The adult stage can be reached in around 8–15 days; adults can live for around 45 days. [78] Adults have both winged and wingless forms; in the grass thrips Anaphothrips obscurus , for example, the winged form makes up 90% of the population in spring (in temperate zones), while the wingless form makes up 98% of the population late in the ...
The green peach aphid, Myzus persicae, is a vector for more than 110 plant viruses. Cotton aphids (Aphis gossypii) often infect sugarcane, papaya and peanuts with viruses. [21] In plants which produce the phytoestrogen coumestrol, such as alfalfa, damage by aphids is linked with higher concentrations of coumestrol. [117]
Humans have interacted with the Hemiptera for millennia. Some species, including many aphids, are significant agricultural pests, damaging crops by sucking the sap. Others harm humans more directly as vectors of serious viral diseases. The bed bug is a persistent parasite of humans, and some kissing bugs can transmit Chagas disease.
Thrips on plants can spell trouble for gardens, houseplant collections, and greenhouses. But thrips are often overlooked because they are so small and the damage they cause looks similar to that ...
Thrips tabaci is a species of very small insect in the genus Thrips in the order Thysanoptera. It is commonly known as the onion thrips, the potato thrips, the tobacco thrips or the cotton seedling thrips. [1] It is an agricultural pest that can damage crops of onions and other plants, and it can additionally act as a vector for plant viruses.
Just like other species of thrips, their lifecycle consists of egg development, two nymphal stages, a non-feeding propupal stage and pupal stage. [6] A single thrips could produce up to seven generations when living in favourable temperate conditions and more than twelve generations when living in favourable tropical conditions. [ 7 ]
The larvae of Diptera feed on a diverse array of nutrients ; often these are different from those of adults, for instance the larvae of Syrphidae in which family the adults are flower-feeding are saprotrophs, eating decaying plant or animal matter, or insectivores, eating aphids, thrips, and other plant-sucking insects.
Frankliniella schultzei is therefore a species complex, this is important in an agricultural pest because the different species in a complex often have different capacities to damage crops, or transmit viruses (which is true for F. schultzei). Each of the species in a pest species complex has to be investigated separately from the others.
