바이러스, 곰팡이 또는 기생충을 기반으로 한 생물학적 방제제에 대한 진전도 있었습니다.
여기에는 최근 케냐에서 허가된 Fawligen이라는 바쿨로바이러스 생물농약이 포함됩니다.
Rwomushana는 이 바이러스 기반 살충제의 장점은 농부들이 감염이 시작될 때 제품을 구
입하여 사용할 수 있다는 것이라고 말했습니다. 그런 다음 죽은 애벌레를 모아서 물로 분쇄
함으로써 농부들은 저렴한 비용으로 바이러스가 포함된 스프레이를 직접 만들 수 있습니다.
이 바이러스는 특히 열대거세미나방을 감염시키므로 더 큰 위험을 초래하지는 않습니다.
열대거세미나방은 분명 무시해서는 안 될 심각한 문제이지만 이것이 유일한 문제는 아닙니

Agroecological solutions better than pesticides in fighting fall armyworm, experts say
29 February 2024
Fall armyworm (Spodoptera frugiperda) is an invasive agricultural pest, which first hit West Africa in
2016 and quickly spread across the continent.
Experts have now found that the pest’s impact on maize yields is no longer as severe as initially
feared. An integrated pest management approach, prioritizing nontoxic control measures, is the best
way to tackle the infestation, improve yields and protect human health, according to experts.
In 2016, an infestation of fall armyworms hit a vast swath of Africa, alarming farmers and
governments. Eight years on, experts say that crop losses from the agricultural pest are less severe
than initially feared. A key lesson learned is that an agroecological approach to pest control ? and
not the indiscriminate use of pesticides ? is the best option for limiting damage, according to a
recent guide by the Center for Tropical Forest Research and World Agroforestry (CIFOR-ICRAF).
A type of moth, the fall armyworm (Spodoptera frugiperda) came from the Americas and feeds on a
wide variety of crops, including maize and rice. Populations can swell and spread incredibly quickly:
female moths lay more than 1,500 eggs during their three-week life span, and a single moth can fly
more than 100 kilometers (60 miles) in a single day. Fall armyworms arrived in West Africa in 2016,
then spread quickly throughout the sub-Saharan region and into the Middle East, Asia and Australia.
In Africa, fall armyworm mostly endangers maize, a staple for many smallholder farmers. The first signs
of an infestation are transparent patches on young leaves. As the plant grows, the developing
caterpillars move inside the whorls, excreting a yellow-brown frass as they feed. Eventually they attack
the maize ear.
Initially, many governments spent millions on pesticides to stave off disaster. But these pesticides were
often highly toxic, not specifically formulated for fall armyworm, and often applied at incorrect dosages
or without protective equipment, thus endangering both ecosystems and human health.
However, more recent research shows that the infestation wasn’t as catastrophic as was initially feared.
A two-year field study across 12 landscapes in Zambia and Malawi found that when pesticides weren’t
