“…The intrinsic growth rate ( r ) of 0.067 indicated that the reproduction rate of P. coffea is similar to that of H. hampei (0.067) (Portilla and Streett 2008), much lower than that of C. stephanoderis (0.089), but higher than P. nasuta (0.052) (Portilla et al 2014 and Portilla and Grodowitz 2018). However, unlike those ectoparasitoids, P. coffea does not need to consume immatures of CBB to achieve its reproductive potential.…”

Life fertility tables were constructed for Phymastichus coffea LaSalle, the only known endoparasitoid wasp that attacks the adult female of the coffee berry borer (CBB) Hypothenemus hampei Ferrari. No preoviposition period was observed, and the parasitoid female attacked the CBB females immediately after emergence. The reproductive period was 20.33 (±0.87 SE) h and the postreproductive period of 14.78 (±0.99 SE) h. Mean generation time was 37 d. Median longevity for female and male fed on honey-water solution (50:50) was 35.22 (±1.18 SE) and 17.16 (±0.96 SE) h, respectively. The highest oviposition values were observed during the first 4 h after emergence. The sex ratio (F:M) was 1.11 (±0.31 SE): 1.04 (±0.32 SE) with a finite rate of increase [λ] of 1.06 (±0.002 SE) wasp per days and a rm value of 0.067 (±0.002 SE). Gross fecundity [Mx] and net fecundity [mx] were 19.87 (±1.57 SE) males and females per female and 10.9 (±0.88 SE) females per female, respectively. The net reproductive rate [R0] was 9.49 (±0.75 SE) female per wasp. This study was designed to quantify reproductive rates of P. coffea in CBB females reared on artificial diets and used to improve a mass rearing system for this parasitoid.

“…Life fertility tables were calculated according to Portilla et al (2014) and Portilla and Grodowitz (2018). Portilla et al (2014) explained step by step the calculations of three species of insects and their abridged cohort life table constructions based on formulae and definitions from Carey (1993) and Krebs (2001).…”

“…It is necessary to know the CBB behavior under field conditions, as well as its interactions with climatic factors. Thus, an efficient IPM program integrating several control measures may be implemented (Portilla;Grodowitz, 2018). The previous evaluation carried out immediately before the first spraying of the insecticides revealed that the infestation level found (2.5% -3.5%) was in agreement or slightly higher than the recommended (1.0% -3.0%) to start controlling CBB (Matiello et al, 2020).…”

The coffee berry borer (CBB) Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae) causes significant damage to yield and quality of coffee beans. Cultural measures are important however, chemical and biological control must be adopted within an integrated CBB management system in order to prevent its damage mainly in larger areas. This study aimed to evaluate different doses and times of spray of the chemical insecticide metaflumizone and its association to the entomopathogenic fungus Beauveria bassiana as a tool to the management of CBB in Arabica coffee. The study was carried out in a high dense crop of Arabica coffee cultivar Catuaí Vermelho at 700 m altitude in the highlands of Espírito Santo state, Brazil. The experimental design used was randomized blocks with eleven treatments, four replications and plots of ten plants. Seven evaluations were carried out by sampling the berries in the upper, middle and two sides of the coffee trees. Metaflumizone at a total dose of 3.5 L ha -1 showed high performance for the control of CBB under field conditions in regions of high altitude. The association of metaflumizone with B. bassiana reduced a mean of 88.5% the infestation level of CBB in the post-harvested coffee beans and it can be used as one of the tools for the Integrated Management of CBB under field conditions. Beauveria bassiana can be associated with metaflumizone to control CBB as a complementary spray in March and at a dose of 2.0 kg ha -1 and should be also used in the Integrated Management of CBB. The monitoring of CBB population must be carried out and the first spraying with chemical or biological insecticide must be started at the recommended control level and in the transit season of CBB when flying adults are exposed.

“…For the management of coffee borer, it is necessary to know the bio-ecology of the insect and its interaction with the environment to determine its management, integrating several forms of control (MICHAEL;PORTILLAR, 2018). The application of insecticides is the most widely used method of control and is responsible for the 1940 revolution in insect control, as it has been the most efficient and economical means of combating insects, especially if the objective is to maximize crop productivity in large areas (SOUSA, 2013).…”

The objective of this work was to evaluate the topical, residual and agronomic effects of the insecticides Voliam Targo, Benevia, Lorsban 480 BR, Curbix 200 SC, Sperto, Verismo, Polytrin 400/40 CE, Curyom 550 EC, Polo 500 SC and Vertimec 18 EC in the control of the berry borer of coffee (H. hampei). The experimental design was completely randomized and four replicates were used in the trials. In the laboratory, a direct spray was sprayed on the insect (topical effect) and applied to the fruits of the coffee (residual contamination). In both experiments, each plot consisted of a Petri dish lined with filter paper, 10 fruits in the green stage and 10 adult females of the berry borer, originating from artificial breeding. Two field experiments were carried out at Campus Glória Experimental Farm. The first one was carried out with the objective of evaluating the residual effect of the insecticides on artificial infestation of the berry borer after applying the products to fruits at the beginning of maturation. The number of perforated fruits, dead females, number of eggs and larvae were evaluated in laboratory and field experiments. The second field experiment had as objective to evaluate the effectiveness in controlling the natural population of the berry borer. Two applications were performed with a 30-day interval, using a motorized turbocharger. The number of fruits bored in 50 fruits per plot and percentage of seeds bored in a sample of 250 seeds per replicate were evaluated. In the laboratory, all insecticides provided mortality higher than 80% in topical application and greater than 73% by residual contamination, except the insecticide Polo 500 SC, which provided a 55% mortality. In the field experiment with artificial infestation, all the insecticides differed from the control, maintaining residual control until 30 days after application and with mortality higher than 70%, reaching up to 100% of mortality. In the test with natural berry borer females infestation the insecticides differed from the control in all evaluated parameters, showed efficacy higher than 75% at 35 days after the second application. The insecticides Voliam Targo, Lorsban 480 BR, Curbix 200 SC, Sperto, Polytrin 400/40 CE and Verismo presented the best control results, being indicated for use in the management of the berry borer of coffee.
