A study was made of neonate larvae of Phthorimaea operculella.Host finding from soil-laid eggs and dispersal from hosts and nonhosts were first examined. Of first-instar larvae hatching from soil-laid eggs, 80% found the potato plant while roughly 50% found each of the other three plants (datura, tobacco, and tomato). Dispersal from potato, datura, and tobacco was very low, while on tomato it was higher and a high mortality was observed in the 24 h period. Dispersal from nonhost plants was high… Expand

Host utilization is mediated by movement of pre‐feeding Phthorimaea operculella larvae in the Nicotiana tabacum agroecosystem
TLDR
Phthorimaea operculella larvae appear to utilize suboptimal N. tabacum host tissue to maximize their chances of survival, and are able to move within and between plants. Expand
Effects of leaf surfaces on first-instar Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) behaviour
TLDR
The behaviour of neonate H. armigera larvae on leaves from a variety of food plants and on two artificial diets was detailed, indicating that larval food choice or host choice by the ovipositing adult moth may have important implications in larval survival. Expand
Oviposition of the Saltmarsh Caterpillar Moth (Lepidoptera: Arctiidae) is Influenced by the Presence of Host Plant and Time of Day
TLDR
No difference in the number of mature eggs in females exposed to plant material compared to those not exposed, however, the same females laid more eggs in the presence of host plants compared to females deprived of plant material. Expand
Influence of Chemical Cues from Host Plants on the Behavior of Neonate Estigmene acrea Larvae (Lepidoptera: Arctiidae)
TLDR
Feed preference tests revealed that larvae prefer feeding on soybean over maize and tomato foliages, and the locomotory behavior of larvae was clearly affected by hexanic and methanolic soybean extracts. Expand
Foraging Behavior of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) First Instar Larvae on Selected Cotton Varieties
TLDR
Information on the foraging behavior of larvae on cotton varieties will assist researchers to interpret field data and thereby help with the development of pest management decisions. Expand
On-Plant Larval Movement and Feeding Behavior of Fall Armyworm (Lepidoptera: Noctuidae) on Reproductive Corn Stages
TLDR
Corn leaves of reproductive plants were not suitable for early instar development, but silk and kernel tissues had a positive effect on survival and development of fall armyworm larvae on reproductive stage corn. Expand
The Potato Tuber Moth, Phthorimaea operculella (Zeller), in India: Biology, Ecology, and Control
TLDR
Field releases of Copidosoma koehleri and Chelonus blackburni integrated with Bacillus thuringiensis and Phthorimaea operculella granulosis virus are effective in areas having moderate temperature and high RH and dry leaves of Eucalyptus, Lantana, Ageratum, Eupatorium, soapnut, and wheat straw offer significant reduction in infestation. Expand
Decoding Phthorimaea operculella (Lepidoptera: Gelechiidae) in the new age of change
TLDR
This review provides key highlights of current information available that could be used as a resource to fight this pest and traditional control methods are effective in controlling P. operculella. Expand
Larval Food Plants Affect Flight and Reproduction in an Oligophagous Insect Herbivore
TLDR
It is suggested that the effect of host quality on adult dispersal is mediated primarily by biomechanical factors, such as wing loading, and variations in larval food plants and in the tendency of adults to fly correspond with femaleWing loading, energy reserves, and reproductive output. Expand
Oviposition deterrence of shoots and essential oils of Minthostachys spp. (Lamiaceae) against the potato tuber moth
TLDR
There was genetic variation for oviposition deterrence in the potato tuber moth and resistance to repellent plants might evolve thereafter. Expand

Mass culture of Macrocentrus ancylivorus and its host, the potato tuber moth
TLDR
The surveys showed, however, that the moth was so widespread in the peach-growing areas that the proposed eradication campaign was inadvisable and the program resolved itself into retarding the spread of the moth into uninfested districts, the development of methods of control for use when control became necessary, and the introduction and release of insect enemies.

Climbing by newly hatched larvae of the spotted stalk borer Chilo partellus to the top of sorghum plants
