Insect predator-prey relationship with lady beetle and aphids 🐞🦟🍅🍆🪴
🐞Lady beetles are voracious predators of aphids, which are common agricultural crops. They can feed on numerous aphids in a single day, helping to reduce aphid populations attacking the crop.
🥒While majority of them are important biological control agents, there are exemptions like the squash beetle which can be considered as pest.
🕷️Aside from aphids, which is known to be as their primary prey, lady beetles also feed on other soft-bodied insects like mealybugs, scale insects, and spider mites.
🚨The predation of aphids by lady beetles involves several key mechanisms.
📍Lady beetles have excellent vision and can spot aphids, through their bright colors and distinct shapes.
🧪Certain chemical cues (pheromones) are being released by aphids when they're under attack, which can attract lady beetles to the infested area.
💪🏼Lady beetles are also agile and can quickly capture their prey due to their strong, sharp mandibles. They use their mandibles to chew and consume aphids.
🔄During breeding cycles, lady beetles often lay their eggs near aphid colonies. When the eggs hatch, the larvae feed on the aphids, further contributing to pest control.
🍃Lady beetles reproduce quickly, and both adult beetles and their larvae are efficient predators, leading to a rapid reduction in pest populations.

Some interesting facts about potato late blight disease 🌱🚜🥔🍅🧫🔬🍂👨🏼🔬🧬
🦠Phytophthora infestans is an oomycete microorganism that causes serious disease known as potato late blight.
🗓️During 1840s, late blight disease was a major culprit of epidemics in the United States and expanded to Europe causing the Irish Famine (1845) and the Scottish Highland Potato Famine (1846).
📍This period is also known as the 'Hungry Forties' because that time many people starved due to lack of access to other staple food sources and also caused emigration of people.
🥔During that time, the most popular variety widely cultivated is the Irish Lumper. Due to its susceptibility to the pathogen, massive areas of potato fields were wiped out.
👨🏼🔬Due to great losses attributed to this, it paved opportunities for plant pathologists study the disease. The pathogen was first described by M. J. Berkeley and subsequently named Phytophthora infestans by Heinrich Anton de Bary in the 1870’s.
🧫De Bary worked out the life cycle of potato late blight pathogen and first to prove experimentally that Phytophthora infestans is the cause of potato late blight.
🔬He convinced the scientific community that the white sporulation on infected potato plants was the causal agent of the disease and not the result of spontaneous generation from the decaying vegetation or the wrath of God. He proved that fungi are causes but not the results of diseases.
🌎Years after this disease has been identified, debates have evolved on the center of origin of the pathogen: South America or Central Mexico.
📌Although it is widely accepted that Peru is the center of origin of potato, tomato and pear melon which are known hosts of the pathogen, it was not clearly proven to be center of origin of the pathogen.
👩🔬In 2014, Goss et al published their studies and finally elucidated the center of origin of the pathogen. They conducted phylogeographic and approximate Bayesian computation analyses to unraveling complex demographic histories of nuclear genes sampled from populations in the Andes, Mexico, and elsewhere using microsatellite markers and sequences.
🇲🇽They did not find support for an Andean origin of Phytophtora infestans; rather, the sequence data suggest a Mexican origin.
🌱The authors provided basis to understand the coevolution of hosts and pathogens which is vital in disease management programs to manage future epidemics of this disease.

Late blight of potato and tomato
Late blight is the disease that triggered the Irish potato famine of the 1840s. It also was the first plant disease for which a microorganism was proved to be the causal agent, leading to the birth of plant pathology as a science....
