14th Fumigants & Pheromones Conference - Victoria Falls, Zimbabwe 2020


The Fumigants & Pheromones Conference was started in 1993 in Lubeck, Germany. Its purpose was to gather like-minded companies together under a common cause: Sharing Through Education. Since the first conference in Germany, there have been biennial meetings in Bologna, Valencia, Copenhagen, Thessaloniki, Adelaide, Indianapolis, York, Monterrey, and Bremen. This is the first conference in Africa. We have not only shared a lot in the past 27 years, but we have met lifelong friends. Victoria Falls conference will be no different. We hope you will join us in May 2020!

Cigarette Beetle Pheromone Research and Field Application


Dr. Rizana Mahroof is an Associate Professor in the Department of Biological and Physical Sciences at South Carolina State University. Her major field of research is in entomology with an emphasis in stored product entomology. 


My research is based on developing pest management tactics for stored product Anobiidae, by incorporating various options into a coherent package especially, by determining critical sources of infestation, habitats and breeding sites outside the stored product environment and focusing on reduced-risk innovative pest management strategies. My work further designed to provide a multi-institutional collaboration that allows leveraging skills and expertise of scientists, extension educators and stake holders in addressing the common problem.”

Phosphine Fumigant Resistance

Natural Products Discovery and Utilization


My research efforts focus on solving chemically-based problems in agriculture.  We look at molecules that are produced naturally, as well as, those that are produced by man.

Stored Product Protection in Africa

 “More than 55% of Africans earn their livelihood from agriculture, which is also the key to economic development of the continent. The agriculture is largely traditional and grains constitute the bulk of food production. Sorghum, maize, rice, wheat and millet for cereals and cowpeas, dry beans, groundnut, chickpea and bambara groundnut for pulses, are most common in Africa. Because agricultural production is seasonal while the demands for agricultural commodities are more evenly spread throughout the year, grain storage becomes a particularly important agricultural activity. Grain storage is done on-farm, peasant farmers’ residences (family granaries), community stores and large warehouses. Since most of the grains produced in Africa are destined for human consumption, storage in family granaries predominates. These predispose the grains to serious attacks from biotic constraints such as insects, rodents, birds and micro-organisms. The rate of insect proliferation in these storage structures could be alarmingly high, especially with the warm climate in tropical Africa. Annual grain losses of up to 50% in cereals and 100% in pulses have been reported, although average losses stand at roughly 20%. Major insects that attack cereals and pulses include grain weevils, grain borers, grain beetles and grain moths. Pest prevention, early detection and pest control would greatly reduce grain losses during storage. Control methods comprise physical, chemical and phytochemical measures with emphasis on the use of traditional botanical pesticides.” E. N. Nukenine

Gala Dinner



At each conference since 1993 the delegates from all over the world sing a song from their country. Here the Mexican delegates perform in 2018. This part of the conference has created great memories and expresses national pride.





“Dr. Livingston I presume.” David Livingston, in bronze, looks onto the Zambezi River from the Zambia side of Victoria Falls.


In early November 1855, Livingstone traveled down the Zambezi River to see for himself the area the natives called "smoke that thunders." Approaching the spot in canoes, the party could see the columns of spray and hear the thunderous roar of water miles away from the falls:

A Scene "Gazed Upon by Angels in Their Flight" Livingston                         

"After twenty minutes we came in sight, for the first time, of the columns of vapor appropriately called 'smoke,' rising at a distance of five or six miles, exactly as when large tracts of grass are burned in Africa. Five columns now arose, and, bending in the direction of the wind, they seemed placed against a low ridge covered with trees; the tops of the columns at this distance appeared to mingle with the clouds. They were white below, and higher up became dark, so as to simulate smoke very closely.”
