“…Soil treatment with liquid insecticide application was efficient and greatly impacted the LMW population. This find corroborates previous studies where the LMW reinfestation at 40 days after soil treatment with chemical insecticide was low (10-20%) (SANTOS et al, 2009;ALVES et al, 2010).…”

“…Although the pulverization of insecticides on litter is very common; it can reach a small number of the insects which are more superficially located without reaching larvae and pupae, which are in the soil, leading to poultry house reinfestation (DIAS et al, 2013). On the other hand, liquid application of chemical insecticides on the soil and walls before the distribution of the litter for a new flock are efficient and cause a significant reduction of LMW populations (SANTOS et al, 2009;ALVES et al, 2010). The soil treatment with a formulation of Beauveria bassiana Unioeste 4 fungus conidia (1000 L, 1 × 10 9 conidia•mL -1 ) was also efficient, maintaining the LMW population at low levels for 5 months after treatment (ALVES et al, 2015).…”

Liquid preparation of diatomaceous earth against the lesser mealworm, Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae)

The lesser mealworm (LMW) is the most important pest in poultry production. Insects are associated to avian pathogens, mainly Salmonella. Its control is based on chemical insecticide, with limited efficacy in population reduction. Also, insect populations are resistant to the main active ingredients used. Diatomaceous earth (DE) is a mineral dust that has activity against the LMW when used in dust application. No information is available about DE liquid preparation against this insect. Thus, bioassays were conducted aiming to develop a strategy for DE liquid preparation to this insect control. In laboratory the ideal concentration for poultry house experiment was estimated and the effect of insect contact with poultry litter or chicken feed after application was checked. In the poultry house, DE liquid preparation (10% in water, 1 L•m -2 ) was applied on the dirt soil of a cleaned and empty poultry house. In the control poultry house, a chemical insecticide was used (cypermethrin 15 g + chlorpyriphos 25 g + piperonyl butoxide 15 g) (1 L•m -2 ). DE at all concentrations was efficient mainly when insects were dried for 24 h before contact with a substrate. In poultry house, both treatments obtained similar results at 15 days after treatment (94% of reduction of insect population). At 45 days after treatment, the insect population with DE treatment increased 39% while the insect population remained 17% smaller than the initial population with a chemical insecticide. DE liquid preparation has potential to be used as a safe treatment in LMW population management, as a shock treatment.

The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the effect of a new product (cypermethrin-6%) under laboratory and field conditions and assessed its in-vitro compatibility with the fungus Beauveria bassiana (Unioeste 4 isolate). Its efficiency in dry powder and wettable powder formulations was also assessed in the laboratory through comparison with a similar insecticide (cypermethrin-5%) at five different concentrations. The field assays were conducted in two commercial broiler breeder houses (Treated and Control), applying the new product on the litter at the manufacturer's recommended concentration (RC). Germination, vegetative growth, conidial production, number of colony forming units (CFUs) and insecticidal activity of the fungus were used to evaluate the compatibility of the insecticide. The effects of the cypermethrin-6% product and cypermethrin-5% were equivalent in the laboratory, and the new product exhibited better performance at lower concentrations (¼RC, ⅛RC). The strategy applied in the field reduced the insect population in up to 96% after 75 days. Additionally, all concentrations of cypermethrin-6% were compatible with the fungus under the evaluated in-vitro conditions. Therefore, the new product is considered selective for B. bassiana. Further studies are necessary to assess its compatibility under field conditions, consolidating this strategy as a viable alternative for managing this pest.

Activity of powdered methylxanthine applied to poultry litter on adults of Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae)

et al. 2022

One of the pests that most affect and compromise poultry production worldwide is the insect Alphitobius diaperinus, known as the lesser mealworm. This insect is a vector of diseases that compromise not only chicken production but also human health. This study proposes to examine the efficacy and determine the appropriate rate of methylxanthine (MTX), a natural insecticide extracted from cafeine, for the control of an adult population of lesser mealworms in poultry litter. A total of 2,500 adult mealworms were distributed into five treatments in a completely randomized design using 10 replications with 50 insects per replication. The treatments consisted of a control group and four concentrations of MTX (14, 16, 18, and 20 g/m2) spread in plastic boxes containing reused poultry litter and feed, allocated in a broiler shed, to simulate the farm condition. The experimental period was 18 days, and five readings were performed on days 2, 4, 6, 10, and 18. Methylxanthine affected (P<0.05) the mealworms’ cumulative mortality rate, with the groups of insects housed in boxes treated with 16 g /m2 MTX showing the highest cumulative mortality (86.6%) at the end of the experimental period. In conclusion, MTX has insecticidal action on adults of lesser mealworm and can be used on chicken litter to control the population of this insect in poultry sheds. The MTX concentration of 16 g/m2 showed the greatest effectiveness.
