"Insects" calls for submissions to special issue, "Locusts and Grasshoppers: Biology, Ecology and Management"

January 15, 2020

Locusts and grasshoppers (Orthoptera: Acridoidea) are among the most serious agricultural pests worldwide. By inflicting damage to pasturelands and a wide range of crops, they jeopardize food security and livelihoods of about 10% of the world’s population. Their outbreaks, which in case of locusts can escalate to transcontinental plagues, require huge efforts of national plant protection agencies and international cooperation to control them. Being extremely adaptable to recent climate changes, locusts and grasshoppers present new challenges to researchers and pest managers. The current Special Issue addresses some of the newest insights surrounding biology, ecology and management of these ancient enemies of agriculturists.

With that, the journal “Insects” (Impact Factor 2.139) just published a call for submissions to the Special Issue "Locusts and Grasshoppers: Biology, Ecology and Management."

GLI, SENAVE fund regional cooperation on South American locust research and management

August 14, 2019

SENAVE conference presentersAfter 60 years of only small sporadic outbreaks of the South American locust, in 2015–17, a large upsurge led to damaging outbreaks in Argentina and Bolivia, requiring declarations of national emergencies in these countries (Medina et al. 2017). These outbreaks have continued into 2018–19, with numerous outbreaks in the Gran Chaco region of Paraguay which have now spread south in Argentina as far south as Santiago del Estero.

In response to these outbreaks, on April 8, 2019, a conference was held at SENAVE (Servicio National de Calidad y Sanidad Vegetal y Semillas) headquarters in Asuncion to discuss whether Paraguay should declare a national emergency. The conference included presentations by Hector Medina (Servicio Nacional de Sanidad y Calidad Agroalimentaria, SENASA-Argentina), Fernando Copa Bazan (Universidad Autonoma Gaston René Moreno, Santa Cruz, Bolivia), Jon Harrison (School of Life Sciences, Arizona State University), and Julio Rojas (SENAVE-Paraguay), and was attended by numerous SENAVE administrators including the Director of Dirección de Protección Vegetal, Ing. Agri. M.Sc. Ernesto Galliani.

Mira Word post graduate review and update

July 23, 2019

researchers taking samples from a fieldThis post was written by Mira Word who completed her Sustainability M.Sc. in May 2018 in Arizona State University's Cease Lab, collaborating with the Senegalese Plant Protection Directorate (DPV).

During her time at ASU, Mira studied the interactions among farmer livelihoods, agricultural practices, soil, plant nutrients and the Senegalese grasshopper (Oedaleus senegalensis), as well as other grasshoppers in the Kaffrine region of Senegal. Oedaleus senegalensis is a non-model locust, forming swarms, migrating across national borders, and is a major pest of cereal crops in the Sahel. Prompted by her recently-published thesis paper “Soil-targeted interventions could alleviate locust and grasshopper pest pressure in West Africa”, we asked her to reflect on her time as a grad student at ASU and member of the Global Locust Initiative.

Postdoctoral researcher Marion Le Gall reviews summer 2018 fieldwork

March 14, 2019

Marion Le Gall and men posing for pictureThis post was written by Marion Le Gall, a postdoctoral researcher in Arizona State University's Cease Lab.

Last summer, with Master of Science in sustainability student Mira Word having brilliantly defended her thesis and Arianne Cease in writing jail, I (Marion Le Gall) found myself the sole member of the Arizona State University Senegal field team. With that in mind, I decided that the reasonable thing to do was to craft not one, but two field seasons for myself.

At the end of July, I thus packed the material wood hutsI needed and took the long flight to Senegal. What didn’t take long was being reacquainted with the local rhythm. By that I mean that five hours before landing I still didn’t know where and who my Airbnb host was… Not to worry, in a country that prizes itself for its sense of hospitality, the famous Senegalese “teranga,” everything always seems to work out.

