How Climate Affects Pest Risks in Gardens

Climate change is reshaping how pests behave, creating challenges for gardeners across the U.S. Warmer temperatures, shifting rainfall patterns, and longer growing seasons are enabling pests to thrive, reproduce faster, and expand into new areas. This means more frequent outbreaks, unfamiliar species, and increased damage to plants.

Key points:

• Warmer winters allow pests to survive and reproduce year-round.
• Changing rainfall creates ideal conditions for pests like mosquitoes and termites, while drought-stressed plants are more vulnerable.
• Pests are migrating northward as temperatures rise, disrupting ecosystems.
• Plant diseases spread faster in humid or wet conditions, compounding the problem.

AI tools, such as pest monitoring systems and predictive models, are helping gardeners tackle these issues by providing real-time alerts, tailored advice, and climate-specific planting strategies. Combining such tools with smart gardening practices - like planting pest-resistant crops and adjusting schedules - can help mitigate these growing risks.

Managing Changing Pest Pressures in a Changing Climate

Climate Factors That Increase Pest Risks

Several climate-related changes are creating ideal conditions for pest outbreaks in American gardens. Recognizing these factors can help gardeners understand why pest problems are becoming more frequent and challenging.

Warmer Winters and Longer Growing Seasons

Historically, cold winters acted as a natural pest control, reducing pest populations. But with milder winters, more pests are surviving through the season. As Sherrie McCleary, a Master Gardener from Franklin County, notes:

"Be aware that insect populations may increase with warmer temperatures and longer growing seasons." ^[4]

Longer growing seasons mean pests have more time to feed and reproduce. When the growing period extends from early spring to late fall, many insects can produce multiple generations in a single year. Warmer temperatures also speed up their development ^[4].

Looking ahead, climate models predict that global temperatures could rise by 3.2–7.2°F (1.8–4°C) by the end of the century, which will likely make these trends even more pronounced ^[1].

Changes in Rainfall Patterns

Shifts in rainfall - periods of intense storms followed by drought - are also affecting pest populations. Heavy rains can push pests out of their natural habitats and into human environments ^[6]. At the same time, excessive moisture creates ideal conditions for pests like mosquitoes, termites, and rodents to thrive ^[5].

Research has shown that increased summer rainfall can lead to a surge in certain pests, like wireworms, which move closer to the soil surface under wet conditions. However, small pests such as aphids, mites, and whiteflies can be washed away during heavy downpours ^[1].

Droughts bring their own problems. Plants under drought stress produce fewer defensive compounds, making them easier targets for insect attacks ^[1]. Considering that over 80% of global crop production relies on rainfall, these changes in precipitation patterns are critical for agriculture ^[1]. Additionally, as pests adapt to these shifting conditions, they may seek out new territories.

Pests Moving to New Areas

The combination of warming temperatures and changing rainfall patterns is breaking down historical pest boundaries. Pests are migrating into regions where they were previously absent, taking advantage of new ecological niches ^[1]. Low temperatures, which once kept certain pests confined to specific areas, are becoming less of a barrier.

For example, pests like the European corn borer and Diamondback moth have expanded their ranges by hundreds of miles. Similarly, studies on European butterflies found that 63% of 35 non-migratory species had shifted their ranges northward by 22 to 149 miles (35 to 240 km), while only 3% shifted southward ^[1].

These shifts are further accelerated by global trade, which helps pests spread to new regions. As pests move into new areas and host plants shift their growing zones, farmers face increasingly complex pest challenges ^[1].

Pests and Diseases Made Worse by Climate Changes

The impact of climate change on pests and diseases is becoming increasingly evident. These threats are growing more aggressive, appearing earlier in the season, and causing unprecedented damage. Below are examples that highlight how shifting climates are intensifying pest pressures and plant disease risks.

Pests That Respond to Climate Changes

Warmer temperatures are speeding up pest activity, reproduction, and migration across the U.S. ^[2].

In California, pests like the codling moth, peach twig borer, and oriental fruit moth are thriving under rising temperatures. Studies reveal these pests are emerging up to 28 days earlier and completing their life cycles faster, with generation intervals shortened by as much as 19 days ^[3].

"These three pests are notorious for infesting most of the walnut, almond and peach orchards of California, causing extensive damages by reducing quality of fruits and nuts."

• Jhalendra Rijal, UC Cooperative Extension integrated pest management advisor and entomologist ^[3]

The Northeast is also seeing milder winters and earlier springs, which extend the activity of ticks and mosquitoes throughout the year ^[7]. Similarly, pests like ants, rodents, and flies are remaining active year-round, leading to more severe infestations ^[7].

Climate change is pushing pests into areas they previously couldn't survive ^[12]. Globally, pests and diseases are responsible for about 40% of crop production losses, with damages from pest invasions exceeding $423 billion in 2019 alone ^[12][13].

The screwworm is an alarming example of how climate barriers are breaking down. Historically, freezing temperatures limited its spread in northern climates. However, as UC Berkeley professor emeritus Gutierrez warns:

"With climate change … if it becomes warm enough, and you can get permanent establishment in those areas, then we got a problem." ^[11]

Plant Diseases Linked to Climate

As pest populations grow, plant diseases are also taking advantage of shifting climate patterns, particularly changes in temperature and moisture. In fact, moisture plays an even bigger role than temperature in driving plant disease outbreaks ^[10].

Fungal and oomycete pathogens thrive in high-moisture environments. Diseases like root rot (Pythium and Phytophthora), Myrtaceae rust (Puccinia psidii), septoria leaf blotch (Zymoseptoria tritici), and bacterial leaf blight (Xanthomonas oryzae pv. oryzae) are all exacerbated by increased humidity ^[9][10].

Many fungal pathogens require at least 4–6 hours of leaf wetness to infect plants ^[10]. With changing rainfall patterns leading to longer periods of plant wetness, these pathogens are finding more opportunities to spread. For instance, Cercospora zeae-maydis relies on high humidity for extensive sporulation, while elevated soil moisture boosts the virulence of Sclerotinia sclerotiorum and Ralstonia solanacearum ^[9][10].

The link between climate change and plant diseases creates a troubling chain reaction. Leigh Greenwood, Director of TNC's Forest Pests and Pathogens programs, explains:

"Climate change often makes trees even more susceptible to damage from insects and disease, which reduces a forest's ability to sequester carbon which, in turn, worsens climate change. It's a vicious cycle." ^[8]

Research shows that forests damaged by insects sequester 69% less carbon, while those affected by disease sequester 28% less. Overall, such damage reduces the carbon sequestration potential of U.S. forests by about 50 million tons of carbon dioxide annually ^[8].

Additionally, reduced rainfall and prolonged droughts make plants more vulnerable to certain diseases, while fluctuating moisture levels can worsen the spread of others. Whether regions experience wetter or drier conditions, gardeners and farmers are facing heightened disease pressures under changing climate conditions ^[10].

Combining Old Methods with AI Tools

Once you’ve accounted for local trends and selected the right plants, integrating AI tools can take your pest management to the next level. For example, at Organic Orchard in India, farmers combined an AI-based disease detection app with traditional fertilization practices like using oilseed cake to address nitrogen deficiencies. By sharing experiences and blending both approaches, they improved decision-making and strengthened their gardens against climate challenges ^[20].

"Traditional knowledge has its own importance, but when it comes to dealing with climate change, it will be important to use technology and take advantage of it. Both should be considered side by side."

• Farmer, Cereal Farm ^[20]
