“…Against subterranean termites (O. obesus), chlorantraniliprole, pyriproxyfen and chlorfenapyr were the most effective insecticides causing 80 -85% mortality of termite workers in 72 h of exposure. These results are consistent with some previous studies showing effectiveness of chlorantraniliprole, chlorfenapyr and pyriproxyfen against different species of subterranean termites (Spomer et al, 2009;Mao et al, 2011;Manzoor et al, 2012;Neoh et al, 2012;Ma and Sui, 2013;Du et al, 2020). Moreover, our study findings substantiate the outcomes of a research work done by Akbar et al (2019) which demonstrated 100% mortality of O. obesus termite workers by chlorantraniliprole, chlorfenapyr and pyriproxyfen within 48 h of exposure.…”

I nsect pests have always been a ubiquitous threat to global food production. These invertebrates cause untold qualitative and quantitative damage to various agricultural and horticultural crops all over the world including India and Pakistan (Arif et al., 2018; Gun-dappa and Shukla, 2018). Almost all field and forage, fruit and vegetable and forest and ornamental crops are attacked by different sucking and chewing insect pests. For instance, mango mealybug (Drosicha mangiferae Green), mango leafhopper (Idioscopus clypealis Lethierry), Asian citrus psyllid (Diaphorina citri Kuwayama) and subterranean termites (Odontotermes Abstract | Contemporary non-target effects of conventional synthetic insecticides necessitate evaluating biorational insecticides owing differential chemistry and modes of action than the conventional ones. This laboratory study comparatively evaluated some selected differential chemistry insecticides against some destructive and economically important insect pests i.e. mango mealybug (Drosicha mangiferae Green), mango leafhopper (Idioscopus clypealis Lethierry), Asian citrus psyllid (Diaphorina citri Kuwayama) and subterranean termites (Odontotermes obesus Rambur). Standard twig-and filter paper-dip bioassay methods were used against sap-feeding pests and termites, respectively. Factorial analyses of variance revealed a significant impact of tested insecticidal formulations and exposure time on the mortality all insect pest individuals. The most effective differential chemistry insecticides against mango leafhopper, citrus psyllids, mango mealybugs and subterranean termites were nitenpyram, clothianidin, thiamethoxam and imidacloprid (causing 74-79% cumulative corrected mortality), thiamethoxam, imidacloprid, clothianidin and spirotetramat (causing 78-85% cumulative mortality), spirotetramat, acetamiprid and thiamethoxam (causing 68-90% cumulative mortality), and chlorantraniliprole, pyriproxyfen and chlorfenapyr (causing 80-85% cumulative mortality), respectively. Overall study findings suggest these above mentioned non-conventional insecticides to be incorporated in the biorational management of these insect pests.

“…Therefore, more response genes are expected to be observed in the thorax + abdomen. Colony response variability was observed in C. formosanus after methoprene treatment 35 , implying gene expression variability at the colony level. Therefore, this may be one reason for more variation in the thorax + abdomen.…”

The soldier caste differentiation is a complex process that is governed by the transcriptional regulation and post-transcriptional regulation. microRNAs (miRNAs) are noncoding RNAs that control a wide range of activities. However, their roles in solider caste differentiation are barely studied. RT-qPCR is a powerful tool to study the function of genes. A reference gene is required for normalization for the the relative quantification method. However, no reference gene is available for miRNA quantification in the study of solider caste differentiation of Coptotermes formosanus Shiraki. In this research, in order to screen the suitable reference genes for the study of the roles of miRNAs in solider caste differentiation, the expression levels of 8 candidate miRNA genes were quantified in the head and thorax + abdomen during soldier differentiation. The qPCR data were analyzed using geNorm, NormFinder, BestKeeper, ΔCt method and RefFinder. The normalization effect of the reference genes was evaluated using the let-7-3p. Our study showed that novel-m0649-3p was the most stable reference gene, while U6 was the least stable reference gene. Our study has selected the most stable reference gene, and has paved the way for functional analysis of miRNAs in solider caste differentiation.
