The Shocking Truth: What Really Happens When You Eat a Navel Orangeworm

Have you ever taken a bite of a delicious navel orange, only to find an unwelcome guest wriggling inside? If so, you may have encountered the infamous navel orangeworm. This tiny pest has become a major headache for farmers and consumers alike, causing millions of dollars in crop damage each year. But what happens if you accidentally swallow this pesky intruder? In this article, we will delve into the world of navel orangeworms and explore the potential effects on human health if one were to make its way into your stomach. So, before taking another bite of that juicy orange, let’s find out what exactly happens if you eat a navel orangeworm.

The Navel Orangeworm: A Common Pest in Citrus Orchards

The navel orangeworm (Amyelois transitella) is a common pest that affects citrus orchards throughout California. It is an insect that can cause significant damage to crops, especially the nuts and fruits of various trees. This includes almonds, pistachios, and most importantly, oranges. These pests usually attack these crops during the growing season by boring into the fruit and feeding on it.

One reason why the navel orangeworm poses a serious threat to citrus orchards is due to its breeding rate. A single female can lay up to 500 eggs in her lifetime, with each egg taking only a few days to hatch into larvae. Therefore, it does not take long for this pest population to explode in citrus orchards, leading to significant crop damage and financial losses for farmers.

The navel orangeworm is native to North America and has been a major concern for farmers since the early 1900s. Its name comes from its tendency to lay eggs at the navel or stem ends of fruits (known as the “navel”), where they are well-protected from predators and pesticides.

The Life Cycle of a Navel Orangeworm

To understand how navel orangeworms can cause damage in citrus orchards, it is important to know their life cycle. The duration of their life cycle varies depending on temperature and other environmental factors, but it typically takes around 4-6 weeks from egg laying to adult emergence.

The first stage is the egg stage, where adult females lay eggs on host fruits during springtime. These eggs then hatch into tiny larvae that feed on plant materials exclusively. The second stage is known as larva or caterpillar stage, where they undergo several molts before reaching maturity. The larvae remain inside the fruit, consuming its flesh and seeds, causing significant damage to the fruit’s appearance and quality.

In the third stage, the larvae pupate inside the fruit or on nearby trees, forming a cocoon. The pupal stage lasts for about 9-11 days, after which adult moths will emerge. These moths are weak fliers and are responsible for continuing the cycle by laying eggs on new host fruits.

The Impact of Navel Orangeworms on Citrus Orchards

Navel orangeworms can significantly impact citrus orchards in several ways. For one, their physical damage to fruits reduces their market value, affecting farmers’ profits. Additionally, damaged fruits become more vulnerable to secondary infections from bacteria and fungi, leading to further losses for farmers.

Moreover, navel orangeworms can decrease the overall yield of a citrus orchard. As they consume large portions of fruits and in some cases bore through multiple fruits before pupating, they limit the number of fruits available for harvesting at the end of the season.

Furthermore, navel orangeworms can also cause indirect damages to citrus orchards. They create entry points for other pests and diseases through their feeding activities that can cause further damage to crops. Additionally, excessive use of pesticides to control these pests can harm beneficial insects and result in pest resistance over time.

Methods of Controlling Navel Orangeworm Infestation

Controlling navel orangeworm infestation is essential for preserving citrus orchard yields and protecting profits for farmers. There are various methods available that aim to prevent this pest’s spread or eradicate them from affected areas effectively.

One method is cultural control practices that involve cultural practices like pruning to reduce shelter and sanitation measures like cleaning fallen nuts or fruit off the ground regularly. These practices aim to remove environments where navel orangeworms thrive and reduce their populations without using chemicals.

Another method is the use of pheromone traps to capture adult male moths. By tracking the number of male moths caught in a trap, farmers can determine the need for other control techniques and assess the effectiveness of their strategies.

Chemical control methods involve the use of insecticides to kill or disrupt navel orangeworms’ development stages, ultimately reducing their populations. However, overusing these chemicals can lead to adverse effects on beneficial insects and pollinators. Therefore, it is best to consult with a pest management professional before using any insecticide.

What Happens If You Eat a Navel Orangeworm?

Navel orangeworms are not harmful or poisonous to humans if accidentally consumed. In fact, it is unlikely that you will ever come across one in a fruit you purchase from a store as strict quality control processes are in place to prevent infested fruits from reaching consumers.

However, if you consume fruits from your backyard citrus tree that may have been infested with navel orangeworms, it is recommended to thoroughly wash and inspect them before eating. Consuming fruits with live larvae and eggs may cause gastrointestinal irritation and discomfort for some individuals.

What is a Navel Orangeworm?

The navel orangeworm (Amyelois transitella) is a common pest that affects various types of crops, particularly nut-bearing ones such as almonds, pistachios, and walnuts. Native to North America, this insect belongs to the family of moths known as Pyralidae and can be found in parts of California, Arizona, and Nevada. The name “navel” comes from the insect’s habit of entering fruits through their navels or attachment points, while “orangeworm” refers to its original host – oranges.

Life Cycle and Reproduction

The navel orangeworm follows a typical moth life cycle: egg, larva/caterpillar, pupa, and adult. Adult moths usually emerge from August to mid-September but can vary depending on environmental conditions. They are mostly active during the night when they seek out potential mates. Once they find a suitable partner, mating occurs before the female moth lays her eggs on the surface of fruits or trees’ crevices.

The laid eggs hatch after four to six days into larvae or caterpillars that will feed on nuts or dry fruits like figs for about three weeks. Larvae have different color variations but can be identified by their distinct pair of brown stripes running alongside their bodies. After feeding on their hosts’ solid parts like kernels or pistils in fruits like figs for about three weeks, they leave them as mature larvae with dry skins.

The Effects of Infestation

Navel orangeworm infestation can lead to notable losses to nut producers worldwide due to financial concerns and nut quality reduction caused by food contamination. According to USDA research data commissioned in 2017 by the Almond Board of California (ABC), growers are not taking appropriate cultural-measure practices timely, leading to their annual loss of around $60 to $100 million. Severe initial damage such as shell piercing allows mold and aflatoxin contamination observed in almond kernels. Infested almonds possess less value in terms of exported foreign crops and can incur processing discounts.

Methods of Control

Growers turn to available cultural and chemical practices to fight the navel orangeworm menace. In traditional methods to control insect infestation, growers rely initially on crop cultural practices that encourage wildlife predators that help lower sooner pest populations.

In addition, proper handling techniques during nut processing such as drying and sorting can help prevent contamination by reducing the chances of nuts exhibiting signs of damage. Awareness and appropriate preventive actions on the part of growers are essential in maintaining sustainable nut production while minimizing losses due to navel orangeworm infestation.
