During this time, the use of biological insecticides has increased from less than 5% to around 50% of the overall Swiss agricultural market. On a worldwide level, the relevant figures were and still are much lower. A lot remains to be done!

MARTIN ANDERMATT AND ISABEL ANDERMATT, ANDERMATT BIOCONTROL

The beginnings Full of youthful drive, we decided to launch a codling moth granulovirus in 1986. Literature provided information concerning production, effectiveness in the field, as well as toxicological data. In January 1987, we submitted a modest registration dossier, then we produced the first batches in our apartment, and, in summer we carried out a few field studies. By December 1987, a provisional authorisation was issued for our codling moth granulovirus product MADEX®. This was the first registration worldwide of a granulovirus product for use in food production. Due to considerable interest of organic Picture 1: Isabel and Martin Andermatt fruit growers in our new product, we decided to move from Oberglatt (Can- ton Zürich) to Grossdietwil (Canton Lucerne) at the end of 1988, where we were able to rent an old farmhouse growth for such a long time.

Picture 2: Company building of the Andermatt Group 5 In 1996 the important registrations for mating disruption in wine- and fruit- growing were obtained, which marked the beginning of an impressive success story far beyond organic farming. Our own research and development department developed several dozen products, including the internationally acclaimed MADEX PLUS for the control of granulovirus-resistant codling moths. Moreover, our success story has resulted in numerous regional and national prizes and awards.

Current situation The Andermatt group employs around 100 people at home and abroad. It is by far the biggest employer in the municipality of Grossdietwil. Andermatt Biocontrol offers the broadest range of insect virus-products worldwide, selling them in more than 30 countries. After acquiring the Picture 3: Our first small photovoltaic system, built in 2008, was extended to 500 m² in 2012. company Topcat GmbH, the market of rodent control was developed with great success.

Bacillus amyloliquefaciens FZB42 is a naturally occurring soil bacterium promoting plant vitality and performance through its versatile properties. Andermatt Biocontrol is the new and exclusive worldwide distributor of Bacillus amyloliquefaciens products such as RHIZOVITAL 42, manufactured by ABiTEP GmbH in Berlin.

Success in controlling Spodoptera littoralis thanks to LITTOVIR The larvicide LITTOVIR®, which is based on an insect pathogen virus formulation, opens new possibilities in biological and integrated plant protection in vegetable production as well as general agriculture. Due to its residue-free and highly selective mode of action, LITTOVIR facilitates increased flexibility in the strategy of Spodoptera littoralis control.

IRIS KRAAZ, ANDERMATT BIOCONTROL

The African cotton leafworm (Spo- doptera littoralis) is found mainly in Africa, in the Middle East and in the Mediterranean area, where it is the cause of considerable yield loss for crops such as bell pepper, tomatoes, leafy vegetables, strawberries and cotton. Being an extremely polyphagous species, it is able to attack more than 80 different plant types. Picture 1: The larvae prefer to feed on young leaves of the plants. However, they also attack The active ingredient of LITTOVIR, young shoots, stalks, leaves and fruit.

SALES OF TOPSNAP-TRAP

The TOPSNAP-trap has been available since August 2012 and can be obtained via resellers or directly from Andermatt Biocontrol. The sales network – currently consisting of resellers in Switzerland and Germany – is being gradually expanded and extended. More information about the TOPSNAP-trap is available on www.topcat.ch.

In both cases, the natural insecticide DELFIN® has shown a very good effect, in this experiment, even better than the chemical-based insecticide Lambda-cyhalothrin.

At most vegetable farms the effect of the new method returned better results than the strategy used previously (e.g. “open breeding”). Poor results were obtained when application started too late i.e only a few weeks after the start of cultivation, or if ants had been able to remove the beneficial insects out of the capsule. It still has to be checked whether a combination of the parasitoid mixture with aphid predators would be of use when infestation is high. Also, better protection of the capsules Picture 1: Capsule containing feed for hatching aphid parasitoids. against ants is desirable. Quantities to be used: 1 capsule per 200 m².

Biological alternatives for the control of rumex are hard to find. Within the framework of a CTI- project, in which Andermatt Biocontrol is also involved, a new and promising method of controlling this weed is now undergoing tests.

Granulovirus is still the first choice for codling moth control! New chemical active ingredients such as chlorantraniliprole and emamectine are currently the fruit growers’ first choice for the control of the codling moth. But to ensure efficient long-term control of the codling moth and to minimise residue, it is imperative that codling moth granulovirus deployment retains its place in the control strategy.

Bees and Varroa: Approach for Integrated Treatment The warm and dry spring of 2011 promoted not only a good honey harvest but also optimal breeding conditions for varroa mites. Many seemingly strong colonies collapsed during the following winter. Beekeepers also reported losses of nuclei. Has varroa treatment lost its efficacy? The search for explanations proved to be rather complicated.

Red poultry mites in chicken pens: counteractive measures compliant with organic standards In poultry pens, the red poultry mite (dermanyssus gallinae) is a major problem. Warm temperatures during summertime are followed by a huge increase with a consequent negative influence on the well-being of the animals. Strategic control and appropriate measures keep the population below a harmful limit.

New business field of Entomos AG: training and courses The Entomos AG is the youngest sister company of Andermatt Holding AG. It offers entomological products and services to markets outside of the agricultural sector. Previously, the company has been active in three business segments. It supplies feed insects to the zoological field, research insects for entomological research centres and medical maggots for the treatment of chronic wounds. Entomos AG now also offers entomological courses, seminars and services.

This means that many questions about climate, hygiene and reproductive rate, etc. remain unanswered for insect fans. Also, the high expense involved in setting up and maintaining a breeding farm is a problem for many hobby breeders. At Entomos AG we receive inquiries on how to hold and breed feeding and other insects on a daily basis. The newly developed courses offer tips and tricks for building and organ- ising such insect breeding stations for interest parties. Participants learn how they can breed high quality insects in their own home with little effort. We convey our vast knowledge, accu- mulated in the last 25 years at the Andermatt group of companies to both hobby breeders and professional insect keepers.

OPTIMAL INFRASTRUCTURE

The facilities at the site of the Andermatt Group are optimally equipped for seminars from 5 to 30 people. Depending on demand, seminars are also held at external locations and even at customers’ premises.
