Periplaneta Australasiae

The effect of temperature on the development of the 1<SUP>st</SUP> instar of <I>Periplaneta australasiae</I> (Fabr.) was studied at the four constant temperatures of 21°C, 24°C, 27°C and 30°C in temperature-controlled chambers. Mortality was 50% at 30°C, and 10% at 21°C, 24° and 27°C. Thermal constants were established by plotting linear regression to development rate. The thermal threshold for the development was 17.1°C and the thermal constant for 1<SUP>st</SUP> instar larvae was 147.1 day-degrees. As “safe temperature” (<I>t<SUB>s</SUB></I>) – the temperature to be maintained in stores or food premises to prevent the development of a pest species – we recommend 16°C.

Development Rates

Temperature has a significant influence on development rates of insects and mites. Many parametric models were built to describe the temperature-dependent development rates. However, these models provided different shapes of the curves of development rate versus temperature. For different datasets, investigators have to spend much time on considering which the parametric model is the best for describing the temperature-dependent development rates. In the present study, we encourage investigators to use an important non-parametric model, the loess method, which belongs to local regression methods. The loesS method is used to fit some published data on the development rate of aphids to check the goodness-of-fit. We find that the loess method is very flexible for fitting the given datasets. Thus, we consider that the loess method can be used to describe the effect of temperature on the development rate of insects or mites.

The development of individual cotton bollworm stages depending on the ambient temperature was studied in laboratory conditions. The effect of temperature on the development of all stages of <I style="mso-bidi-font-style: normal">Helicoverpa armigera</I> was studied at three constant temperatures of 20, 25, and 30°C in temperature-controlled chambers. The temperature dependence of the developmental rates and the thermal thresholds were established by means of linear regression. Our data has established following optimal temperatures: the lower thermal threshold for the development of&nbsp;the <I style="mso-bidi-font-style: normal">Helicoverpa armigera</I> eggs is 14.83°C, for the development of&nbsp;the larvae is 11.34°C and for the development of&nbsp;the pupae is 8.18°C. The termal constant for the development of&nbsp;the <I style="mso-bidi-font-style: normal">Helicoverpa armigera</I> eggs is 64.10 day-degrees, for the development of&nbsp;the larvae is 344.83 day-degrees and for the development of&nbsp;the pupae is 222.22 day-degrees. The lower thermal threshold for the total <I style="mso-bidi-font-style: normal">Helicoverpa armigera </I>development is 11.50�C and the thermal constant is 625.00 day-degrees.

AbstractThe temperature-dependent development of Apanteles hemara (Nixon), a larval endoparasitoid of the devastating amaranth pest Spoladea recurvalis (F.) was studied in the laboratory at six constant temperatures (10, 15, 20, 25, 30 and 35 °C), a photoperiod of 12L:12D and a relative humidity of 60–70%. Developmental time decreased significantly with increasing temperature within the range of 15–30 °C. The parasitoid's pupal mortality, successful parasitism rate, adult emergence rate and longevity, sex ratio and fecundity were affected by temperature. The population of A. hemara failed to develop at 10 and 35 °C. The development threshold (Tmin) and the thermal constant (K) were calculated by the linear model while the lethal temperature (Tmax) was determined by the Lactin-1 model. The estimated values of Tmin, Tmax and K by the two models were 10.3 °C, 35.0 °C and 185.18 DD respectively for the total immature development. The estimated value of the optimum temperature using the Taylor model was 30.8 °C. This is the first study to report on the effect of temperature on the developmental parameters of A. hemara giving an insight into its biology. The implications of these findings for the use of A. hemara in biological control are discussed.

Response To Temperature

The predatory gall midge, Feltiella acarisuga (Vallot) (Diptera: Cecidomyiidae), is an acarivorous species that mainly feeds on spider mites (Acarina: Tetranychidae). Because of its cosmopolitan distribution and predation efficacy, it is considered an important natural enemy available as a biological agent for augmentative biocontrol. However, despite its practical use, the thermal development and survival response to temperature have not yet been fully studied. In this study, we investigated the stage-specific development and survival of F. acarisuga at seven temperatures (11.5, 15.7, 19.8, 23.4, 27.7, 31.9, and 35.4 °C) to examine the effect of temperature on its lifecycle. All developmental stages could develop at 11.5–31.9 °C, but the performance was different according to the temperature. From the linear development rate models, the lower development threshold and thermal constant of the total immature stage were estimated at 8.2 °C and 200 DD, respectively. The potential optimal and upper threshold temperatures for the total immature stage were estimated as 29.3 and 35.1 °C using a non-linear development model. The operative thermal ranges for development and survival at 80% of the maximum rate were 24.5–32.3 and 14.7–28.7 °C, respectively. Thus, it was suggested that 24.5–28.7 °C was suitable for the total immature stage. In contrast, conditions around 8 °C and 35 °C should be avoided due to the lower development rate and high mortality. Our findings provide fundamental information for an effective mass-rearing and releasing program of F. acarisuga in an augmentative biocontrol program and help to predict phenology.

The present study focused on developing the scenario of the room temperature effect on the development of two distinct butterfly species, Danaus chrysippus and Junonia iphita . Temperature required for development of final instar larvae of D . chrysippus (25.9°C) was much higher than J. iphita (19.09°C); whereas in contrast to that in prepupation stages J. iphita (8.21°C) acquired at much higher temperature than D . chrysippus (7.93°C). In case of chrysalis stages D . chrysippus required much higher temperature in comparison to J. iphita (26.8°C). In the study the pupation stages is merged with the chrysalis stage. The completion of chrysalis stages was much lower in D . chrysippus (average 03 days) than J. iphita (average 6.25 days). The present study furnished that development rate was greatly accelerated with thermal threshold roaming around room temperature. However in D . chrysippus thermal threshold scenario stands static as in the present study all the specimens were reported dead in the cocoon stages providing a keynote information about the temperature manipulation on two distinct species which can be utilized as grass root level for successful conservation management.
