The feeding preferences of individuals within a single species of marine consumer can differ because of variation in ontogeny, physiological state and environmental conditions; yet genetic variation can also play a central (largely undescribed) role. This study describes the nature of the genetic inheritance of feeding preference in the herbivorous amphipod Ampithoe longimana. Two populations k...

Since the halophytes species have an important role in such ecosystem balance and they have been grazed by livestock as supplementary forage, the awareness of livestock's desire to grazing and their preference values of these species is of high priority. Regardless of the importance of halophyte species in the livestock feeding in Iran, there is less published research on the livestock grazing ...

The biological and behavioural parameters of Anisopteromalus calandrae (Hym.: Pteromalidae), a parasitoid of Callosobruchus maculatus (Col.: Bruchidae) on Chickpea were studied in laboratory conditions at temperature of 25±1ºC, photoperiod 16:8 (L:D) and 20±5 % RH. The pre-adult period of the wasp was 19.82 ± 0.038 days and pre-ovipositional period in this wasp was so short that female laid egg...

Ann. Entomol. Soc. Am. 89(2): 252-260 (1996) ABSTRACT The biologies of the sympatric, cryptic species, Trupanea nigricornis (Coquillett), a flower head-infesting fruit fly attacking a wide range of hosts in 8 tribes, 33 genera, and at least 71 species of Asteraceae, and T. bisetosa (Coquillett), an oligophage attacking only 6 hosts in 4 genera of the tribe Heliantheae, are described and compare...

Female Edovum puttleri Grissell [Hymenoptera: Eulophidae], reared from eggs of Leptinotarsa decemlineata (Say) or Leptinotarsa texana Schaeffer [Coleoptera: Chrysomelidae], were videotaped as they attacked egg masses of L. decemlineata containing 20 host eggs. We identified 15 components of ovipositional behavior. Parasitoids reared on L. texana attacked and oviposited in significantly more hos...

Study on the livestock diet is one of the main priorities in the management of rangeland in Iran. So, this study was conducted to compare preference values of plant species in three age classes of Kaboudeh sheep (one, three and five year old ones) in rangelands of Bavanat, Fars province, Iran. For each age class, four sheep were selected and their grazing times from different plant species were...

The studies on screening of 15 varieties wheat viz., WH 1105, 1124, 1142, 283, 542, 711, 1080, 1025, 157, DBW 17, DPW 62150, HD 2967, PBW 343, C 306 and 147 for ovipositional preference (choice no choice test), adult emergence grain damage (number weight basis both) by S. oryzae were carried out under laboratory conditions during August to October, 2017. Results revealed that the minimum ovipos...

The western corn rootworm (WCR,Diabrotica virgifera virgifera LeConte) is an important pest of corn. Annual crop rotation between corn and soybean disrupts the corn-dependent WCR life cycle and is widely adopted to manage this pest. This strategy selected for rotation-resistant (RR) WCR with reduced ovipositional fidelity to corn. Previous studies revealed that RR-WCR adults exhibit greater tol...
