Wild insects could take over the pollinating role of honeybees

Scientists have identified several wild insects that could undertake the crop pollination function of honeybees. By comparing a range of pollinating insects they found three wild species that appear to be as efficient as the honeybee in pollination but may need management to increase their numbers.

Street lighting affects insect biodiversity

Insect communities are permanently changed by the presence of street lighting, according to new research. The authors of the study found that predatory and scavenging insects such as ants and ground beetles were more common under streetlights at all times of day, suggesting that light pollution does not simply attract different types of animals at night.

Insect diversity improves crop pollination

The decline in numbers of wild bees has caused concern regarding falling levels of pollination for important agricultural crops. Researchers have now demonstrated that the diversity of the pollinator community can significantly affect pollination.

Conservation efforts may be paying off for wild plants and insect pollinators

Since the 1990s, rates of biodiversity loss of wild plants and their insect pollinators have slowed down in north-west Europe, according to a recent study. It is likely that conservation activities, such as agri-environmental schemes, have contributed to this improving situation.

Do agri-environmental schemes benefit insect pollinators?

Agri-environmental schemes (AES) do successfully enhance the number and variety of insect pollinators, research suggests. They are particularly effective when implemented in arable landscapes which also contain some semi-natural habitat.

Insect-eating bats save global maize farmers €0.91 billion a year from crop damage

Insect-eating bats are estimated to be worth US$ 1 billion (€0.91 billion) a year to maize farmers around the world, a new study has revealed. Not only do bats reduce crop damage by eating adult corn earworm crop pests, they also suppress fungal infections in maize ears. Bats and their habitats need to be better protected for their ecological and economic contributions, say the study’s authors.

Wildflower planting supports a range of beneficial insects, not only bees

A study of wildflower planting within agri-environment schemes has demonstrated that the practice can support a diverse array of economically beneficial insect species, not just prominent pollinators such as wild bees and hoverflies. The study demonstrates the high conservation potential of wildflower planting within agricultural landscapes and the value of insects outside the traditional focus of conservation efforts.

Flying insects in west German nature reserves suffer decline of more than 76% (1973–2000)

Insect numbers in west German nature reserves have fallen by more than 76% in just 27 years, according to a new study. The fall was even higher in the summer months, with 82% on average fewer insects being recorded. The reasons for this dramatic fall are unclear. The researchers ruled out changes in weather, plant cover and local landscape playing a significant role in the observed decline, but suggest that intensive agriculture and pesticides in fields near to the reserves could be responsible. Whatever the cause, the catastrophic fall in insect numbers will inevitably lead to knock-on effects on ecosystems in the long term, particularly due to their essential role as pollinators and their position in the food web. The researchers say that preserving and protecting insects should now be a priority for conservation policies.

Neonicotinoid and fipronil insecticides harm birds and fish and reduce their food supply

Neonicotinoid and fipronil insecticides have a range of impacts on birds, mammals and fish, a new review of scientific literature has found. A house sparrow would need to eat just one and a half beet seeds treated with a common neonicotinoid to receive a lethal dose, for instance. The insecticides may also have equally important effects on vertebrate wildlife, such as reducing insect prey and hence food supply.

Neonicotinoids: may reduce crop yields by poisoning insects that eat slug pests

Beetles that are helpful to farmers can be poisoned if they feed on slugs that have eaten crops treated with neonicotinoids, a new study reports. The slugs themselves are not harmed by neonicotinoids. In American field trials, researchers found that plots planted with neonicotinoid-treated soybeans contained more slugs, fewer beetle predators and had 5% lower yields. The insecticide may be reducing the beetles’ effectiveness as a natural control of slug pests.

Evaluating the sublethal effects of insecticides for effective integrated pest management

Parasitoid wasps (Trichogramma pretiosum) are increasingly being used as a biological control agent in agriculture. Since insecticides are often applied to the same crops, it is necessary to assess the effects of different insecticides on this insect. However, the majority of studies have focused on evaluating the lethal, but not sublethal, effects of insecticides. A new study has evaluated the sublethal effects on T. pretiosum of nine insecticides commonly used in soybean production in Brazil. Overall, just three of the nine insecticides tested did not appear to have any harmful sublethal effects on T. pretiosum. This study highlights the importance of considering sublethal, as well as lethal, effects when assessing insecticide selectivity.

Environmental persistence of a pathogen used in microbial insect control

We conducted an experimental study of infection, transmission, and persistence of a nucleopolyhedrovirus (NPV) of Douglas-fir tussock moth (Orgyia pseudotsugata) to better understand mechanisms determining the efficacy of the virus when it is used as a microbial control agent. In a field experiment, we quantified infection rates of larvae exposed to either Tussock Moth Biocontrol-1, the strain currently used for control by the U.S. Forest Service, or a wild-type strain isolated from a natural population. We first allowed each pathogen to decay on experimental branches for 0, 1, or 3 days before allowing uninfected larvae to feed on the branches, and then we fit both a generalized linear model and an epidemiological model of virus transmission to the infection data. Longer decay of the NPV resulted in lower infection rates, but evidence that overall virus transmission differed between wild and pesticide isolates of NPV was weak. The short persistence time of the virus suggests that it does not last long on foliage, in turn suggesting that application of TM Biocontrol-1 must be carefully timed to ensure maximum mortality.
