Storage and handling
If you have received the packaging of this predatory mite, please release them as soon as possible, because you know biological beneficials have a short life expectancy. Storing them for a long time has a negative influence of their quality. Low temperatures also have a negative influence on Amblyseius swirskii.  BESTmites co. ltd. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions. If necessary, please store them under the conditions described below.

Remarks
Amblyseius swirskii can also develop or maintain its population with pollen of sweet pepper or hairless aubergine. Apply preventive introduction on pollen only from the moment when crop flowers continuously.
 
Advantages
Wide range of preys

Can survive on pollen
Applicable in many crops
 
Biology
The predatory mite Amblyseius (Typhlodromips) swirskii have five developmental stages, egg, larva, pronymph, deutonymph, adult (female or male), respectively. Not susceptible to diapause for Amblyseius swirskii, so it can be use in winter. In addition, it can tolerate high temperature and low humidity due to it originates from the Mediterranean, such as Greece, Turkey, Israeland and Egypt, we can easily find it in nature. So we can explains why Amblyseius swirskii works better at higher the temperatures, but over 20 °C (day temperature) is necessary for its population development. The optimal development temperature is 25-28°C and it can maintain action up to 40°C. Nevertheless under 15°C it is inactive. The critical limit relative humidity is about 70%RH. A significant decrease under this limit does not necessarily mean the end for Amblyseius swirskii due to the micro climate in the field.
Amblyseius swirskii is a polyphagous predatory mite, it can prey on thrips, whitefly, spider mites, tarsonemid mites and pollen, and prefer whitefly and thrips. In optimal conditions, its total life cycle only need 5 to 6 days. Per female will lay about 2 eggs/day when whitefly as prey. Amblyseius swirskii will increase its population very fast and spread among the crop as long as the ideal circumstances. You can find it on the entire plant (nearby the main or lateral veins of leaves or in the flowers), but it has a slight preference for the pollinating crops. To stimulate the spread among the crop, it is recommended to disperse the mites well. The gland hairs on a tomato leaf, honeydew spots and spider webs will obstruct its mobility.
 Although you can easily find it on the leaves, it is very difficult to distinguish Amblyseius swirskii from other predatory mites in the field, such as Amblyseius cucumeris or Amblyseius californicus.
