Dragonfli Horse Chestnut Leaf Miner Pheromone Trap - Includes 3 Lures - Catch, Kill & Monitor Insect Pest Numbers

Product Information

The eggs of this type of leaf miner are translucent. The mature females use their tubular reproductive organ to slice slits into plant twigs to lay their eggs but can also place her clutches inside of leaves. Understanding the lifecycle of leaf miners is essential to controlling them. It all starts when mature larvae overwinter in the soil under the plants. Then, as the spring temperatures warm up the ground, the larvae mature to their pupal stage. By late April, they’re young adults. Healthy plants are the least damaged by these little chewing pests, so ensure your plants are well taken care of. Regularly fertilize your plants, keep them pruned well, and provide compost or other good soil for them to grow in. Plant health is paramount! The most important part of leaf miner treatment is not knowing how to get rid of leafminers, but prevention. There are a few different options for preventing the assortment of flies and moths that produce leaf miners from causing future harm.

Adult leaf miners don’t damage plants or their foliage. The leaf miners live up to two weeks, during which time they will mate, and the female will again lay eggs in foliage. The leaf miner egg deposits resemble tiny raised blotches or spots on the leaf, at this stage in their life cycle. Leaf miner eggs hatch in only 10 days. Implementation of microbial control products, such as Antario from Russell IPM has shown success in Tuta control. The naturally occurring soil bacterium, Bacillus thuringiensis var. kurstaki has exhibited a satisfactory efficacy against Tuta absoluta larval infestations. Delayed application of Bacillus thuringiensis may cause higher insect mortality as the insects become more susceptible to the pathogen after a longer period of feeding on the resistant crop. It is reported that in a combined application of mass release of Trichogramma pertiosum and Bacillus thuringiensis resulted fruit damage only 2 % in South America. Each trap comes with three pheromone lures, each of which last up to 6 weeks, giving the trap an initial 18-week protection. The pheromone lures should be replaced 2 to 3 times between April and August to catch as many hatching generations as possible.Various types of insects produce larvae that “mine” leaves. There are thousands of insect species considered to be leaf miners. Common types of leaf miners include spinach leaf miners ( Pegomya hyoscyami), vegetable leaf miners ( Liriomyza sativae), and citrus leaf miners ( Phyllocnistis citrella). Leaf Miner Life Cycle Careful inspection should reveal clutches of the small eggs on the leaves. Anytime you spot a leaf miner tunnel on a plant, crush the lines between your fingers to kill the larvae but do little to no further damage to the leaf. Leaf Miner Traps Adult females lay about a total of ~ 250 eggs during their lifetime. Eggs are small cylindrical, creamy white to yellow and ~0.35 mm long. Tuta absoluta will deposit its eggs on the underside of leaves or stems. Hatching takes place after 4-6 days. Experience from Europe indicates that once established, the moth will cause severe damage to the foliage of horse chestnut on an annual basis, and defoliation before normal leaf-fall in the autumn. The larvae mine within the leaves and at high population densities they can destroy most of the leaf tissues. Damage can be reduced by removing fallen leaves during the autumn and winter and either composting them thoroughly, to destroy the over-wintering pupae, or if the leaves are collected into smaller heaps, by covering them with a layer of soil or other plant material to prevent adult emergence in the following spring.” end quote

The egg parasitoid Trichogramma achaeae has been identified as a candidate for biological control of the South American Tomato Pinworm, Tuta absoluta. On greenhouse conditions a high efficacy, 91.74 % of damage reduction was obtained when releasing 30 adults/ plant (75 adults/ m2) every 3-4 days on August and September of 2008 in the southeast of Spain (Cabello et al., 2009).It’s fairly easy to identify the damage caused by a leaf miner infestation because these pests feed on parts of the plants with tissue containing the lowest levels of cellulose and tannins. Leafminer species don’t limit their feeding to edible plants. Oak and aspen leaves are subject to leafminer problems, and leaf miner boxwood issues are common in hedging. A number of flowering plants, trees, and shrubs are susceptible to damage as well by the vegetable leaf miner, citrus leafminer, and American serpentine leaf miner. Pour baby shampoo into a spray bottle and add one drop each of peppermint, tea tree, and cinnamon oil to the soap. Swirl the bottle gently to mix and spray the solution around the bee infested area.

These destructive insects tend to mine onto the lower leaves of a plant because their tissues are composed of tannins and cellulose. The leaf miners are the larvae (or maggot) stage of this insect variety that are found on either side of the surface of plant, bush, and tree leaves. The serpentine mine tunnels are long, thin, and winding – like the body of a snake. There are typically ample bends in the serpentine mine tunnels and the lines run in a single direction, like a section of road.The egg stage lasts ten days or less. In warm weather, the leafminer eggs hatch into larvae. When the larvae hatch they are at their most destructive because they tunnel through the leaf tissue. As the larvae feed, they leave squiggly trails or lines on leaves that leaf miners are associated with. This feeding phase lasts for 2-3 weeks depending on the particular species. Once the larvae near pupation, they chew through the skin of the leaf and drop onto the ground below. Then they burrow an inch or two beneath its surface. The leaf miner then burrows to the edge of the leaf, causing it to curl up. The leaf miner larvae goes into the pupal stage, where it takes between one and three weeks to develop into a leaf miner insect. There is also scientific evidence supporting the use of Spinosad for natural leaf miner control. A 2018 study found that using Spinosad helped to kill off tomato leaf miners in greenhouses. The natural solution was most effective when used along with other leaf miner eradication and control methods.
