Ladybirds enjoy a cotton aphid buffet

The minute two-spotted lady­bird bee­tle (Diomus notescens) and the trans­verse lady­bird bee­tle (Coc­cinella trans­ver­salis) are two nat­ural ene­mies of cot­ton aphid (Aphid gossypii). They are com­monly found in Aus­tralian crops, how­ever rel­a­tively lit­tle is known about their biol­ogy. A series of lab­o­ra­tory exper­i­ments were con­ducted by the Queens­land Depart­ment of Agri­cul­ture and Fish­eries (DAF) to learn more about aspects of… Read more »

Effective aeration cooling of stored grain

Philip Burrill   April 26, 2016   Comments Off on Effective aeration cooling of stored grain

Aer­a­tion cool­ing uses fans on grain stor­ages to lower grain tem­per­a­tures, which helps main­tain grain qual­ity and reduce stor­age pest prob­lems. When cool­ing grain using aer­a­tion, the aim is to reduce and keep grain tem­per­a­tures below the fol­low­ing sea­sonal tar­gets: Win­ter crops (stored November-March): below 23°C Sum­mer crops (stored April-September): below 15°C Most insect stor­age pests pre­fer tem­per­a­tures from 25–35°C (peak breed­ing… Read more »

Bean podborer on the move in mungbeans

Hugh Brier   March 22, 2016   Comments Off on Bean podborer on the move in mungbeans

Bean pod­borer (Maruca vit­rata) have been observed in large num­bers (>20/m2) in flowering/podding mung­beans planted from Jan­u­ary onwards in the Bur­nett region. They are likely to be present in other coastal/subcoastal regions such as the Bur­dekin, Cal­lide Val­ley and the Wide Bay/Burnett (par­tic­u­larly in late-planted crops), and to a lesser extent in the east­ern Dar­ling Downs, and Emer­ald in Cen­tral… Read more »
