This invention relates to plant breeding and the protection of plants from insects. More specifically, this invention includes novel transformation events of cotton plants comprising one or more polynucleotide sequences, as described herein, inserted into specific site(s) within the genome of a cotton cell. In highly preferred embodiments, said polynucleotide sequences encode “stacked” Cry1F and Cry1Ac lepidopteran insect inhibitory proteins. However, the subject invention includes plants having single cry1F or cry1Ac events, as described herein. Additionally, the invention is related to cotton plants derived from that transformation event and to assays for detecting the presence of the event in a sample. More specifically, the present invention provides DNA and related assays for detecting the presence of certain insect-resistance events in cotton. The assays are based on the DNA sequences of recombinant constructs inserted into the cotton genome and of the genomic sequences flanking the insertion sites. These sequences are unique. Based on these insert and border sequences, event-specific primers were generated. PCR analysis demonstrated that these cotton lines can be identified in different cotton genotypes by analysis of the PCR amplicons generated with these event-specific primer sets. Thus, these and other related procedures can be used to uniquely identify these cotton lines. Kits and conditions useful in conducting the assays are also provided. These materials and methods can also be used to assist breeding programs to further develop traits in cotton.

Disclosed is a novel Lepidopteran- and Coleopteran-active delta-endotoxin polypeptide, and compositions comprising the polypeptide, peptide fragments thereof, and antibodies specific therefor. Also disclosed are vectors, transformed host cells, and transgenic plants that comprise nucleic acid segments encoding the polypeptide. Also disclosed are methods of identifying related polypeptides and polynucleotides, methods of making and using transgenic cells comprising the novel sequences of the invention, as well as methods for controlling an insect population, such as the Western Corn Rootworm and Colorado potato beetle, and for conferring to a plant population resistance to the target insect species.

Tandem pore domain weak inward rectifying K+ (TWIK) channel nucleic acids and proteins that have been isolated from Drosophila melanogaster and Leptinotarsa are described. The TWIK channel nucleic acids and proteins can be used to genetically modify metazoan invertebrate organisms, such as insects, coelomates, and pseudocoelomates, or cultured cells, resulting in TWIK channel expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to identify candidate compounds which are potential pesticidal agents or therapeutics that interact with TWIK channel proteins. They can also be used in methods for studying TWIK channel activity and identifying other genes that modulate the function of, or interact with, the TWIK channel gene.

This invention relates to the use of a combination of different proteins insecticidal to Helicoverpa zea or Helicoverpa armigerain an insect resistance management process, wherein such proteins are: a) a Cry2A protein such as Cry2Aa, Cry2Ab, or Cry2Ae and b) a Cry1A, Cry1F or VIP3A protein, particularly wherein such proteins binds saturably to the insect midgut membrane of Helicoverpa zea or Helicoverpa armigera, as well as plants and seeds expressing such combination of proteins, which are used to delay or prevent the development of resistance in populations of such insect species.

Disclosed are novel synthetically-modified B. thuringiensis chimeric crystal proteins having improved insecticidal activity and broader insect host range against coleopteran, dipteran and lepidopteran insects. Also disclosed are the nucleic acid segments encoding these novel peptides. Methods of making and using these genes and proteins are disclosed as well as methods for the recombinant expression, and transformation of suitable host cells. Transformed host cells and transgenic plants expressing the modified endotoxin are also aspects of the invention.

Also disclosed are methods of making and using these transgenic plants, methods of making recombinant host cells expressing these delta -endotoxins, and methods of killing insects such as Colorado potato beetle (Leptinotarsa decemlineata), southern corn rootworm (Diabrotica undecimpunctata howardi Barber) and western corn rootworm (Diabrotica virgifera virgifera LeConte.

The present invention is directed to controlling pest infestation by inhibiting one or more biological functions in an invertebrate pest. The invention discloses methods and compositions for use in controlling pest infestation by feeding one or more different recombinant double stranded RNA molecules to the pest in order to achieve a reduction in pest infestation through suppression of gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and to particular combinations of transgenic pesticidal agents for use in protecting plants from pest infestation.

Provided are compositions and methods of use for insect cells comprising baculovirus encoding non-surface expressed proteins and peptides. The claimed invention particularly relates to compositions comprising insect cells containing baculovirus that express cytokines. Such compositions may be administered by, for example, direct intratumoral injection into tumors in mammals, resulting in tumor reduction or recission. Another aspect of the claimed invention concerns methods of promoting resistance to the reoccurence of tumors in mammals who have undergone such tumor recission. In a specific aspect of the claimed invention, the mammals are human subjects presenting with various forms of cancer.

Also disclosed are novel B. thuringiensis genes and their encoded crystal proteins, as well as methods of making and using transgenic cells comprising the novel nucleic acid sequences of the invention.

A micro air vehicle (MAV) comprises features that emulate insect-like topology and flight, including a dangling three part body (100a, 100b, 100c), wing-like dual side rotors (107, 107a) positioned to either side on rotor arms (103) providing tilt and teeter motions to vector thrust and allow crawling along improved surfaces, and elevators (101) that approximate the center of gravity and center of pressure control employed by insects via the inertial reaction and aerodynamic influence of a repositionable abdomen. Control, sensing, surveillance, and payload elements (114), (401), (402), (403), (404), (405), and (407) enable transmission of surveillance and engagement of an emerging target. Left and right perch hangers and grapples (112, 112a) allow perching on various structures, and energy storage (504) and (505) combined with power line (500) and solar (502) energy scavenging circuitry allow extended loiter and mission duration by replenishing onboard energy supplies.
