You might want to check out 'Insect-Free World Dystopia'. It explores how various ecosystems collapse and human society adapts in a world deprived of insects. The characters face numerous challenges and moral dilemmas.
One common theme is ecological collapse. Insects play a crucial role in pollination, decomposition, and as a part of the food chain. In a world without them, plants would die, leading to a lack of food. Another theme is the disruption of the circle of life. Insects are prey for many animals, so their absence would cause a domino effect on the entire ecosystem. For example, birds that rely on insects for food would starve. Also, there might be a theme of human desperation as they try to find ways to survive without the essential services that insects provide.
One such book is 'The Bees' by Laline Paull. It's not exactly about a world without insects but gives a great perspective on the complex society of bees. If the bees were to disappear in our world, it would have a huge impact on ecosystems, much like in a world without insects in general. Another could be 'The Windup Girl' by Paolo Bacigalupi, which depicts a post - apocalyptic world with a disrupted ecosystem where many species, including insects, are severely affected. It shows how the lack of certain elements like insects can lead to a dystopian state.
You could try 'Insectless Utopia'. It explores how human society copes when insects disappear, including changes in agriculture and food chains.
One possible plot could be about the collapse of the ecosystem. Without insects, plants that rely on them for pollination start to die off. This leads to a shortage of food for herbivores, which then affects the entire food chain. Eventually, humans face a severe food crisis and have to find ways to genetically engineer plants to self - pollinate or develop artificial pollinators.
The setting would likely be a desolate place. Gardens would be full of wilting, unpollinated flowers. Fields would have sparse crops as they lack the help of insects for pollination and pest control. There would be an eerie silence without the buzzing of bees or the chirping of crickets at night.
In a world without insects fiction, the plot could involve a mystery. Scientists start to notice strange things happening, like certain diseases becoming more prevalent. They eventually realize it's because of the lack of insects. The story could then follow a detective - like scientist who tries to figure out how to bring insects back. They discover that a powerful corporation was behind a chemical release that wiped out the insects, and they have to fight against the corporation's attempts to keep the status quo to save the planet.
In such a fictional world, ecosystems would collapse. Insects play crucial roles in decomposition and as a food source for other animals. The lack of them would have cascading effects on all life forms.
Human society would become much less diverse. Insects support a vast number of species, and without them, many birds, fish, and small mammals would die out. This would mean less biodiversity in our environment, which could lead to a more monotonous and less - resilient ecosystem. In terms of our built environment, we'd likely see an increase in pests that are not insects but thrive in the absence of their natural competitors. For example, spiders that used to feed on insects might start to invade human - occupied spaces more often in search of other food sources, causing problems for people.
Another book might be 'Divergent' by Veronica Roth. In this dystopian world, society is divided into factions based on different virtues, and the main character, Tris, discovers she doesn't fit neatly into any one of them. It explores themes of identity and conformity.
One of the great ones from such a collection might be 'Fahrenheit 451' by Ray Bradbury. In this dystopian world, books are burned to suppress ideas. Also, 'The Handmaid's Tale' by Margaret Atwood is very relevant. It depicts a future where women are subjugated and used for reproduction in a theocratic regime.
