Combating Spotted Lanternfly with AcuSpray’s Drone Technology

The peaceful and productive orchards and vineyards of the northeastern United States have recently come under threat from an unwelcome visitor: the Spotted Lanternfly (SLF). This invasive planthopper, which originates from parts of Asia, first made its presence known in Pennsylvania in 2014. Since then, its rapid spread has become a cause of concern for agronomists and farmers alike.

The areas currently affected extend beyond Pennsylvania, engulfing regions of New Jersey, New York, Maryland, Delaware, and Virginia. 2022 saw the discovery of a breeding population in Oakland County, Michigan, with smaller populations detected in neighboring states of Ohio and Indiana. The rate at which the SLF has been able to establish itself in new territories is alarming, to say the least.

For industries that rely heavily on crops such as grapevines, maples, and hops, the SLF isn’t just an ecological menace but a significant economic one. The Michigan grape industry, for example, faces a potential calamity if SLF populations are not controlled. These insects feed by sucking sap from plants, causing them considerable stress and injury. While the economic damage to tree fruits like apples and peaches has been minimal so far, vineyards have been reporting significant harm.

Moreover, the SLF is not just an adversary to commercial enterprises. Residential landscapes, especially in areas with high SLF populations, face the annoyance of these pests, turning serene backyards into bustling insect hubs.

In understanding the gravity of this issue, it’s essential to recognize both the immediate risks posed by the SLF and the potential long-term implications for ecosystems and economies. While the aim should not be to induce panic, awareness and proactive measures are crucial in this fight against the Spotted Lanternfly invasion.

Identifying the Enemy: Lifecycle and Characteristics of the Spotted Lanternfly

To effectively combat the Spotted Lanternfly (SLF) menace, it’s crucial to understand its life cycle and be able to identify the insect in its various stages. Each stage comes with its unique set of characteristics, making it imperative for individuals and professionals to be well-acquainted with them. This aids in early detection and effective control.

1. Eggs:

  • Appearance: The life cycle of the SLF begins with its eggs, which overwinter and can tolerate harsh cold conditions, such as Michigan winters. These eggs, usually laid in September, appear as grey/brown splotches that can be easily mistaken for lichen or tree bark due to their camouflaged nature.
  • Location: While they can be found on various surfaces, it’s not uncommon to see these egg masses on tree trunks or other hard surfaces.

2. Nymphs:

  • Early Stage: Emerging in early May from the overwintered eggs, the nymphs initially appear as small black creatures with distinctive white spots. Their appearance can sometimes be mistaken for small spiders.
  • Growth: As they mature, the nymphs undergo four nymphal instars. The final instar (pictured below) turns a vibrant red with white spots and black stripes. By this stage, they grow to the size of a dime.
  • Behavior: Nymphs, like adults, exhibit strong jumping abilities. Their movement is mainly characterized by walking, but they will quickly jump when prodded or disturbed.

3. Adults:

  • Appearance: Emerging in late July, adult SLFs are strikingly noticeable. They are roughly an inch long, with black bodies and light grey wings dotted with black spots. Beneath these wings, their hind wings boast vivid patterns of red, black, and white. When these are exposed, the SLF bears a resemblance to a colorful moth.
  • Behavior: Unlike many insects, adult SLFs are more walkers than flyers. They tend to keep their wings folded behind them when resting. Just like the nymphs, they possess long legs, making them strong jumpers. An interesting behavior to note is their tendency to hide when they sense an approaching threat.

Understanding these stages aids in the identification and tracking of SLF populations. Moreover, knowledge of their behavioral patterns, especially their preference for walking over flying and their habit of jumping when disturbed, can assist in effective monitoring and control strategies.

The Impact of Spotted Lanternfly on Plants

As beautiful and exotic as the Spotted Lanternfly (SLF) might appear, its feeding habits spell trouble for a variety of plants, with some industries, notably grapevine growers, standing at the forefront of potential economic damage.

1. Feeding Mechanism:

  • How They Feed: SLFs belong to the planthopper family, a group within the Hemipteran order, which also includes insects like stink bugs and aphids. These creatures possess specialized piercing-sucking mouthparts, enabling them to extract sap directly from plant parts such as trunks, branches, and leaves.
  • Impact: They do not feed on fruits directly. Instead, their feeding method can induce or worsen plant stress, manifested through symptoms like wilting, leaf yellowing, and premature leaf drop.

2. The Grapevine Worry:

  • Immediate Threat: Grapevines are particularly vulnerable to SLF infestations. Excessive feeding by these insects can drain grapevines of essential carbohydrates, affecting the plant’s overall health and reducing its winter hardiness. Such an impact can result in a marked reduction in grape yield.
  • An Observational Note: Despite the observed SLF feeding on tree fruits like peaches and apples in some regions, no significant economic damage has been reported in fruit tree orchards, a silver lining for orchard owners.

