Effectiveness of the compound chlorpyrifos+ cypermethrin+citronellal against Alphitobius diaperinus: laboratory analysis and residue determination in carcasses

Abstract

Effectiveness, biological security and the absence of residues in meat and/or eggs must be considered when recommending options for the control Alphitobius diaperinus in poultry production environments. This research study evaluated the effectiveness of cypermethrin+ chlorpyrifos+citronellal in the control of A. diaperinus, including analysis for the presence of residues of this compound in poultry carcasses (experimental farm). Two studies were carried out under laboratory conditions. One used paper filters a four dilutions of the compound, and the other used a container including with pulverized broiler litter and the compound. The analysis of carcasses for residues was conducted in broilers that raised in a broiler house treated (floor and/or litter) with the compound at a dilution of 1:800. Birds were regularly sacrificed, submitted to necropsy, and liver, muscle and fat fragments were collected. Gas chromatography was used to identify the possible presence of any chemical residue in these samples. High effectiveness rates against A.diaperinus were observed in the two laboratory studies, as well as the absence of residues in the carcasses. This compound, used in the studied concentrations, can be recommended as a valuable alternative for the control and treatment of A. diaperinus

Susceptibility of the Lesser Mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae), From Broiler Farms of Southern Brazil to Insecticides

“…Currently, the insecticides registered for application in poultry facilities in Brazil include pyrethroids and organophosphates that contain the active ingredients cypermethrin and chlorpyrifos, respectively. These insecticides are widely used, isolated or in mixture, in commercial formulated products against A. diaperinus (Silva et al 2007, Oliveira et al 2016. This reduced number of insecticides registered for use against this species favors the evolution of resistance.…”

Comparison between two insecticide application methods in controlling lesser mealworm beetles in commercial broiler housessser mealworm beetles in commercial broiler houses

“…Although SILVA et al (2007) observed 100% of effectiveness rate for chlorpyrifos, cypermethrin, and citronellal insecticide in the laboratory against A. diaperinus larvae and adults, to obtain 100% of effectiveness rate in field routine is not so simple due to the complexity of controlling A. diaperinus (CHERNAKI-LEFFER et al 2007, WOLF et al 2015. Only the use of chemical products is not enough to control the insect infestation, and the answer could be variable, heavily depending on environmental characteristics of the house (CHERNAKI-LEFFER et al 2007).…”

ATIVIDADE INSETICIDA DO SPINOSAD SOBRE Alphitobius diaperinus EM FEZES DE POEDEIRAS COMERCIAIS NATURALMENTE INFESTADAS

“…O controle do Alphitobius diaperinus em ambientes avícolas tem sido realizado com a finalidade de reduzir a população dos besouros, com menor custo, menor risco e maior eficiência (SILVA et al, 2007, VITTORI et al, 2007, MARCOMINI, et al, 2009, WOLF et al, 2015, DEL VALLE et al, 2016. Uma vez estabelecidos nas instalações, tais coleópteros, conhecidos como "cascudinhos", multiplicam-se rapidamente, sendo encontradas elevadas populações em cama de frangos de corte, de matrizes, e em fezes de poedeiras confinadas em gaiolas (ARENA et al, 2020).…”

“…O A. diaperinus tornou-se uma das principais pragas avícolas (SILVA et al, 2007;SOUZA et al, 2009;CHARLIE-SILVA et al, 2019) de grande preocupação sanitária devido os vários prejuízos que podem ocasionar. Podem ser reservatórios de patógenos como Clostridium perfringens, Campilobacter spp., Escherichia, Salmonella e vírus causadores das doenças de Marek, Gumboro e Newcastle (SAFRIT; AXTELL, 1984;BATES et al, 2004;SEGABINAZI et al, 2005;VITTORI et al, 2007;GEHRING et al, 2020).…”
