Summary
[edit]DescriptionGreenhouse thrips (Heliothrips haemorrhoidalis).jpg |
English: Adults and nymphs of greenhouse thrips on fruit of lemon variety Eureka. Nymphs produce a globule of fecal fluid at the tip of their abdomen. These globules of fluid increase in size until they fall off and another one begins to form, resulting in a characteristic spotting of the infestation area with black specks of fecal material. The globules serve as deterrents to predators. Greenhouse thrips suck out the contents of epidermal cells on leaves and fruit, including the chlorophyll or pigment, causing cells to turn pale. Affected areas on fruit and leaves take on a dirty, spotted appearance.
This species is parthenogenic (i.e. reproduces without mating), and males are rarely found. Adult females insert eggs into the leaf or fruit surface. |
