         Cotton bollworm battles against helicoverpa armigera nuclear polyhedrosis virus

                              (hereinafter referred to as virus agent)

 

The hilarious showdown between Virus Agent and Cotton bollworm:

 

Act 1: The appearance of the villain - the arrogant daily life of the cotton bollworm

The cotton bollworm, known as the "agricultural tyrant", lives up to its name. Its motto is: "As long as I chew fast enough, pesticides won't catch up with me”

**Pest design tag

- Perpetual eating machine: It can devour 10 cotton leaves in a single day, and even eat the corn when it's hungry.

- Drug-resistant Madman: With an ancestral drug-resistant gene, he can drink DDT like cola and spray dichlorvos like perfume.

- Master of Escape: He pretends to be dead and lies flat during the day, but commits crimes wildly at night, and even farmers with flashlights can't catch him.

One day, a mysterious slogan appeared in a cotton field in Xinjiang: "No gifts this year due to pest infestation; only cotton husks will be accepted as gifts!" - declared by the cotton bollworm gang.

 

Act 2: The Skyfall - HaNPV Virus Special Forces

When the human pesticide defense line was on the brink of collapse, the "Avengers" of nature dispatched the ultimate weapon - HaNPV Virus Special Forces

**Virus Agent Archives**:

- **Master of Disguise**: Wrapped in a sweet protein "candy coat", it deceives the cotton bollworm into a single gulp.

- **Splitting Expert**: After entering the insect body, it can replicate 1 billion clones within 48 hours, staging an "Insect Version of Train to Busan".

- **Environmentalists**: Targeting pests exclusively, saying "See you tomorrow" to bees and butterflies.

 

**Classic combat record**:

- **Chili Field Blitz**: Taking advantage of the cotton bollworm larvae's "eating broadcast", virus agents sneak into the chili sauce, wiping out the insect population within 72 hours. The chili peppers are delighted to see themselves trending on social media: #Thank you, virus buddy, for the rockets you've sent#

- **Cotton Field Infernal Affairs**: The virus solution was disguised as "cotton-flavored milk tea", and the greedy larvae were all poisoned. Before dying, they even posted on their social media accounts: "This batch of pesticide... actually tastes a bit good?"

 

**Act 3: The Insect's Counterattack - How to Die Elegantly**

The leader of the cotton bollworm held an emergency meeting: "Brothers! Nowadays, pesticides are mixed with water, and viruses are mixed with sugar. This generation of humans has no sense of morality!"

**Confusing behavior of insects**:

1. **Pretend to be picky**: Choose to eat only the leaves that haven't been sprayed with virus, only to end up with virus smeared all over the face by the wind.

2. **Staying up late to cultivate**: Trying to avoid the virus by adopting the "day and night reversal diet method", but unexpectedly, the virus agent comes equipped with a 24-hour night vision device.

3. **Online SOS**: @Drug-Resistant Gene: "Are you there? Can you evolve an antiviral skill?" Gene replies: "The function you called has not been developed yet..."

 

**Virus 2.0 Upgrade Package**:

- **Collaborative combat with Bacillus thuringiensis (Bt)**: The virus and bacteria work together to combat pests, leaving them no place to escape.

- **UV protectant**: With the addition of UV protectant, viruses are no longer afraid of the sun, and their fighting ability is unparalleled.

- **Virus Master**: Modify the virus agent to make it firmly adhere to the leaves, waiting for the insects to be hooked.

 

A precious video has emerged from a laboratory: a cotton bollworm infected by the upgraded viral agent is dancing to "Jile Jingtu" while emitting rainbows, which can be regarded as a grand display of bewildering behavior in the insect world.

### **Ultimate Easter Egg: The Final Words of the Insect Race**

As the leader of the cotton bollworm neared his end, he issued a call to his fellow insects:

"The three things I regret most in my life are:

First, I should not eat genetically modified cotton.

Second, I should avoid drinking afternoon tea contaminated with viruses.

"Third, I shouldn't have done... Not laying the eggs in the doctor's coffee cup!"

 

### **Behind the Scenes**

- **Exclusive interview with a bee journalist**: "Thanks to buddy the virus for providing us with a pollution-free garden. This year's honey sweetness has increased by 99%!"

- **Spider Internet celebrity live broadcast**: "I used to be exhausted chasing pests, but now I just sit back and wait for 'virus takeout' to arrive. It's so satisfying!"

 

**Scientific Trivia**:

1. Each poisoned cotton bollworm is equivalent to one "virus bomb", capable of infecting up to 30 square meters of farmland.

2. Virus agents are sensitive to ultraviolet light, so intelligent humans always send them on missions on cloudy days.

This "Hunger Games" in the microcosm ultimately ended with a resounding victory for the virus agents. As a ladybug, who wished to remain anonymous, said, "Since using HaNPV, my back doesn't ache, my legs don't hurt, and I have the energy to catch pests!"
