“…The population growth rate (PGR) was calculated using the equation PGR = ln(N f /N 0 )/∆T, where N f is the final number of psyllids, N 0 is the initial number of psyllids, and ∆T is the total number of days for the experiment. Solving for PGR results in a rate of population growth similar to that obtained by the intrinsic rate of increase (r m ) Stark et al 1997). Positive values of PGR indicate an increase, PGR = 0 indicates a stable population, and negative PGR values indicate a population decline.…”

A relatively new insecticide chemistry for controlling sucking insects, afidopyropen, was investigated for toxicity against Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae). We evaluated the mortality of D. citri eggs, nymphs, and adults treated with afidopyropen using both laboratory-reared and field populations. We also quantified the effects of sublethal doses of afidopyropen on D. citri feeding, host choice selection, and fecundity. For laboratory susceptible adults, the contact LC 50 , topical application LD 50 , and leaf dip LC 50 were 2.13, 2.00, and 3.08 ng/µL, respectively. For adults collected from a commercially managed citrus grove in Florida, the contact LC 50 , topical application LD 50 , and leaf dip LC 50 were 1.37, 1.92, and 4.89 ng/µL, respectively. Egg hatch was significantly reduced following exposure to afidopyropen at 100 ng/µL. Furthermore, afidopyropen reduced D. citri nymph survival and adult emergence at concentrations ranging between 0.01 and 100 ng/µL. Diaphorina citri adult feeding decreased on citrus leaves treated with afidopyropen in a concentration-dependent manner as measured indirectly by honeydew excretion, and appeared almost completely inhibited after treatment with 10 and 100 ng/µL solutions of afidopyropen. In choice tests, significantly fewer D. citri adults settled on afidopyropen-treated plants than on control plants at 24, 48, and 72 h after release, with no differences in settling between males and females. Afidopyropen reduced the fecundity of D. citri in a concentration-dependent manner. Collectively, the results suggest that afidopyropen could contribute to the integrated management of D. citri and may therefore be useful in rotational programs to improve resistance management.

“…With the aid of a stereomicroscope, the number of eggs laid and the number of dead mites were evaluated 24, 72 and 120 hours later. The mortality parameter considered mites that, with the touch of a brush, presented limited movement, i.e., did not move from its original position (STARK et al, 1997).…”

“…Accurately measuring chronic, low-level effects of chemical exposures on animal populations in laboratory toxicity tests has proven to be very difficult . The problem is compounded by the observation that some species can withstand high mortality with little effect on population growth rate while other species may be more sensitive to chemical stressors than what is indicated by toxicity studies (Stark et al, 1997). Situations involving complex population dynamics, repeated chemical exposures and multiple stresses all interact to hinder the selection of a measurable response or endpoint that best describes potential population impacts, while allowing for extrapolation to other species and ecosystems.…”
