The lifespan for thrips is approximately 45 days. Larvae go through two molts in four to five days mature and pupate. A complete generation may be completed in about 20 days at 30C but it is lengthened to 80 days when the insects are cultured at 15C.

The adult female and male longevity is approximately 13 days. When the weather is warm the life cycle from egg to adult may be completed in as short a time as 2 weeks. Reproduction is sexual and on average females lay 15 eggs.

Eggs are inserted into leaves. Thrips live about 45 days and those that are born late in summer will go into diapause until the spring so the species can continue to thrive in the following spring. Mated females live nine days.

Adults can live for around 45 days. Generally marijuana thrips live for around 30 days in total. Regarding the life cycle of these thrips eggs are inserted into plant tissues.

The two pupal stages last two to three days. The egg will normally hatch within a couple of days after being laid and the stage that follows Instar I is tiny and wingless. They then go through to or more nymphal stages before becoming adults.

In the thrips life cycle egg-to-adult development takes about 16 days. Monitor for adult and larval thrips as soon as young plants or cuttings are received. What Does Thrip Damage Look Like.

Adults emerge and resume feeding on flowers buds and terminal foliage. The thrips life cycle vary in length from seven to 14 days at fluctuating temperatures between 68-98 degrees F that are common in most greenhouses. Thrips may have many life cycles in a year.

Two larval stages require about 6 days for completion. Thrips can be found in all regions of North America. The thrips life cycle includes a stage called diapause for certain species.

Cannabis thrips take only 19 days to mature from egg to adult. Shortest during of life cycle have been recorded during April about 14 days and longest in December about 23 days.
