Types of biological control: augmentative, conservation and classical
Biological control, also called biocontrol or bioprotection, is a method of pest control using other organisms, natural enemies, pathogens, semiochemicals and natural substances. Unlike some other methods of control in agriculture, bioprotection often has little to no side effects.
Parasitic wasps play pivotal role in Kenya’s papaya mealybug control
Papaya mealybug (Paracoccus marginatus) is a devastating papaya pest. It impacts many countries in East and West Africa. Infestations can result in significant economic losses, posing a threat to the livelihoods of smallholder farmers. On average, the pest can cause anywhere from 53% to 100% crop losses, costing £2,224 per hectare annually. Its impact on…
Successful on-farm trials using Metarhizium rileyi in Zambia
The fall armyworm (Spodoptera frugiperda) has wreaked havoc on Zambia’s agriculture, devastating smallholder farmers with staggering losses. But amidst the struggle, a promising solution emerges. Through activities on the PlantwisePlus programme and the Village-based biocontrol of fall armyworm in Zambia project, funded by ACIAR, CABI has delved into combating this agricultural menace with various biological…
Trichogramma mass rearing facilities piloted in Pakistan
Championing sustainable agriculture by promoting lower-risk plant protection solutions to tackle crop health challenges is a key objective of CABI’s PlantwisePlus programme. In particular, the managing of plant pests and diseases. A cornerstone of this work is setting up local facilities for the mass rearing of lower-risk plant protection solutions.
Kenyan farmer perceptions of biological control of papaya mealybug
The papaya mealybug problem in Kenya The invasive papaya mealybug (Paracoccus marginatus) is a devastating pest to many crops, with a host range of over 200 plants. The species was first detected in Africa in 2010 in Ghana and then in 2016 in Mombasa County in Kenya. In Kenya, where horticulture makes up 60% of…
Biocontrol agent released to safeguard crops from parthenium weed in Pakistan
Invasive plants can be extremely harmful to crops. “Famine weed” or parthenium is one such plant. Native to tropical America, it was accidentally introduced to several countries. In Pakistan, the weed now covers thousands of hectares of agricultural and rangeland. And it poses an economic burden to farmers.
Controlling the papaya mealybug pest – progress made in coastal Kenya
An initiative to combat the destructive papaya mealybug in Kenya is reaping rewards. A natural predator – a parasitic wasp – has been introduced to coastal counties to help control the pest. This tiny wasp is helping to prevent the damage caused by the mealybug. It’s not only helping to save papaya farms. It’s safeguarding…
Integrated Pest Management upskilling initiative benefits wider community in Nakuru, Kenya
Integrated Pest Management (IPM) is one of the tools for low-pesticide-input pest management. In the heart of Kenya’s Nakuru County, a PlantwisePlus initiative is underway. It aims to upskill and support women and young people to initiate agribusinesses that champion low-risk pest control products and practices. These micro-businesses provide employment for the trainees, while farmers…
New biocontrol agent production model to fight fall armyworm in Bangladesh
The state of BCA use in Bangladesh The use of biological control agents (BCAs) to manage pests is a concept not yet fully embraced by farmers. This is especially true in Bangladesh, where the invasive pest, fall armyworm (Spodoptera frugiperda), has affected many crops. First seen in Bangladesh in November 2018, fall armyworm causes harvest…
Overcoming gender barriers to tomato farming in Pakistan
Tomato is an important crop in Pakistan – every year, the country produces 4.2 million tonnes of tomatoes. Growing them can be labour intensive. But research shows that tomato production has the potential to generate good incomes for rural smallholders. This includes incomes for women farmers. In Pakistan, women account for over 60% of active…
