Israel detects new outbreaks of Diaphorina citri, vector of #HLB 150 kms to the north far from the last season outbreak. They have found the psilid on Murraya paniculata in parks & private gardens. This is a very common ornamental plant in Israel.

What jobs can we do as entomologists? More than you might think. For students looking ahead at potential career paths, learn from this Q&A with five entomologists working in a wide range of positions, from biotechnology to tourism and more. https://t.co/1t049TL1Ci

@esteban_uribe @opcitex @fundecitrus @CitrusBerardo @sci4citrus Not really. Is it a type of soft scale?

[Tim Grout @citrusbugman]

@citrusIPM @gautamsandipa I think thrips are a bit of a special case because they often feed on plants with high levels of terpenoids or other defense compounds so I think they are predisposed to detoxifying chemicals.

First detection in Spain (Huelva) of Scirtothrips aurantii who causes reduction in citrus yields through serious damage to young leaves & reduces the proportion of export-quality fruits.

Paracoccus burnerae is a mealybug without dorsal line, middle size body filaments, ovisac under abdomen, ratio of the last pair of filaments/body<1/2. Penultimate pair of filaments as short as rest. They are laying at the current conditions of 20°C on average, 60 eggs/female.

We report that although oxytetracycline is moved systemically in citrus plants once it is delivered, citrus’ thick, waxy cuticle kept 95% or more out. None of the 9 adjuvants we tested helped in this study. Work with @Killiny_Nabil’s lab. https://t.co/MtfYT0YntR

A revised EPPO dynamic datasheet has just been published for the Asian citrus psyllid Diaphorina citri, one of the vectors of huanglongbing (#HLB)

[Science for Citrus Health @sci4citrus]

Many potentially therapeutic materials for treating #huanglongbing are being investigated.

To test them, Ozgur Batuman of @UF is developing an automated system for delivering chemicals into phloem!

We need to understand how insecticides reach and affect beneficial insects 🐞🐝
In our last paper, we show that pymetrozine and flonicamid, insecticides commonly used in IPM, can kill beneficial insects via honeydew.
