The development and mortality of the larvae of Aulacophora foveicollis reared on flowers and leaves of Citrullus vulgaris, Cucumis melo, Lagenaria vulgaris, Luffa aegyptica and Momordica charantia, were investigated in the laboratory at 21.5 °C and 52 – 60% relative humidity. Aulacophora foveicollis had four larval instars and its growth curve on L. vulgaris was S-shaped. The number of viable eggs and the survival of the larvae were relatively high on L. vulgaris, C. melo, and C. vulgaris. The larval developmental time was similar and the percentage of malformed adults was low on L. vulgaris and C. melo. The number of viable eggs was the lowest and the newly hatched larvae were unable to survive for more than 3 days on M. charantia.

AbstractAulacophora foveicollisLucas causes economic losses to creeping cucumber [Solena amplexicaulis(Lam.) Gandhi] growers in India and Bangladesh because adults feed on the leaves and flowers causing death of the plant. The insect is a generalist herbivore as it also causes damage to pumpkin, bottle gourd, sponge-gourd and gac fruit production by feeding on leaves and flowers of these plants. At present, insects are controlled with insecticides, which are harmful to human health and the environment. We studied the behavioural responses of adultA. foveicollisto flower surface waxes and synthetic compounds mimicking flower surface waxes to determine their potential for monitoring this pest. The gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detector (GC-FID) analyses ofS. amplexicaulisflower (50 g) surface waxes indicated presence of 17.9 and 3.1 mg alkanes and free fatty acids, respectively. Seventeenn-alkanes fromn-C15ton-C34and 16 free fatty acids from C10:0 to C22:0 were detected in the flower surface waxes. Heptacosane was predominant amongn-alkanes representing 2748.1 µg; whereas, pentadecanoic acid was the major fatty acid accounting for 466.6 µg.Aulacophora foveicolliswere attracted to the flower surface waxes at concentrations of 4 to 8 μg/ml, as demonstrated by a Y-tube olfactometer bioassay. Using a dose response bioassay, the insect was shown to be attracted to individual synthetic pentadecane, heptacosane, nonacosane, undecanoic acid and nonadecanoic acid at 0.70, 0.70, 1.20, 1.60 and 1.40 µg/ml, respectively. The insect displayed highest attraction to a synthetic mixture of 0.70, 1.23, 0.77, 0.84, 0.94 and 0.74 µg/ml of pentadecane, heptacosane, nonacosane, undecanoic acid, lauric acid and nonadecanoic acid, respectively, and hence, this combination might be used for insect pest management such as in baited traps.

Background: Red pumpkin beetle, Aulacophora foveicollis (Coleoptera: Chrysomelidae), is a serious agricultural pest of cucurbit plants. Chemical pesticides have been in practice for many years to control the pests. Recently, the plant essential oils were formulated as nanoemulsion, have gained interest for their effectiveness and eco-friendly nature. The current study was aimed to assess the efficacy of Mentha piperita nanoemulsion against an agricultural pest A. foveicollis. Methods: M. piperita essential oil was analyzed by GC-MS technique. Ulrasonication method was used to formulate the nanoemulsion. The stable nanoemulsion was investigated and characterized by DLS. The efficacy of the nanoemulsion was screened against the pest of cucurbits, A. foveicollis at different concentrations and compared with its own bulk emulsion. Result: In GC-MS technique, menthol was found to be the major component with the highest percentage of 16.47 and the nanoemuslion was prepared in different ratios comprising of peppermint oil, surfactant, acetone and water. The stable nanoemulsion was investigated and characterized by DLS with mean droplet size of 10.84nm, PDI was 0.1 and zeta potential was -45 mv, altogether proves to be the good stability of nanoemulsion. The Bioassay was conducted for about 96 hours and the highest mortality was recorded in the nanoemulsion than the bulk emulsion. The resulted LC50 value of nanoemulsion is 22.38% v/v is found to be effective than the LC50 value of bulk emulsion is 87% v/v, respectively. Thus, from the results obtained the nanoemulsion was found to be highly significance than that of the bulk emulsion. So, nanoemuslion may be used as an eco-friendly agent against the agricultural pest management.

The research was carried out in the field and laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during December, 2011 to October, 2012 on the effect of host and temperature on oviposition and food consumption of red pumpkin beetle (RPB), Aulacophora foveicollis (Lucas). Three cucurbitaceous vegetables viz. sweet gourd (BARI Misti Kumra-1, BARI Misti Kumra-2 and Local Misti Kumra), bitter gourd (BARI Karola-1, Taj Karola-88 and Local Karola) and bottle gourd (BARI Lau-3, BARI Lau -4 and Local Lau) were selected to conduct this research. Host plants had the clear role on the feeding of red pumpkin beetle. Due to feeding of A. foveicollis, the highest percentage of weight loss of leaf was recorded from sweet gourd among the selected cucurbits while Local Misti Kumra was found the most preferred host by beetle considering their feeding efficacy compared to other varieties. Results also showed that temperature had a profound effect on the oviposition and food consumption by A. foveicollis while 30oC was the optimum temperature both for oviposition and food consumption for all selected cucurbits and their varieties.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19099 Progress.
