Optimizing Orius - System release scheme – keeping it simple-minded and price - effectual
“ As part of our uninterrupted intersection improvement program , we recently redesigned the publicity for our popular Orius - System , ” tell Biobest Product Manager Ines de Craecker . “ The new 100 % biodegradable cardboard cartonful carry a gelatin formulation providing a beginning of water for the predatory bugs during transportation . ”
“ Arriving in optimal circumstance , these improvements in overall Orius laevigatus quality have been observed to advance establishment and at long last thrips control in commercial-grade crops . Now , Modern laboratory trials confirm Orius female person with access to this gel newsboy live substantially longer . By provide a weewee source , the gel carrier boosts the survival as well as overall fitness of the adult ( design 1 ) . ”
Artemac to bear out Orius - System in the crop“One of Biobest ’s core goals is to perpetually look for ways to ameliorate current strategy , to make growers ’ work easier , and to keep it uncomplicated , ” says Ines .
Orius is central to effective thrips control strategies in sweet pepper and other crops . Introduced early in the crop as part of prophylactic , inoculative biocontrol , safe piranha establishment is a key element of the overall strategy - with the progeny provide effective control later in the season .
“ To enhance early establishment in the crop , we recommend subsidiary eating , ” says Ines . “ Ephestia kuehniella moth nut are consider the ‘ gold standard ’ intellectual nourishment for Orius . However , their price is a downside . ”
“ To optimize control while protecting growers ’ margins , we urge feeding Orius - System with stock Artemac . substance abuser - friendly offer simpleness , Artemac can also be stack away for foresighted periods and is more cost - efficacious – it offers great note value for money . ”
Empirical evidence suggests growers using Artemac are have excellent predator formation . late laboratory test confirm these findings , with the endurance of Orius adults with access to Artemac 40 % higher than those with no access to this additional nutrient ( material body 1 ) .

In further trial run measuring nut laying , Orius female fed with standard commercial Artemac produced the same number of eggs as those fed with Ephestia ( trope 2 ) .
“ From these termination , we conclude that our more cost - effective standard Artemac is an excellent food source for improving Orius survival during cargo and testis laying for degraded establishment in the field , ” say Ines .

Do n’t release before flower are present in the crop“Sweet pepper flowers add pollen and nectar that are lively for Orius , especially for this ‘ founder ’ coevals of predators , and hence is crucial to the farsighted - term success of the strategy . A fact gestate out in semi - field trial carry out in our Greenlab . In the absence of flower , and hence pollen and nectar , the resultant role showed Orius establishment was reduced by 78 % ( Figure 3 ) . ”

“ In summary , to optimise early Orius - System formation in sweet peppers , the crop should be in flower , and the predators should have access code to our gel bearer during shipment , ” says Ines .
“ Once released , to promote the other establishment and egg laying , the Orius should be fed with Artemac – a cost - effectual alternative to Ephestia . At Biobest , we advocate feeding doubly , at a pace of 500 GB per ha , ab initio at the time of predator release with a second dose of Artemac three weeks later , to support the first generation of Orius nymphs . ”
