Camera Traps Reveal the True Culprit Behind Crop Damage in Honduras 

Using noninvasive monitoring in eastern Honduras, researchers found that small mammals, not large wildlife like tapirs, drive cassava crop loss, highlighting the need for evidence-based, wildlife-friendly solutions.

Today, 29th June, marks the International Day of the Tropics, a day that reminds us of why understanding tropical ecosystems matters for both wildlife and the communities that depend on them. This new study from the Honduran Mosquitia is a perfect example. 

A new study from the Honduran Mosquitia shows how simple, non-invasive technology can help solve one of the most common challenges in wildlife conservation: identifying the species actually responsible for crop damage. The full detailed results have been published in the open-access peer-reviewed journal Neotropical Biology and Conservation.

Across tropical landscapes, people living near forests often share the same concern: wildlife entering agricultural fields and feeding on crops. In many cases, these interactions can generate tension between local communities and conservation efforts, particularly when threatened species are perceived as the main culprits.

In the Indigenous Miskitu community of Mavita, in eastern Honduras, local people have long reported losses in their cassava (Manihot esculenta) fields, locally known as yucales. Most residents believed that the damage was caused by Baird’s tapir (Tapirus bairdii), an endangered species and the largest terrestrial mammal in Central America. They also suspected that pacas (Cuniculus paca) and armadillos (Dasypus mexicanus) were contributing to crop losses.

But was the tapir really responsible?

To answer this question, researchers from the Wildlife Conservation Society (WCS) installed camera traps equipped with solar-powered motion-activated LED lights around a 10-hectare cassava field located within a mosaic of Caribbean pine forest and tropical rainforest in the Honduran Mosquitia.

The goal was to document which mammals were actually visiting the crops and evaluate whether these light systems could eventually help reduce crop losses. 

Following the evidence

Over two months of monitoring, the cameras recorded seven mammal species, including tapirs, ocelots, jaguarundis, agoutis, opossums and rabbits. 

Contrary to local perceptions, the species most frequently detected interacting with cassava crops was not the tapir, but the Honduran cottontail rabbit (Sylvilagus hondurensis) – a species that locals did not even know occurred in their plantations. The cameras also found no evidence that armadillos or pacas were feeding on the cassava.

Meanwhile, tapirs were present in the area, but appeared far less frequently than expected. 

Many conservation conflicts begin with assumptions. Without evidence, it is easy to blame large and conspicuous animals. Camera traps allowed us to identify which species were truly interacting with the crops and helped us separate perception from reality.

Why does this matter?

Correctly identifying the species involved in crop damage is more important than it might seem.

Across Latin America, wildlife is often persecuted after being blamed for agricultural losses. In Honduras, Baird’s tapir has historically faced retaliatory hunting in areas where farmers perceive it as a threat to their crops. 

When damage is incorrectly attributed to threatened species, conservation efforts can be undermined while the actual source of the problem goes unaddressed. 

The study highlights how non-invasive monitoring can provide communities and conservation practitioners with reliable information before management decisions are made. 

Technology for coexistence

The project also tested the use of solar-powered motion-sensor lights, sometimes referred to as “silent technology,” as a tool to monitor and potentially deter wildlife activity.

Researchers found that different species reacted differently to the lights. Tapirs tended to show stronger behavioral responses, while rabbits often continued moving through the area despite illumination. These findings suggest that no single deterrent works for every species and that mitigation strategies should be tailored to local ecological conditions.

More importantly, the technology proved valuable as a diagnostic tool, helping researchers understand not only which species were present, but also when they were active and how they responded to human-made stimuli. 

Conservation begins with understanding

The forests of the Honduran Mosquitia harbor some of the most important wildlife populations remaining in Central America. Yet the long-term conservation of these species depends not only on protecting habitat, but also on fostering coexistence with local communities. 

What surprised me most was discovering that the species most frequently blamed by local people was not the one causing most of the crop interactions.

This study demonstrates that effective conservation starts with understanding what is actually happening on the ground. Sometimes the evidence confirms what people already suspect. And sometimes it reveals that the animal everyone blamed was innocent all along.

Scientists forecast where is the highly invasive fall armyworm to strike next

Staple and economically important crops throughout the world could be at serious risk if efficient measures are not taken soon

Known to be feeding on many economically important crops cultured across the world, including maize, rice, sugarcane, sorghum, beet, tomato, potato, cotton and pasture grasses, the larvae of the native to the Americas fall armyworm moth seem to have already found a successful survival strategy in a diverse and changing world.

Furthermore, having taken no longer than 2 years to invade and spread throughout most of sub-Saharan Africa, the pest has already demonstrated its huge potential in severely affecting livelihoods around the globe.

A recent study in the open-access journal NeoBiota, conducted by Dr Regan Early of Exeter University, United Kingdom and her colleagues at the Centre for Agriculture and Bioscience International: Dr Pablo González-Moreno, Sean T. Murphy and Roger Day, looks into the factors and likelihood for the fall armyworm (Spodoptera frugiperda) to spread to other regions and continents.

Invasion progress

The alarming reports started in January 2016 when major outbreaks of fall armyworms were registered in Nigeria and Ghana, preceding signals from Benin, Sao Tomé and Togo shortly after. By September 2017, the pest had already been confirmed in 28 sub-Saharan African countries, with nine states expected to follow suit.

While unaided dispersal of the species in Africa is considered unlikely, it is speculated that the pest had arrived on a passenger flight from America. To back this theory, the researchers point out that the first countries to house the invader are also the major air transportation hubs in Africa and have warm, moist climate similar to those in the pest’s natural habitat.

In the aftermath, recent estimates point to up to 50% maize yield loss in Africa attributed to the fall armyworm. However, scientists believe that the species is far from finished spreading and is highly likely to invade new continents.

Who’s next?

To find what makes a region an inviting new habitat for the fall armyworm, hence which countries face the highest threat of future invasions, the researchers looked into both the native and African distributions of the species, and the effects different temperatures and precipitation levels have on it.

Having concluded that the lowest temperatures and the maximum amount of rain play the main role in determining whether the fall armyworm is to establish in a certain region, the scientists concluded that South and Southeast Asia, as well as Australia face the most serious risk, since their climate is very similar to the one preferred by the pest.

However, the authors of the study remind that this forecast shall in no way be taken with a sigh of relief by countries with milder climatic conditions. While the moth needs particular temperature and precipitation amplitudes at its year-round habitat, it could easily travel back and forth up to several hundred kilometres during its seasonal migrations. Therefore, if the fall armyworm establishes in North Africa, it could migrate to Europe during the warmer months, just like it has already been observed to travel from its year-round localities in Argentina, Texas and Florida all the way to Canada’s Québec and Ontario in the north.

The increasing transportation and international trade are also likely to facilitate the further spread of the fall armyworm outside Africa. The scientists conclude that, given the current travel air routes, it is Australia, China, India, Indonesia, Malaysia, Philippines and Thailand which are at high risk of becoming the pest’s new habitat.

What’s next?

Having concluded that there is a considerable potential for near global invasion and seasonal migration of fall armyworm, the scientists call for vigilance from farmers and programme managers alike. They remind that early detection of small larvae is crucial, since it is only at this stage that chemical insecticides would work effectively.

“As fall armyworm has huge potential to affect staple and economic crops globally, we urgently need information on the pest’s potential distribution and environmental limitations,” comment the researchers.

“Management decisions would be improved by further research on fall armyworm’s seasonal migration and population dynamics and the environmental dependency of interactions with other species.”
