“…Their insecticidal activity is based on their mode of action as interfering with larval growth and development, growth retardation, molting inhibition, or induction of malformation in the larval stage. In the adult insect, these extracts inhibit egg maturation and may also induce sterilization in several insect species and such effects can also be induced as hormone application [6,7].…”

Nanotechnology is considered to be a development way to gain efficient and potential approaches towards pest control. The effect of both neem and peppermint oils as bulk, nano and loaded nano-emulsions have been studied against the different biological aspects of the 2 nd larval instar of Agrotis ipsilon (Hufn.) under laboratory conditions. Their effects on enzymatic activities were investigated for the 2 nd and 4 th larval instars. The effects of adding the different formulations of either neem or peppermint oils to artificial diet of 2 nd instar larvae show significant elongation of the larval duration; percentage mortalities were increased as well as larval malformations. It was recorded that nano-formulations (emulsion or loaded) significantly decreased the pupal weight and significantly increased the pupal duration, percentage pupal mortalities and pupal malformation. Adult longevity show insignificant effect, while female fecundity and percentage egg fertility show significant decrease in comparison with the control. Results of enzymatic activities show marked effects of the three formulations of either neem or peppermint oil. Significant inhibitions were recorded for amylase, invertase, trehalase, protease and alkaline phosphatase. However, significant increase in the activities of cuticle phenoloxidase and chitinase were recorded. Marked variations were recorded between nano-formulations and the bulk form.

“…Herbivorous insects can be highly destructive and cause significant crop loss (Zepa-Coradini et al 2010;Dimetry et al 2013). While damage caused by herbivorous insects is recognizable, seemingly harmless insects can play a hidden role as vectors of plant pathogens (Dennis 1978;Harris et al 1996;Jarvis et al 1993;Konam and Guest 2004;Cloyd and Zaborski 2004;Elmer 2008).…”

The options for managing Fusarium wilt in greenhouse cucumbers are limited by our poor understanding of the modes of survival and dissemination of the pathogen. This study uses a specific quantitative realtime PCR assay for Fusarium oxysporum f. sp. cucumerinum to investigate the significance of flying insects as aerial vectors of the pathogen in a commercial cucumber greenhouse. Shore flies were more frequently detected (35.5%) carrying F. oxysporum f. sp. cucumerinum than sciarids (25%), with both species carrying between 1 9 10 2 and 1 9 10 6

Watermelon, Citrullus lanatus is one of the most widely grown fruit crops in all parts of India. The cotton aphid, Aphis gossypii Glover was found to be the most destructive pest of watermelon in the early stage of crop growth. The aphid secretion of honeydew and development of sooty mould prevent the photosynthetic activity of leaves causing 45-75 % of seedling mortality. In this context, a field experiment was conducted to evaluate certain biorational pesticide against A. gossypii in watermelon. It was found that a significantly lowernumber of A. gossypii population (4.39 aphid/leaf) was recorded with the treatment of Azadirachta indica oil @ 3% followed by Beauveria bassiana (1x108 cfu spores @ 8 g /L) (6.01 aphid/leaf) and spinosad 45% SC @ 0.3mL/L (9.16 aphid/leaf), respectively resulting 92.89%, 90.27% and 85.17% reduction of A. gossypii population. Similarly, with the same trend the highest fruit yield (25.50 t ha-1) was recorded in the treatment of A. indica followed B. bassiana (24.43 t ha-1), spinosad (23.53 t ha-1) and lowest in the untreated check (16.30 t ha-1). The increase in fruit yield (56.44%) was recorded in the treatment of A. indica followed B. bassiana, (49.87%) and spinosad (44.17%). A maximum incremental benefit cost ratio of 1:2.84 was recorded in the treatment of A. indica followed by B. bassiana (1:2.74) and spinosad (1:2.68). From these findings it may be recommended that three rounds of application of A. indica oil @ 3% or B. bassiana (1x108cfu spores @8g /L) or spinosad 45% SC@ 0.3 mL/L at 15 days interval for the management of A. gossypii in watermelon
