Determination of Some Biological Parameters Henosepilachna Elaterii Rossi (Coleoptera: Coccinellidae) on Different Watermelon Cultivars

Abstract

Phytophagus coccinellid belong to Epilacchninae sub-family are very different the other coccinellid, and found in tropical and subtropical regions of the world. Henosepilachna elaterii Rossi. feeds on plants of Cucurbitacae family in groups in Europe, Africa and Asia. This pest is found the south Europe, Mediterranean regions, and south of Center Europe. Henosepilachna elaterii is a serious pest of watermelon and cantaloupe, and is a common pest in Aegean region and Southeastern Anatolia Region of Turkey. This species is a vector as different virus disease from health plant to disease plant. This study was carried out to determine biological parameters of Henosepilachna elaterii Rossi. (Coleoptera: Coccinellidae) feeded on watermelon cultivars (Sürme, Galactica, Crimson sweet, Crimson tide and Sugar baby). The trials were made in laboratory conditioned at 16:8 h (day:night) and in 65 ± 5 % relative humidity at 25 ±1 ºC temperature. Data was collected on effect of host plants cultivars on preadult periods. Total development time at prematuring period was shortest at 25 ± 1°C on Crimson tide cultivar as 24.41 days and longest as 25.01 days on Sürme cultivars.

Adult host‐plant preference and larval performance in an oligophagous insect (Chnootriba elaterii)

“…cantalupensis ), because it is a major European crop of a different variety. On this account, it is unsurprising that varieties of the same species result in different palatability and nutritional quality due to domestication and selection (Bayhan & Bayhyan, 2017; Chomicki et al, 2019). For example, in laboratory experiments with watermelon, the crimson tide cultivar was preferred by C. elaterii and guaranteed the shortest development time (Bayhan & Bayhyan, 2017).…”

“…Larvae and adults feed on the same Cucurbitaceae plants, attacking leaves but sometimes flowers and fruits Ali & Saeady, 1980;Liotta, 1964). This pest is also a vector of plant viruses and diseases (Bayhan & Bayhyan, 2017). Some observations about food preferences among cucurbits and development on different host species have been reported for melon ladybird Ali & Saeady, 1980;Awadalla et al, 2011;Bayhan & Bayhyan, 2017;El-Abdin & Siragelnour, 1991;Wool & van Emden, 1981).…”

Still, none of these research works investigated both aspects and they mainly focused on snake cucumber (Cucumis melo var.…”

Diurnal and seasonal rhythm of the melon ladybird - Epilachna chreysomelina (Coleoptera, Coccinellidae) activity in the conditions of the Kashkadarya region of Uzbekistan

“…And during the rest period, it is quite typical to be in a state of suppression or absence of locomotor activity, nutrition, in some cases, inhibition of gas exchange, digestion, and development. The issue of diurnal and seasonal rhythms of behavior and physiological processes in different species of insects has been studied by a number of authors [1][2][3][4][5][6][7][8].…”
