Toxicities and effects of insecticidal toxic baits to control Drosophila suzukii and Zaprionus indianus (Diptera: Drosophilidae).

BACKGROUND: Drosophila suzukii is a primary insect pest that causes direct damage to fruits with a thin epidermis such as strawberries, cherries and blueberries. In strawberry fields, the co-occurrence of D. suzukii and Zaprionus indianus has increased production losses. This study evaluated the toxicities and effects of insecticidal baits to control adults and larvae of both D. suzukii and Z. indianus . RESULTS: Organophosphate (dimethoate and malathion), spinosyn (spinosad and spinetoram), pyrethroid (lambda-cyhalothrin) and diamide (cyantraniliprole) insecticides exhibited high toxicity to both adults and larvae of D. suzukii and Z. indianus (mortality > 80%) in topical and dip bioassays. However, when the insecticides were mixed with a feeding attractant, a positive effect was observed only for adults of D. suzukii . Insecticides containing neonicotinoids (acetamiprid and thiamethoxam) and pyrolle (chlorfenapyr) caused intermediate mortality to adults of D. suzukii (40?60%) and low mortality for Z. indianus (mortality < 23%); however, these compounds reduced the larval infestation of the two species by 55?86%. Botanical (azadirachtin) and sulphur insecticides exhibited low toxicity (mortality < 40%) on adults and larvae of both species. CONCLUSION: Dimethoate, malathion, spinosad, spinetoram, lambda-cyhalothrin and cyantraniliprole are highly toxic to both larvaeandadultsof D. suzukii and Z.indianus .Theuseoftoxicbaitsforadultsof D. suzukii couldbeanalternativeinmanagement of this species. © 2016 Society of Chemical Industry Keywords: spotted-wing drosophila; fig fly; chemical control; strawberry; toxic bait; pest control.

Controle de Linepithema micans (Hymenoptera: Formicidae) com iscas tóxicas de hidrogel na cultura da videira.

Linepithema micans (Forel, 1908) (Hymenoptera: Formicidae) é a principal formiga associada à dispersão da pérola-da-terra Eurhizococcus brasiliensis (Wille, 1922) (Hemiptera: Margarodidae) na cultura da videira. Uma alternativa para reduzir a infestação da cochonilha nos vinhedos seria o controle da formiga através do emprego de iscas tóxicas. Neste trabalho, foi avaliado o efeito de uma formulação de isca tóxica de hidrogel para o controle de L. micans em laboratório e em vinhedo comercial.

Programa de pesca experimental de atum com vara e isca viva. Moçambique - 1982/1985

An account is given of activities undertaken during the project, which was concerned with the development of tuna fisheries using rod and live bait, in Mozambique. Major tuna species present in the area are described, and fishing gear and methods used outlined, detailing also catch composition and live bait utilized.

Captura de tunídeos com vara e isca viva em Moçambique

Included in the project MONAP GCP-MOZ/006/SWE "Fishing development in inland and coastal waters in Mozambique", a tuna fishing experimental program was carried out in coastal waters of Mozambique, using a catching method with rods and live baits. In order to explore this method and demonstrate the collaboration needed, the present paper has been thought for those interested in an overview of the work to be carried out.
