Discovery of amber-trapped insects offers new insights into ancient Amazon rainforest
Scientists have identified prehistoric insects preserved in amber in South America for the first time, offering rare insight into life on Earth more than 100 million years ago, when flowering plants were just beginning to spread across the globe.
The discovery was made at a sandstone quarry in Ecuador, with many of the amber specimens dating back about 112 million years, said Fabiany Herrera, curator of fossil plants at Chicago’s Field Museum and co-author of the study published Thursday in Communications Earth and Environment.
Until now, almost all amber deposits from the past 130 million years had been found in the Northern Hemisphere. Their absence in southern regions of the ancient supercontinent Gondwana had long puzzled scientists, said David Grimaldi, an entomologist at the American Museum of Natural History who was not involved in the research.
For the first time, researchers have found fossilized beetles, flies, ants and wasps in South American amber, confirmed Ricardo Pérez-de la Fuente, a paleoentomologist at Oxford University Museum of Natural History.
“Amber pieces are little windows into the past,” Pérez-de la Fuente said, noting that the find will help scientists trace the early interactions between flowering plants and insects during the dinosaur era.
The team uncovered hundreds of amber fragments containing insects, pollen and tree leaves at the quarry, which lies on the edge of today’s Amazon basin. But Herrera said the prehistoric rainforest looked very different from the one we know now, with ferns and conifers — including the distinctive Monkey Puzzle Tree — that no longer exist in the region.
“The forest back then was not like the Amazon we see today,” Herrera explained.
The amber deposits had been known to local geologists and miners for years. Study co-author Carlos Jaramillo of the Smithsonian Tropical Research Institute first learned about them a decade ago and later pinpointed their location through field notes.
“I realized this place is extraordinary,” Jaramillo said. “There’s so much amber in the mines, and it’s easier to spot in the open quarry than in dense forest cover.”
Scientists plan further analysis of the amber to shed light on Cretaceous biodiversity — particularly how insects shaped the evolution of flowering plants.
“Amber tends to preserve the tiniest of details,” said Grimaldi. Pérez-de la Fuente added: “This was the period when insects and flowering plants began their relationship — and that turned into one of nature’s most successful partnerships.”

How to get rid of cockroaches, bugs at home without using insecticide
Dealing with cockroaches and bugs can be a pain, especially when they invade your kitchen and home. While conventional insecticides are commonly used to destroy these pests, they often contain harmful, toxic chemicals that can pose risks to human health and the environment. Fortunately, there are several natural methods you can apply to get rid of cockroaches and bugs without using harsh insecticides. This article will explore some effective techniques that can help you keep your kitchen and home cockroach- and bugs-free.
How pesticide can be harmful to health
Exposure to toxic insecticides used for killing cockroaches can pose significant threats to human health. Some chemicals designed to kill pests can also have adverse effects on humans. When insecticides are applied at home or other indoor spaces, they can contaminate the air we breathe -- leading to respiratory problems such as coughing, wheezing, and irritation of the throat and lungs.
Prolonged exposure or excessive use of these chemicals has been linked to more severe health issues, including allergic reactions, skin rashes, headaches, nausea, and even neurological disorders. Additionally, children are particularly vulnerable to the harmful effects of insecticides due to their size and developing immune system.

10 completely safe ways to get rid of cockroaches and bugs at home
Leave no dirty dishes in the sink
Leaving no dirty dishes in the sink is an important practice to prevent the presence of bugs and cockroaches in your kitchen and home. When dishes and utensils are left unwashed and pile up in the sink, they become a potential food source for pests. The leftover food particles and residues on the dishes attract insects, including cockroaches, ants, and flies.
To avoid this, make it a habit to clean your dishes promptly after use. Wash them with hot, soapy water, ensuring that all food residues are removed. If you are unable to wash them immediately, at least rinse off the leftover food before placing them in the sink.
Clear your garbage
Clearing up your garbage is crucial to preventing the presence of bugs and cockroaches in your kitchen and home. Pests are attracted to the odor and food waste in the garbage, making it a potential breeding ground for infestations.

To effectively manage your garbage, use a sealable trash bin with a tight-fitting lid to contain odors and deter pests. Dispose of your garbage regularly to avoid the buildup of food waste and odors that attract bugs and cockroaches. Double-bagging is particularly strong for wet garbage. Make sure to properly secure trash bags before placing them in the bin.
Clean the food crumbs
Cleaning up food crumbs is essential for preventing the presence of bugs and cockroaches in your kitchen and home. Crumbs and food particles left on countertops, tables, and floors serve as a tempting food source for pests. To effectively prevent infestations, make it a habit to clean up food crumbs promptly. Regularly sweep or vacuum your kitchen and dining area to remove any stray crumbs.
Use baking soda
To effectively stop the invasion, a blend of baking soda and sugar proves to be a highly efficient technique. Sugar acts as an attractive agent for cockroaches, while baking soda kills them. To effectively address the issue, it is crucial to identify the hiding spots of the pests and generously apply the mixture to the corners.

Effective Ways to Keep Insects, Bugs Out of Your Home
Seal Your Doors
A properly sealed door can help keep out unwanted pests. It is efficient just like a locked door that can keep burglars out. You will be surprised to see that there are a number of unsealed gaps in your doors, each of which makes an easy entrance path for bugs. You can install an aluminum threshold under the door to prevent insects from crawling under your door.

Maintain Your Yard
Yard maintenance can prevent bug invasions, especially in the case of mosquitoes and fleas. Mosquitoes breed easily in the stagnant clean water. Storage of pooled water in your yard can enhance the mosquito population. So, you need to replace the water of your swimming pool regularly.
When you are watering plants into your yard, let the water get naturally absorbed into the soil. After rain let the stagnant water pass through the drainage system.
Besides, you must pay attention to the drainage system of your yard, which is related to the slope of the earth. Make sure your yard’s regular drainage channels are properly maintained. Try to keep the drainage channels free from leaves, grass clippings, and debris so they are able to operate effectively. This will reduce the number of bugs that are trying to enter your home.

Add Screens
A little hole can allow pests to crawl through so make sure there are no holes in your screen. Many people like natural ventilation from doors and windows to bring fresh air into the home, especially in the summer season. But it is a matter of sorrow that summer is the worst time of the year for mosquitoes, fleas, and other pests to invade your home.
If you wish to enjoy the fresh air without the annoyance of insects, install screens on windows and doors. However, you need to make sure that you seal all tiny holes to prevent insect entry.
Cover Large Openings
If there is a hole in your roof, it allows all the bugs — and bigger intruders into your home. You can fill larger openings and keep bugs out by using very fine wire mesh, often called hardwire cloth. However, you need to check to see if yours are operating properly and repair or replace the dampers as necessary.
