“…A number of studies have been conducted to investigate the bioecology of Scarabaeoidea under field conditions (Jarvis 1966; Wiener and Capinera 1980; Lumbreras et al 1990; Grunshaw 1992; Kuniata and Young 1992; Vitner 2000; Ansari et al 2006). However, in Brazil, few studies have been conducted on this group of insects (Santos 1992; Silva and Loeck 1996), and no information exists on the biological aspects of the Agaocephalini (Pardo-Locarno and Morón 2006; Oliveira et al 2008; Grossi 2009), which is essential for developing management strategies for A. bolboceridus in Brazil.…”

The white grub, Aegopsis bolboceridus (Thomson) (Coleoptera: Melolonthidae), is an important vegetable and corn pest in central Brazil. The objective of this study was to examine the biology of A. bolboceridus in the field and to update the list of its host plants. The study was conducted in an area with vegetable crops and corn located in the Federal District of Brazil. Samplings were taken to observe the biological stages of A. bolboceridus, preferred oviposition sites, and the adult swarming period. A. bolboceridus exhibited a univoltine cycle that lasted approximately 12 months from egg to active adults. Its eggs were found from October to November. The larval stage lasted approximately eight months, occurring between October and May. Pre-pupae were observed between April and June, and pupae were found between May and July. Inactive adults were observed in July and August, and the swarming period was between September and October. The females preferred to oviposit in sites with taller plants. Four new plant species were identified as hosts for this pest, and two new locations were recorded for its occurrence. This study is the first to describe the biology of a representative of the tribe Agaocephalini in Brazil.

“…However, many species do not follow the 1:1 theoretical proportion as they respond to their changing local environmental conditions ( Hamilton, 1967 ). In Melolonthinae sex-ratio though their flight season can be female-biased ( Méndez-Aguilar et al, 2005 ; Kalleshwaraswamy et al, 2016 ), male-biased ( Ansari et al, 2006 ; Švestka, 2006 ; Švestka, 2010 ) or at a 1:1 ratio ( Harari, Ben-Yakir & Rosen, 1994 ; Méndez-Aguilar et al, 2005 ). However, it is worthwhile noting that sex-ratio can vary between those proportions every day during the flight season ( Švestka, 2006 ; Švestka, 2010 ; Kalleshwaraswamy et al, 2016 ), as shown in this study ( Figs.…”

“…These include Schizonyza ruficollis (F.) ( Kulkarni et al, 2007 ) and Holotrichia spp. ( Kulkarni et al, 2009 ) in India, Hoplia philanthus (Füessly) in Belgium ( Ansari et al, 2006 ), and Phyllophaga cuyabana (Moser) in Brazil ( Oliveira & García, 2003 ). However, dramatic defoliation can also occur.…”

BackgroundMelolonthinae beetles, comprising different white grub species, are a globally-distributed pest group. Their larvae feed on roots of several crop and forestry species, and adults can cause severe defoliation. In New Zealand, the endemic scarab pest Costelytra zealandica (White) causes severe defoliation on different horticultural crops, including grape vines (Vitis vinifera). Understanding flight and landing behaviours of this pest can help inform pest management decisions.MethodsAdult beetles were counted and then removed from 96 grape vine plants from 21:30 until 23:00 h, every day from October 26 until December 2, during 2014 and 2015. Also, adults were removed from the grape vine foliage at dusk 5, 10, 15, 20 and 25 min after flight started on 2015. Statistical analyses were performed using generalised linear models with a beta-binomial distribution to analyse proportions and with a negative binomial distribution for beetle abundance.ResultsBy analysing C. zealandica sex ratios during its entire flight season, it is clear that the proportion of males is higher at the beginning of the season, gradually declining towards its end. When adults were successively removed from the grape vines at 5-min intervals after flight activity begun, the mean proportion of males ranged from 6–28%. The male proportion suggests males were attracted to females that had already landed on grape vines, probably through pheromone release.DiscussionThe seasonal and daily changes in adult C. zealandica sex ratio throughout its flight season are presented for the first time. Although seasonal changes in sex ratio have been reported for other melolonthines, changes during their daily flight activity have not been analysed so far. Sex-ratio changes can have important consequences for the management of this pest species, and possibly for other melolonthines, as it has been previously suggested that C. zealandica females land on plants that produce a silhouette against the sky. Therefore, long-term management might evaluate the effect of different plant heights and architecture on female melolonthine landing patterns, with consequences for male distribution, and subsequently overall damage within horticultural areas.

“…Firstly, the short period between emergence of IJs from the cadavers and the evaluation may not have allowed for a full expression of mortality. Secondly, as the field trial was undertaken under very hot conditions, H. philanthus larvae may have migrated downwards in the soil to avoid the heat,14 thereby escaping potential exposure to IJs. The present results corroborate the findings of Ansari et al 13 who also reported low grub mortality at 2 WAT when aqueous suspensions of EPNs were applied, but mortality significantly increased in both greenhouse and under field trials (>90% and >60% respectively) 6 weeks and 1 year after EPN application 21.…”

“…The specific objectives of the current study were (i) to formulate EPN‐killed insect cadavers in various carrier/coating materials, (ii) to determine effects of storage temperature on EPN survival in the cadaver, (iii) to assess emergence and virulence of IJs from formulated and non‐formulated cadavers, (iv) to determine the horizontal dispersal of IJs from infected cadavers and (v) to determine the efficacy of formulated cadavers against native white grubs, Hoplia philanthus Füessly (Coleoptera: Scarabaeidae) under greenhouse and in field conditions. Hoplia philanthus was used as the target host insect owing to its availability throughout the year and its importance as a pest of pasture and turfgrass 13, 14…”
