The western tarnished plant bug (Lygus hesperus Knight) (Hemiptera: Miridae) is a polyphagous pest of numerous western crops. This pest overwinters in a relatively short duration adult diapause, but many details regarding diapause induction and maintenance remain unstudied. Instar-specific responses to a switch from short (10-h) to long (14-h) days, long to short days, and a temporary (4-d) swi...

(Photo: Boris Hrasovec, Faculty of Forestry, Bugwood.org) The IAEA’s support to Member States in the field of insect pest control has mainly focused on the Sterile Insect Technique (SIT), which is a type of insect birth control, where mass reared and systematically released sterile males of the target pest insect mate with wi...

BACKGROUND RNA interference (RNAi) induced through double stranded RNA (dsRNA) has been used widely to study gene function in insects. Recently, it has been reported that gene knockdown in several insects can be induced successfully through feeding with dsRNA. However, it is still unknown whether phenotypic silencing of genes not expressed in the midgut occurs after ingestion of insect dsRNA. ...

Stored product insects feed on grains and processed commodities manufactured from grain post-harvest, reducing the nutritional value and contaminating food. Currently, the main defense against stored product insect pests is the pesticide fumigant phosphine. Phosphine is highly toxic to all animals, but is the most effective and economical control method, and thus is used extensively worldwide. ...

Western flower thrips (WFT) is one of the most economically important pest insects of many crops worldwide. Recent EU legislation has caused a dramatic shift in pest management strategies, pushing for tactics that are less reliable on chemicals. The development of alternative strategies is therefore an issue of increasing urgency. This paper reviews the main control tactics in integrated pest m...

Purpose: Sticky traps are effective for monitoring and managing insect pests. In addition to pest insects, beneficial insects also caught in sticky traps. Hence, it is necessary use catch selectively. The attraction of different groups coloured was studied as an attempt suppress the populations selectively field. Research Method: traps: yellow, blue, luminous green, white, transparent (control)...
