Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
In the UK, "30 to 60% of species per order have declining ranges". Insect pollinators, "needed for 75% of all the world's food crops", appear to be "strongly declining globally in both abundance and diversity", which has been linked in Northern Europe to the decline of plant species that rely on them.
Peto's paradox is the observation that, at the species level, the incidence of cancer does not appear to correlate with the number of cells in an organism. [1] For example, the incidence of cancer in humans is much higher than the incidence of cancer in whales, [2] despite whales having more cells than humans.
Monarch butterflies, known for migrating thousands of miles (km) across North America, have experienced a decades-long U.S. population decline due to habitat loss caused by human activities such ...
In China, hand pollination of apple orchards is labor-intensive, time-consuming, and costly. [204] [205] In regions of the Old World where they are indigenous, honeybees (Apis mellifera) are among the most important pollinators, vital to sustain natural habitats there in addition to their value for human societies (to sustain food resources).

Honeybees and bumblebees can also act as pollinators of crop species. Although pollination can be achieved during pollen transport via wind, a large amount is also achieved via insect, specifically bee transport. In 1986, there was an estimated 17,000 million worth of crops that were solely pollinated by insects in the United States. [21]
The bugs were responsible for killing 42 people in China in 2013. In North America, they first appeared in 2019, being seen in British Columbia in August of that year, and in Washington state in ...
It is applied to infected soil and will kill fungus gnat larvae for 30–60 days from a single application. Its mechanism of action is to interfere with chitin production and deposition and it also triggers insect larvae to molt early without a properly formed exoskeleton, resulting in the death of the larvae. Although it is targeted at fungus ...
