Key lime trees (Citrus aurantifolia Swingle) are also called Mexican or West Indian lime trees. This species includes a lower yield than lime trees that are normal and creates smaller, lighter-coloured fruit. The trees are also little and rarely grow taller than 12-feet, making them perfect for home gardeners. Key-lime trees are targeted by few pests . However, key-lime trees are susceptible to the same pests as citrus trees.
Citrus Snow Scale
Citrus snow scale (Unaspis citri) especially assaults keylime trees. This scale insect is a type of aphid also called snow scale snow scale louse, louse scale that is white and chionaspis. Although not currently existing in California, itâs on Californiaâs invasive species checklist, and there’s a reasonable threat this pest could come to the state. Citrus snow scales are 1.5 to 2.25 mm long and mostly cause injury to the trunk and large branches. However, itâs also on the fresh fruit, leaves and twigs. Introducing helpful parasitic wasps like Aphytis lingnanensis and manage outbreaks are helped by Encarsia species.
Citrus Leaf Miner
By tunneling involving the upper and the lower surfaces of the leaf citrus leafminer, Phyllocnistis citrella, damages the leaves of trees. In the larval phase of this moth, it assaults all types of trees and are available as far north as the San Joaquin Valley. Citrus leafminers target seldom cause damage on yard key-lime trees to cause significant hurt and tender leaves. Pesticides donât manage the citrus leaf miner. Instead, established pheromone traps or launch parasitic wasps (Cirrospilus and Pnigalio species).
Coccus psuedomagnoliarum, citricola scale bugs, signify a significant issue for trees in the San Joaquin Valley. A significant citricola scale infestation decreases produce the subsequent year and considerably decreases the dimension of fresh fruit. These pests then exude a substance called honeydew and suck sap in the tree. Honeydew attracts sooty mould, which compromises the quality of key-lime fresh fruit. Broad-spectrum pesticides, including organically accepted petroleum oil sprays you may get in a nursery, get a grip on citricola scale better than controls. Inland, avoid implementing petroleum oil sprays in temperatures above 9 5 levels Fahrenheit or if relative humidity falls to 20-percent or under. In the event that you reside in a coastal location, a void applying petroleum oil sprays in the event the temperature is greater than 85 levels Fahrenheit or the relative humidity is below 30-percent.
Citrus Fruit Tree Leaf Roller
The citrus fruit tree leaf roller (Archips argyrospila) is a green caterpillar. These pests are called leafrollers by wrapping blossoms or leaves as well as silken threads, due to the fact that they type nests. They prey on new development, which offers entry websites for harmful organisms when the larvae arise from your nests. If perhaps not handled, the good fresh fruit drops the key-lime tree within one to to 2 months off. To to manage this pest, re lease the wasp species Trichogramma or spray with Bacillus thuringiensis, which is is appropriate for use in-organic orchards.