Annual review of entomology update

February 27, 2019

entomology figure 1

As we discussed in earlier news posts, preventive locust management has the potential to severely reduce the impact of locust outbreaks if resources and coordination can appropriately align (Figure 1). Nonetheless, to be successfully implemented, preventive strategies are still in need of some research and further refinement. Many of the Global Locust Initiative’s partner organizations are continuously working towards improving preventive management, including some participants of GLI’s First International Conference in April of 2018.

Several of these individuals—Long Zhang, Michel Lecoq, Alexandre Latchininsky, and David Hunter—recently published an article in Annual Reviews of Entomology, Locust and Grasshopper Management, highlighting advances in preventive management and opportunities for future research and improvement. The last comprehensive review of this kind was published in 1960.

Sustainability scientist Arianne Cease wins New Innovator Award

December 17, 2018

Arianne Cease headshotThe Foundation for Food and Agriculture Research (FFAR) announced today that Arianne Cease, director of the Global Locust Initiative in the Julie Ann Wrigley Global Institute of Sustainability, is one of nine recipients of its 2018 New Innovator in Food and Agriculture Research Award.

The purpose of the award is to invest in budding scientists in the food and agriculture field. According to FFAR, “The award recipients were selected on a number of criteria including scientific merit, innovation and a demonstrated commitment to mentoring other young scientists.”

The nine scientists win a total of $2.3 million over three years, and Arizona State University will match the funds given to Cease as a stipulation of the grant. Cease’s work explores the connections between land-use practices and locust outbreaks, and identifies and addresses barriers to sustainable locust management. The Global Locust Initiative also recently won a major grant from the Office of U.S. Foreign Disaster Assistance.

“Locust plagues are a global challenge that requires a team effort to address, and I’m excited to see FFAR support our cross-sectoral, interdisciplinary and transboundary approach,” Cease said. Cease is the only scientist from Arizona to win a New Innovator Award this year.

Global Locust Initiative wins USAID/OFDA grant to launch pilot project in Senegal

View Source | November 28, 2018

Arianne Cease wearing gloves working in a labLocusts have afflicted humanity throughout history, with devastating consequences. It’s no surprise that locusts are one of the 10 plagues in the biblical book Exodus. These insects are species of grasshoppers that can swarm in the millions and wipe out fields of crops in the blink of an eye.

The Global Locust Initiative, an Arizona State University program aiming to study and manage locust outbreaks, recently won a half-million-dollar grant from the Office of U.S. Foreign Disaster Assistance (a part of the U.S. Agency for International Development). This is the first time an ASU program has been awarded an OFDA grant, according to research advancement manager Ann Marie Hess, whose dedication to this partnership and work as a research advancement manager, alongside program manager Ariel Rivers, was critical to landing the grant.

With this funding, the Global Locust Initiative team — directed by senior sustainability scientist Arianne Cease — will test whether soil amendments to millet fields in Kaffrine, Senegal, decrease locust outbreaks, improve millet yields and increase farmer livelihoods.

Webinar discusses preventative locust management

November 8, 2018

locust swarm against blue skyOne of the differentiating characteristics between grasshoppers generally and locusts specifically is the potential for locusts to undergo what scientists call “phase change.” As part of the shift in behaviors associated with phase change, locusts can become gregarious — they group together and form massive swarms as they move across the landscape. It is no surprise then that locust scientists themselves are gregarious, in that effective management of locusts requires coordinated efforts from many different individuals, teams and organizations.

These coordinated efforts, which are essential to effective preventative locust management, are in part the theme of a recent webinar (in Spanish) presented by Cyril Piou of France’s Agricultural Research Center for International Development (CIRAD). Piou holds a PhD from Bremen University in Germany, and since 2010 he has worked as part of the Acridology Team at CIRAD, researching various themes in population dynamics, ecology, and modeling systems. Due to his experience in these areas, Piou frequently collaborates with other locust researchers, including partners through Argentina’s National Institute of Agricultural Technology (INTA), who hosted the webinar.
