealed places of shoots and bore a tunnel downward in to the wood. The tunnel is used as shelter during the day hours. While at night, the larvae come out and start feeding on the outer bark. This period last for another 27-298 days. Pupa– This is a rest phase of it for growing itself in adult. The phase is conducted in the hole/tunnels made by them during its larval stage, while within 20-25 days of pupation it becomes an adult. Adult– The male adults are smaller than female ones and also have shorter life span. This phase varies from 4-7 days. How does it damage the plant? The most damaging stage of the insect is larval stage. The larvae bore holes in search of food in the stem and branches which ruptures the tissue of the plant blocking the passage of food and water in the plant, which may be fatal for plant. Symptoms • Irregular tunnels and patches covered with silken web consisting of excreta and chewed up wood particles on the shoots, branches, stem and main trunk ...

After some searching, I think I have found a possible answer to the bark damage you are seeing on the Loquat. This is not a canker. The symptoms are not consistent with the localized lesions resulting from death of the cambium that defines a canker type disease. There is a bark eating caterpillar, Indarbela quadrinotata, that causes exactly the type of damage evident in the images. This insect appeasr to be common in Southeast Asia, and other parts of the world on Loquat and there is a quite a bit of information on the internet on how to deal with it. I would urge you to stop peeling the bark, and let it come off naturally. I am unfamiliar with pesticides and the details of the availability of the proper chemicals that might control the problem in Australia. I suggest you contact a local expert for this sort of advice. However, I did read of some instances where trees were experiencing this problem butthey appeared to tolerate it and bear fruit normally. The extent of the problem appears to be very great on the tree, yet the crown lookshealty, as you mention. You might cut through the bark in a small area and see if the problem is superficial or extends down into the cambial layer. If the cambium is still green, then perhaps the problem is cosmetic and will not permanently damage the tree. If the area where you cut is brown, and discolored, then control is probably warranted.

We’ve got a Loquat tree that’s probably about 12 years old now, and maybe 10 feet tall. It has produced varying quantities of fruit the past few years. Some fruit is emerging this year, but probably not as much as we had 2-3 years ago. This disease or whatever it is has been apparent for a few years now. It started as a single ring circling around one of the lower limbs. Wonder if you have any idea what’s causing it and if we should be doing something to deal with the matter. Thanks much, Jerry B. I am thrilled to hear about your Loquat ( Eriobotrya japonica e-ri-o-BOT-ri-ah ja-PON-i-ca) and the fact that you have had it growing for over ten years. I was first introduced to this wonderful small ornamental tree back in the 1970's when we were trying to find new plants to use in residential gardens. Most of the time was spent in trying to get them to survive our winters back then so that we never really saw its full potential in the landscape. When I moved to Natchez, MS right out of college many gardens utilized this small tree and it made quite an impact with its tropical looking foliage and small orange fruits. It is wonderful to hear that Loquat can find a home here in north Alabama and be one of the choices we have in selecting small ornamental trees. Loquat is a native of China that was introduced to the Mid-East region and then into Europe and finally the United States in the late 1800’s. It is a small tree growing fifteen to twenty feet tall with an equal spread and ...

An experiment on the biology of guava bark eating caterpillar (Indarbela tetraonis Moore) was conducted during 2012-13 at College of Horticulture, Bidar. Eggs were 0.67 to 0.73 mm long and 0.42 to 0.46 mm wide and they hatched in 7 to 11 days. Full grown larvae were 37 to 43 mm long and 6 to 8 mm wide. Larval duration was 274 to 298 days. Pupae were 11 to 15 mm long and 4 to 6 mm wide and the pupal period was 21 to 26 days. Male adult had wing span of 11 to 13 mm length and width of 20 to 24 mm. Female adult had wing span of 12 to 14 mm and width of 25 to 27 mm, Chlorantraniliprole 18.5 SC registered 100 percent control of the pest and highest yield of 24.85 t/ha and 25.00 t/ha during 2013 and 2014, respectively • Anonymous.