3. The Honeydew Menace:

  • What is Honeydew? As SLFs feed on the sugar-rich sap of plants, they excrete a sugary substance known as ‘honeydew.’ This substance is similar to the waste produced by aphids and scale insects.
  • Volume Matters: Given their size, SLFs produce honeydew in much larger quantities than smaller pests like aphids. This can lead to a significant accumulation of the sticky residue around the feeding sites.
  • Secondary Issues: The honeydew not only makes surfaces sticky but also promotes the growth of a dark, unsightly fungus called ‘sooty mold.’ While the mold doesn’t harm plants directly, it can block sunlight from reaching plant surfaces, affecting photosynthesis. Moreover, large amounts of honeydew in orchards can be bothersome for harvesters, possibly leading to further economic implications.

In essence, while the Spotted Lanternfly might not be a direct threat to fruit, its feeding habits and subsequent excretions pose challenges that cannot be overlooked, especially for grape growers and other affected industries. Awareness of their feeding patterns and understanding the potential risks is the first step toward formulating effective strategies to combat this invasive pest.

Monitoring Techniques for Spotted Lanternfly (SLF)

In the fight against the invasion of the Spotted Lanternfly, early detection and prompt action are vital. With this invasive pest rapidly making its mark across regions, it’s imperative for farmers, growers, and residents to be equipped with the right monitoring tools and techniques. Here’s a closer look at some of the most effective monitoring practices currently in use.

1. Visual Scouting: The First Line of Defense

  • What it Entails: Visual scouting involves actively searching for the different life stages of SLF – from eggs to adults – on plants, trees, and other surfaces.
  • Optimal Time: Late spring, particularly in early May, is an ideal time to start visual scouting as this is when the eggs hatch and nymphs start to appear.
  • Lookout Points: While SLF can be found on various plants, they have shown a marked preference for tree-of-heaven, grapevines, and certain trees like maples and black walnut.

2. Circle Traps: Passive yet Effective

  • The Design: Circle traps consist of a funnel-like mechanism installed on tree trunks. As SLFs move upwards on trees, they get funneled into the trap, preventing their escape.
  • Why it Works: SLF, both nymphs and adults, tend to move upwards on tree trunks, making circle traps an efficient way to capture them. The funnel design ensures they remain trapped.
  • Placement is Key: For maximum effectiveness, circle traps should be placed on SLF’s preferred host trees.

3. Winter Monitoring: The Egg Mass Challenge

  • Egg Mass Characteristics: During winter, SLFs lay their eggs, resulting in grey/brown splotches that may often be mistaken for lichen or resemble the tree bark itself. This makes them harder to detect.
  • Monitoring Importance: Despite the challenge, scouting for egg masses in winter is crucial. Each egg mass contains numerous eggs, and detecting and destroying them can significantly reduce the next season’s population.

4. Targeted Monitoring for High-Risk Areas

  • Industrial Shipments: Given the belief that SLF might have initially arrived in certain regions via industrial shipments, monitoring such areas is essential.
  • High Traffic Zones: Places like wineries, U-pick orchards, and other agritourism sites might inadvertently contribute to the pest’s spread due to human movement. Regular checks in such areas can help in early detection.

In summary, regular and systematic monitoring is the cornerstone of managing the SLF invasion. By combining both active and passive monitoring techniques, regions affected or at risk can put up a formidable defense against this invasive pest, safeguarding their agricultural and horticultural interests.

Old School, Yet Still Effective: Traditional Management Techniques for Spotted Lanternfly (SLF)

As the battle against the Spotted Lanternfly intensifies, several traditional techniques remain a staple in our arsenal. Though technological advancements have brought forth innovative solutions, these conventional methods still play a pivotal role in curbing the spread and impact of this invasive pest.

1. The Power of the Human Hand: Squishing and Scraping

  • Squishing Adults: Though it might sound rudimentary, manually squishing adult SLFs can be effective, especially in areas of minor infestation. This method is eco-friendly and requires no special equipment.
  • Scraping Off Egg Masses: Detecting and scraping off SLF egg masses from trees, stones, equipment, and other surfaces helps reduce the next generation’s population. A simple plastic card or knife can be used to dislodge the egg masses, which can then be placed in a bag with rubbing alcohol or hand sanitizer to ensure they are neutralized.

2. Chemical Warfare: Pesticides and Their Challenges

  • Chemical controls, including insecticides, can be effective against SLF, especially during severe infestations. They act fast and can cover larger areas.
  • Environmental Impact: However, there’s always a concern about the environmental footprint of chemical applications, especially on non-target organisms like bees, butterflies, and other beneficial insects.
  • Resistance Development: Over time and with frequent use, SLFs may develop resistance to certain chemicals, rendering them ineffective.
  • Application Nuances: The timing and manner of chemical application, along with the understanding of SLF’s life cycle, are crucial for maximizing efficacy while minimizing environmental impact.

3. Post-Harvest Vigilance: Scouting Orchards and Vineyards

  • Why It’s Important: After the harvest season, there’s often a misconception that pest management can take a backseat. However, post-harvest scouting in orchards and vineyards is vital for detecting egg masses that may have been laid during late summer or early fall.
  • Economic Benefit: Detecting and managing SLF populations post-harvest can prevent potential economic losses in the subsequent year. This is particularly important for grape growers, as SLFs can compromise grape quality, affecting wine production.

In conclusion, while cutting-edge techniques and tools are advancing SLF management, traditional methods remain both relevant and effective. A combination of these techniques, tailored to specific environments and situations, is likely the best approach to mitigate the threat posed by this invasive species.
