Canadian Sophia Spencer, 8, loves bugs. A tweet her mom sent out about that made headlines and led to a paper the girl co-authored in a science journal. NPR's Ailsa Chang talks with Spencer and her co-author, scientist Morgan Jackson. [Copyright 2017 NPR]
High pesticide risk to honey bees despite low focal crop pollen collection during pollination of a mass blooming crop Article by Scott McArt, Ashley Fersch, Nelson Milano, Lauren Truitt, and Katalin Boroczky. Published April 19,2017 on Scientific Reports. http://www.nature.com/articles/srep46554
Managing agricultural pests with an incomplete understanding of the impacts that tactics have on crops, pests, and other organisms poses risks for loss of short-term profits and longer-term negative impacts, such as evolved resistance and nontarget effects.
For 25 years and Cornell University professor of entomology John Sanderson has brought the latest and safest in integrated pest management to greenhouse growers all over New York. Now, for his boundless enthusiasm and contagious love of learning, Sanderson has received an Excellence in IPM award from the New York State Integrated Pest Management Program (NYS IPM).
A much newer technology used in precision agriculture applications is aerial drones. Lindsay Chamberlain, a student at Cornell who works in Ketterings’ program and with drone expert Elson Shields, talked about some of the work they are doing with drones.
The call for citizens to become scientists is being issued from Cornell’s Lost Ladybug Project, a program founded at the university 16 years ago when the beetle’s disappearance was first deemed a crisis.
“It is true that honeybees are facing more threats today than they did 50 years ago. In particular, new parasites have been introduced to western honeybees. Although each decade has its own stresses with beekeeping, these new threats make it particularly difficult to keep bees healthy today,” said Emma Mullen, Cornell University honey bee associate and member of department of entomology.
New York and other regions in the United States are seeing greater numbers of invasive insects that attack specialty crops due to increased levels of interstate and international trade. Entomologists at Cornell’s New York State Agricultural Experiment Station (NYSAES) have taken the lead in addressing these destructive pests.
Anthony Auletta, a former Cornell Undergraduate, won 1st prize for his poster on spiders brains at the International Congress of Arachnology meetings in Golden, Colorado this week! Both Linda Rayor, former PI, and Cole Gilbert, former advisor, were in attendance.
New pathogen takes control of gypsy moth populations | Cornell ChronicleA new fungal pathogen is killing gypsy moth caterpillars and crowding out communities of pathogens and parasites that previously destroyed these moth pests.
In the face of scientific dogma that faults the population decline of monarch butterflies on a lack of milkweed and herbicides, a new Cornell study casts wider blame: sparse autumnal nectar sources, weather and habitat fragmentation.
When Prof. James Liebherr of the Cornell University Insect Collection thoroughly sampled beetle populations on the volcano, he identified 116 species of round-waisted predatory beetles, including 74 new to science.
NNYADP alfalfa snout beetle project boosts growers and agribusinesses | Dairy Herd ManagementCornell University entomologist Elson Shields and research support specialist Antonio Testa discovered native New York nematodes as a naturally occurring biological control for alfalfa snout beetle (ASB), and pioneered the use of the insect-attacking, microscopic worms to reduce beetle populations to manageable levels.
Biotechnology companies hope to turn a Nobel-prize-winning discovery into a powerful genetic control for pest weeds and insects. RNA interference (RNAi) holds the promise of delivering modern agricultural systems a target-specific control method, with no known impact on surrounding ecosystems.
“Soil insecticides were effective, but costly, time-consuming, didn’t cure the problem and are no longer an option,”Rulfs explains. “Adult control with foliar insecticide is ineffective.” That’s why Rulfs Orchard was the first berry farm to test a biocontrol protocol developed by Cornell University entomologist Elson Shields.
"Diamondback is a serious problem for farmers in New York State and around the world – anywhere cruciferous vegetables and field crops are grown," he said. "These moths invade and attack the crops, and they are developing resistance to insecticides, so we urgently need new tools to better control them."
Although invasive beetles may probably never be eradicated, local farmers are winning battles against them, according to experts from Ithaca’s Cornell University and Cornell Cooperative Extension of Jefferson County.
New research improves prospects of plum curculio control using nematodes. New York fruit growers may have found a more effective biocontrol tool for managing plum curculio—and a new model that could be developed and used by growers elsewhere.
